In this post, we'll share tips to help you submit apps that deliver original ideas to your users. When working on your app, focus on creating interesting, unique experiences that aren't already available. Apps that actively try to copy other apps won't pass review, and accounts that repeatedly submit copycat apps or attempt to impersonate a service will be closed. The rules that prevent copycat and impersonator apps from being distributed on the App Store are described in App Review Guideline 4.1: 4.1 Copycats (a) Come up with your own ideas. We know you have them, so make yours come to life. Don’t simply copy the latest popular app on the App Store, or make some minor changes to another app’s name or UI and pass it off as your own. In addition to risking an intellectual property infringement claim, it makes the App Store harder to navigate and just isn’t fair to your fellow developers. (b) Submitting apps which impersonate other apps or services is considered a violation of the Developer Code of Conduct and may result in removal from the Apple Developer Program.(c) You cannot use another developer’s icon, brand, or product name in your app’s icon or name, without approval from the developer. These requirements help make the App Store both a safe place for people to discover apps and a platform for all developers to be successful. Best Practices Here are three best practices that will help you submit apps that follow App Review Guideline 4.1: 1. Submit apps with unique content and features. People want apps that provide unique experiences. Find areas that aren't currently being served and build compelling apps for those audiences. Do: Create apps that provide a new experience or a unique spin on an existing concept. Design original, delightful interfaces that elegantly meet your user's needs. Don't: Don’t imitate the features and functionality of other apps. Don’t copy the look and feel of other apps, such as using an identical user interface design. 2. Make sure App Store metadata only contains relevant information and content you either own or have permission to use. The metadata provided in App Store Connect is used to populate your app's product page on the App Store. People rely on this metadata to learn about your app and what it has to offer. Leveraging the popularity of another brand or app, either by including irrelevant references or protected content, is misleading and won't help your app succeed. Do: Use engaging, descriptive language to describe your unique app. Create original content that best represents your app, such as screenshots showing the actual app in use. Don't: Don't use protected material you do not have the necessary permission to use, such as app icons that are similar to icons of a popular app. Don’t include irrelevant references, such as popular app names or trademarked terms, in any metadata fields. 3. Provide information that is authentic and verifiable. People want to know the developers behind their favorite apps are who they say they are. It's important to continually review and provide up-to-date information, including the developer or company name listed on your Apple Developer Program account, the Support URL listed on your app's product page, and other helpful information. This will enable your users to contact you when they need help and it will also hinder people who may try to impersonate you, your app, or your service. Do: Make sure all information, resources, and documentation related to your account and apps are current and accurate. Don't: Don’t provide inaccurate information or resources, such as directing people to outdated support pages. Don’t provide fraudulent documentation. Accounts that submit fraudulent documentation will be removed from the Apple Developer Program. Support Incorporating these best practices into your app's development will help you submit apps that follow App Review Guideline 4.1. If you need additional assistance, consider taking advantage of one of the following support options available from App Review: If your submission has been rejected, reply to the message from App Review in App Store Connect and request clarification. Request an App Review Appointment to discuss the results of our review. Appointments are subject to availability, and take place during local business hours in your region on Tuesdays and Thursdays. If you believe your app follows the App Review Guidelines, consider submitting an appeal to the App Review Board. Resources Learn about foundational design principles from Apple designers and the developer community. Learn how to create engaging App Store product pages. Note that apps that violate intellectual property rights are subject to removal through the App Store Content Dispute process. If you believe an app on the App Store violates your intellectual property rights, you can submit a claim.

My app has already been released and the latest update which aims to fix problems has been stuck in review for over a week. All emails and messages are being completely ignored. Can someone please reply? It seems I am not the only developer experiencing such poor service.

My app has been stuck in "waiting for review" for over a week now. At first, it was reviewed within a day or two, and I made my changes, but now it seems like nobody is looking at it anymore. I have tried emailing and calling apple for support but I am being completely ignored.

Is anyone else experiencing unusually long App Review times? My app has been in review for about a month now with no progress. After waiting for so long, I cancelled and resubmitted it twice, hoping it might help, but the situation remains exactly the same. I've also contacted App Review and submitted a request for an update, but I haven't received any response yet. At this point, I'm wondering if anyone else has gone through something similar recently. How long did it take to get resolved, and is there anything else I can do besides continuing to wait?

Hi, My app "Stories for Two" has been approved and is ready for distribution, but it's blocked in all 27 EU countries because my DSA trader status has been stuck "In Review" since April 26, 2026 — over 6 weeks ago. I've already submitted all the required information. The "DAC7 Directive" line shows as Active, but "Digital Services Act" remains stuck in review with no way to action it from my side. Has anyone experienced this and found a fix? I've seen someone suggest canceling and resubmitting the review request — is that possible and if so, how exactly? Thanks! Boris

I got macOS Golden Gate developer beta, so Xcode stopped working. Then, I got Xcode 27 Beta because I was super excited about it, but then after adding my build, App Store Connect says that I can't add builds made with Xcode beta for review, and since I have macOS Golden Gate, I can't use non-beta Xcode. How do I either archive as non-beta or downgrade in some way (since I can't go back to macOS Tahoe)? I would like to add my app for review soon.

I am writing this as a final attempt to get some clarity regarding my app review. My app, Wecheerup 360 Booth (App ID: 676214516, Bundle ID: com.wecheerup.wecheerup360booth.ios), entered the review process on April 15, 2026. As of today, it has been in "In Review" status for nearly two months. What frustrates me is not the waiting time itself. I understand that reviews can take longer in some situations. What is becoming extremely frustrating is the complete lack of information. There are no messages in the Resolution Center. There are no requests for additional information. There are no indications that something is wrong with the app. There is simply a status that says "In Review" and nothing else. I have contacted Apple multiple times during this period. Every response I receive appears to be the same generic template stating that my app has not been forgotten and that the review is still ongoing. Whenever I ask specific questions, such as whether there is an issue with the app, whether additional information is needed, or whether there is any estimated timeline, those questions go unanswered. At this point, I feel completely stuck. I joined the Apple Developer Program specifically to publish this application. Since submitting version 1.0.3 on April 13, I have continued developing the product and have already implemented new features and newer versions. The app itself has evolved significantly while the original submission remains indefinitely in review. What I am asking for is not expedited review. I am not asking for special treatment. I am simply asking for communication. If there is an issue, please tell me. If additional review is required, please tell me. If there is a reason for the delay, please tell me. After nearly two months, receiving only generic responses and seeing no activity whatsoever in App Store Connect is incredibly discouraging. I genuinely like developing for Apple platforms, but this experience has been one of the most frustrating developer experiences I have had. Not because of the wait itself, but because there is no transparency, no feedback, and no indication that anyone is actually looking at the case. I would sincerely appreciate any clarification regarding the status of this review.

Hello App Review Team, I wanted to follow up because my app, BitzaHugs, is still showing as Waiting for Review, and I was informed that my case was expedited and in active review. I addressed all previously cited rejection issues and resubmitted the app, but I am still waiting for the review to move forward. App Name: BitzaHugs Support Case #: 102903001544 Current Status: Waiting for Review Expedited Review: Requested again / currently active I completely understand that review times can vary, but because my app has already gone through multiple rejection cycles, the issues have been resolved, and my intended launch date has passed, I would greatly appreciate any update or escalation if possible. Please let me know if there is anything else needed from my side to help move the review forward. Thank you again for your time and assistance, Amanda Benavidez

Hi. I am going through my first App publishing. I had an issue that they cannot login but I don’t understand the issue. For my app login is not required. I have a password needed one time to get in and I provided that in the notes. They shared back the password did not work but I validated again and it is the right password. Any thoughts or feedback. Not really sure what to else to do.

Hello everyone, I would appreciate any advice or insight from developers who have experienced a similar situation. Our app, FORTIS HRIS, was submitted to App Review on May 19, 2026 and has been in "In Review" status since May 20, 2026. It has now been over 21 days without any update. App details: First app on our Apple Developer Organization account Internal HR application for FORTIS GARMENTS LTD. Features include attendance, leave management, payroll, employee directory, and geo-punch attendance Users cannot register themselves; only company employees can log in using company-issued credentials Working review credentials were provided in App Review Information No Resolution Center messages No requests for additional information No rejection Status remains "In Review" We have contacted Apple Developer Support multiple times and opened support cases, but have not yet received any update regarding the review. Has anyone experienced a similar delay with an employee-only business application? Is this normal for internal corporate apps, or should we be taking any additional action? Any guidance or shared experiences would be greatly appreciated. Thank you.

Hi everyone, We are facing an unusually long review delay for our iOS app submission. Our app has been in “Waiting for Review” status for almost 2 weeks now, with no update or movement. We had planned our official launch for 21 May 2026, but the launch date has already passed because the app is still not reviewed/approved. We have already contacted Apple Developer Support and requested assistance, but the status has not changed so far. For context: • App name: SuperWomen • Platform: iOS • Current status: Waiting for Review • Waiting time: Almost 2 weeks • Planned launch date affected: 21 May 2026 • Apple ID: 6759612459 • Case ID: 102898811179 Is anyone else still experiencing unusually long “Waiting for Review” times recently? Also, if Apple Staff can check whether our submission is stuck in the review queue or if any action is required from our side, it would be very helpful. Thank you.

Hello Apple Developer Community and App Review Team, I received a Pending Termination Notice on May 29, 2026, for my account (Developer: Bushra Malik) related to Section 3.2(f), regarding app submissions for Dress Up Fashion: Styling Game. I submitted a formal appeal 10 days ago but have not yet received a response or case number confirmation. I want to provide brief context: Our original Clothing Store Simulator received repeated rejections. Rather than continuing to resubmit the same app, we made the decision to build a completely new game from scratch — new code, new assets, new UI, and a fully revised App Store listing. Nothing from the original submission was carried forward. This was a deliberate good faith effort to achieve compliance, not an attempt to evade review. We also believe an older binary may have been reviewed rather than our latest build — a technical issue we have experienced previously on this account. Our account has 4+ years of publishing history and 25+ live games currently on the App Store. Not a single other app is in rejection or under any violation. We have never engaged in subscription scams, fake reviews, bait-and-switch tactics, or any of the fraudulent conduct described in the termination notice. I am respectfully requesting: Confirmation that my appeal is actively under review A status update or case reference number Any additional information Apple needs from our side We are fully cooperative and have all source code, assets, and submission history available immediately upon request. Thank you sincerely for your time. Bushra Malik Apple Developer Account: Bushra Malik

I have the following situation that I would like to have some advise from the community on. I have an iOS app for Hong Kong Mahjong published on the App Store. The app has been in production since February 2026 and I successfully managed to get 20+ updates approved by Apple. However, my latest update (which just introduced a new feature (play offline with nearby friends via WiFi direct)) gets continuously rejected citing 4.3.0 Design: Spam. I asked the reviewers for more specific feedback on this classification but the answer is always ambiguous. I also opened an appeal with Apple for this almost one month ago but have not received any feedback whatsoever. I do not understand why the app is being classified as spam all of a sudden. While there are a few apps for Hong Kong Mahjong in the App Store my app has distinct features: training mode with live coaching advise (for absolute beginners) support for a full 4 round game (16+ hands) two layout variants (in addition to the classic board game / table layout, I am offering a more accessible list view layout as well) The game uses its own backend which I developed from scratch. Bots make their gameplay decisions using either the proprietary heuristics engine or the proprietary machine learning model. Given all this together, I completely fail to understand the spam classification and I find it extremely unhelpful that Apple reviewers provide the most generic feedback thinkable to a classification which is very nuanced and could be explained by various different things (e. g. metadata, app binary, etc.). There is one thing I would like to give as context, as I am not sure if it contributes to the spam classification: Just before trying to get the latest update approved I submitted a new app, which supports offline play online, for App Store approval. This app was rejected because it was deemed to similar with the app for which I am receiving the spam rejections now. Any advise on how I can get this resolved would be highly appreciated. Here is the link to my app: https://apps.apple.com/app/hong-kong-mahjong/id6758140951

To the Apple Review and Developer Support Teams, We are experiencing the same issue described in this thread: https://developer.apple.com/forums/thread/827016 Our application has been rejected under Guideline 2.1 - Performance because the subscription plans do not load during the App Review process. According to the review feedback, there's an error indicating that the In-App Purchases product list is empty. We are unable to reproduce this issue on our side. The subscription screen works correctly in TestFlight on multiple physical devices and with sandbox tester accounts. The paywall loads successfully, localized prices are returned correctly, and test purchases can be completed without errors. We have verified the following: All subscription products are attached to the submitted app version in App Store Connect. The product identifiers used in the application match the identifiers configured in App Store Connect. The relevant agreements, tax information, and banking details are active and up to date. The same build works correctly in TestFlight. The issue appears to occur exclusively in the App Review environment. This makes it difficult for us to diagnose the root cause or validate a fix. Could you please investigate whether there is an issue affecting StoreKit product retrieval during the review process? Any logs, diagnostics, or guidance on how to reproduce the App Review environment behavior would be helpful. Submission details: Date Submitted: Jun 1, 2026 at 2:01 PM Submission ID: 1260550e-ba11-4cbe-925a-7694f89ce715 Thank you for your assistance.

To the Apple Review and Developer Support Teams, I am writing to request guidance and assistance regarding a persistent rejection my React Native application is facing under Guideline 2.1 - Performance (In-App Purchases). My app has been rejected multiple times with the following specific note: "The In-App Purchase products in the app still exhibited one or more bugs which create a poor user experience. Specifically, the subscription screen failed to load any subscription plans. Review the details and resources below to troubleshoot this issue." The screenshot provided by the review team shows a completely black screen where our paywall options are intended to populate, indicating that the product array is returning completely empty during the review process. The Dilemma: We are completely unable to reproduce this behavior on our end. Everything functions flawlessly within our TestFlight builds across multiple physical test devices and various sandbox tester accounts. On TestFlight, the paywall renders instantly, local pricing fetches immediately via SKProductsRequest, and test transactions process without a single error. Our Current Implementation & Verification: Product Status: All subscription products are explicitly marked as "Waiting for Review" in App Store Connect with one In-App product Rejected for not being attached with a bin but I've since submitted the app once again. All the subscriptions and the in-app product have been actively attached to this specific app submission version. Agreements: The Paid Apps Agreement is active, signed, and fully up to date within our Agreements, Tax, and Banking configurations. Identifiers: We have strictly verified that the hardcoded product identifiers in our React Native codebase match the App Store Connect product IDs exactly. Because this error only occurs within the App Review environment and never in TestFlight or local sandboxes, we are at a loss for how to debug or resolve this issue. Could the App Review team or the Developer Support technical team please clarify if there is a known environment mismatch, storefront routing discrepancy, or specific network configuration (such as IPv6 handling in the review sandbox) that would cause production-ready StoreKit products to return an empty array exclusively to the reviewer? Any direct guidance, logs, or steps on how we can successfully surface our plans to your review team would be deeply appreciated.

Hello to the community. I’m hoping someone here can help me. we have been developing our mobile app with a 3rd party contractor. I used to provide feedback through TestFlight screen shot program and it was great. Straight from my iPhone to the dev team. Screen shots with descriptions of the problem. they recently transferred the app to our account and I think since then we can no longer receive the feedback. in fact, last week I spent 2 hours reviewing the app. Sending tons of screen shot feedback with comments. Thinking they were receiving them. But nothing. when we log into our feedback portal I only see feedback from 70 days ago. And nothing from recent. I made sure that feedback is welcome ( see screen shot ) i tested individual feedback test and got nothing. here are my questions. Is there a way to recover that feedback. Where is it going ? How can I get this feature working properly again so I can effectively and efficiently review the app and provide feedback to the developers.

I'm building a custom keyboard extension that offers voice dictation. Because keyboard extensions are constrained (memory cap ~30–48 MB, restricted audio session access), I delegate recording to my container app: User in a host app (e.g., Safari) taps the mic in my keyboard extension. The keyboard calls extensionContext.open(URL("myapp://dictation")) to launch the container app. The container app records audio via AVAudioEngine + SFSpeechRecognizer, writes the final transcript to the App Group, and signals completion via a Darwin notification. 4. The user is expected to be returned to the original host app (Safari) automatically so they can keep typing. The problem (step 4): On iOS 26.4 I can no longer identify which app was the host. Every previously-known path returns nil for the keyboard extension's host: parent.value(forKey: "_hostBundleID") → returns the literal string parent.value(forKey: "_hostApplicationBundleIdentifier") → returns NSNull xpc_connection_copy_bundle_id on the underlying XPC connection (via PKService.defaultService.personalities[…]) → returns NULL NSXPCConnection.processBundleIdentifier on extensionContext._extensionHostProxy._connection → returns nil proc_pidpath(hostPID, …) → EPERM from the keyboard sandbox LSApplicationWorkspace.frontmostApplication → selector unavailable from the extension RBSProcessHandle.handleForIdentifier:error: → returns an RBSServiceErrorDomain error Without the host's bundle ID, the container app has no way to call LSApplicationWorkspace.openApplicationWithBundleID: (the technique that worked on iOS 25 and earlier). UIApplication.suspend() correctly sends the container to background, but iOS treats us as a "fresh launch" — it returns the user to the Home Screen instead of Safari, because the container app was launched by an extension, not directly by Safari. KeyboardKit's maintainer reached the same conclusion (issue #1014) and shipped 10.4 without the feature. My questions: Is there a public, App-Store-safe API in iOS 26+ for a custom keyboard extension to identify its host application, or for the container app (launched via the extension's openURL) to identify which app initially hosted the extension that opened it? UIOpenURLContext.options.sourceApplication reports the extension's own container, not the actual host. 2. Is there a public mechanism for "return to source app" when the container app was launched by an extension's openURL? Equivalent to the ← Source affordance iOS shows for normal inter-app openURL, but triggered programmatically by the launched app. 3. Some popular keyboards (e.g., 微信输入法 / WeChat Keyboard) still appear to round-trip through their container app on iOS 26.4 and return the user to the original host — including the iOS ← WeChat back affordance in the host's status bar afterward. What's the recommended approach to achieve this? If it requires a specific scene-activation flow, NSUserActivity pattern, or extension-context configuration, please point at the relevant docs. 4. If there is no public path today, is FB22247647 (or a related radar) the right place to track this? Should developers in this position migrate to in-extension audio capture (which has its own significant constraints in keyboard extensions)? I'd much rather not rely on private APIs. Concrete guidance — or even an acknowledgment of which direction Apple intends — would help thousands of custom-keyboard developers who currently have a degraded voice-input experience on iOS 26.4+. Tested on iPhone 12 Pro Max running iOS 26.4.2 (build 23E261), Xcode 26.x, Swift 5. Thanks!

Hello, Our iOS app’s TestFlight external testing build has been stuck in “Waiting for Review” for several days. This is for TestFlight External Testing, not an App Store public release submission. We have already provided the Beta App Review Information, including review notes, test instructions, contact information, and a working demo account. Current situation: App name: Linic Platform: iOS Submission type: TestFlight External Testing Status: Waiting for Review Submitted date: June 4 ~ June 5, 2026 Build number: 1.4.2(8)、1.4.3(9) Bundle ID: com.lincept.linny Beta App Review Information: already updated Demo account: provided in App Store Connect We would like to understand whether this is currently expected queue behavior, whether TestFlight external beta reviews are experiencing delays, or whether there is any additional information we should provide to help the review proceed. Has anyone recently experienced a similar delay with TestFlight External Testing builds stuck in “Waiting for Review”? If so, did contacting Apple Developer Support or submitting an expedited review request help? Thank you.

Hi Apple Team, We're looking for guidance from developers who have successfully resolved a rejection under App Review Guideline 3.2.1(viii). Our app is mPokket: Instant Loan App, a consumer lending application that has been live on Google Play for nearly 10 years. The app is published by Maybright Ventures Private Limited, which owns and operates the mPokket lending business and brand. While consumers know the service as "mPokket," the legal entity behind the business and the developer account is Maybright Ventures Private Limited. Our iOS app has now been rejected twice with the following message: "The app provides loan services but the domains listed on the app's Product Pages are not clearly under your control or ownership." Apple also mentions that the Product Page domains and the email domains of the Apple Accounts associated with the developer account should clearly identify the company providing the loan services. Has anyone faced a similar situation where: The consumer brand name is different from the parent/legal entity name? The developer account is under the parent company while the app is marketed under a consumer brand? App Review requested additional clarification regarding ownership of the lending business and website domains? If so, what documentation or changes helped obtain approval? Did you need to: Change the Account Holder/Admin Apple IDs to use the parent company's domain? Add additional ownership documentation? Provide a corporate structure explanation or trademark/brand ownership details? Any guidance or experience would be greatly appreciated. Thank you.

Hello, I'm hoping someone from the App Review team can look into this situation, which has specific context that I believe makes it worth a careful look. Thank you in advance for your time. I'm hoping someone from the App Review team can look into this situation, which I believe has specific context that makes it worth a careful look. My app YADA: You've Already Met (App ID: 6759586097) has been in "Waiting for Review" since Wednesday May 6 at 7:44 PM ET - now over 96 hours. I have an open support case (20000112508151) filed Friday with no response yet. I'm not writing simply to flag the wait - I want to explain why this submission deserves a thoughtful second look on the merits. When YADA was submitted for TestFlight beta review, it was flagged under Guideline 4.3(b) for the same reason as the App Store rejection. I appealed, explained the differentiating mechanic, and an Apple reviewer evaluated the argument and approved the app for external testing. That approval is on record. I'm asking for consistency with that prior decision. YADA's core mechanic is genuinely unlike any dating app currently on the App Store. A user privately adds someone they already know to a list. That person receives no information about who added them. A match is only revealed when both people have independently and privately added each other. If the feeling isn't mutual, nothing is ever disclosed. There is no browsing of strangers, no algorithmic recommendations, no swiping, and no rejection possible because neither party knows they've been added until both have added each other simultaneously. Critically, YADA does not ask users to declare their gender or sexual preferences - because the mechanic doesn't require it. This makes YADA the only interest-discovery platform on the App Store that works entirely without those declarations, which creates a uniquely safe experience for LGBTQ+ users and young people who are not ready to publicly disclose their orientation. No equivalent experience exists on the App Store. The App Store rejection also included 5.1.1 and 2.1 issues, both of which I fully resolved - redesigning the contacts permission flow with a proper in-app explanation screen and directly answering Apple's question about data handling - with a new build submitted alongside my Resolution Center reply. I'm not asking for special treatment. I'm asking for the opportunity to have the full argument evaluated by a reviewer with the time to consider it, consistent with how the TestFlight review was handled. Support case: 20000112508151. App ID: 6759586097. Submission ID: abdf8b5b-5ea0-46a4-8a0b-fb58320fa701. Thank You

I’m working on an iOS app and need help with ASO to find the best keywords for title, subtitle, description, and keyword field. Can anyone suggest free tools that show keyword volume, difficulty, and competitor keywords?
