App stores, led by giants Apple and Google, hold considerable sway over the fate of your app.
If the app violates store rules, it won’t be listed in the app store, making it harder for users to find and install it.
These rules are the backbone of the app store’s commitment to user security, experience, and quality assurance.
This article gives a brief overview of the five biggest app stores, then looks at the rules your app must adhere to if you want to market it in these stores.
Major Mobile App Stores
The top three app stores worldwide are the Google Play Store, Apple App Store, and Amazon Appstore. These three stores enjoy more than 85% of the app market share. Microsoft and Samsung also have their own stores, but Google, Apple, and Amazon are the titans.

Google Play Store
The world’s largest app store is the Google Play Store. It’s the primary hub for Android devices. With its open ecosystem, it offers a more diverse range of apps and allows for greater customization for developers.
This flexibility also necessitates rigorous guidelines to prevent threats and ensure quality control. With its vast reach, especially in emerging markets, the Google Play Store is essential for developers aiming for global recognition.
Apple App Store
The exclusive gateway to iOS devices, the Apple App Store is known for its strict guidelines and thorough review process. Hosting millions of apps, it is second only to Google as one of the largest app platforms in the world.
Catering primarily to iPhones and iPads, the App Store is recognized for its premium user base and higher monetization opportunities. Its emphasis on design, user experience, and stringent privacy standards makes it a favored choice for many developers and users.
Initially launched for the Amazon Fire tablets, the Amazon Appstore has since expanded to cater to a broader range of Android devices. While its size is considerably smaller than the Apple App Store and Google Play Store, it offers unique opportunities, especially for apps integrated with Amazon services or looking to tap into the Amazon ecosystem. Its guidelines emphasize user experience and integration with Amazon’s products and services.
The Microsoft Store was created as an app store for Windows 8 and Windows Server 2012 to distribute Universal Windows Platform apps. With Windows 10, Microsoft merged its other distribution platforms into Microsoft Store, making it a unified distribution point for apps, console games, and digital videos.
Microsoft Store offers a unique ecosystem integrated closely with Microsoft’s suite of services. If you’re targeting enterprise solutions or Microsoft’s loyal user base, you may want to consider this platform.
Samsung Galaxy Store
Designed exclusively for Samsung devices, the Samsung Galaxy Store focuses on apps optimized for Samsung hardware, including smartphones, tablets, and wearables. Developers looking to leverage features unique to Samsung devices, such as the S-Pen or Samsung DeX, would benefit from this platform. The store emphasizes apps that provide enriched experiences tailored explicitly for Samsung users.
Google Play Store Guidelines
If you want to market your app to the broadest audience of Android users, the Google Play Store is the place to be. Here’s a detailed breakdown of its guidelines. The standard review process takes about three days. If the queue is long or the nature of your app requires a close review, the process may take up to seven days or longer.

Submission: Developers upload their apps using the Google Play Console. This includes providing detailed metadata, APK files, and other relevant assets.
Automated Scans: After submission, the app undergoes automated scans by Google’s systems, checking for malware, policy violations, and major functionality issues.
Manual Review: Some apps are also subjected to a manual review, mainly if they’ve triggered any flags during the automated scans or if they belong to sensitive categories.
Feedback or Publication: Post review, developers are informed about the status. Approved apps get published, while rejected ones receive detailed feedback.
Key Areas of Focus
Content Guidelines: Google has a clear set of policies outlining permissible content. This includes restrictions on explicit content, hate speech, violence, and anything that promotes harmful behaviors.
App Quality: An app must meet Google’s performance, stability, and responsiveness standards. It should work across a range of devices and Android versions without significant issues.
Design: Google offers Material Design guidelines to help developers create intuitive and engaging user interfaces. While not strictly enforced, apps closely following these guidelines often provide better user experiences.
Technical Aspects: The app must be free from major bugs and crashes and handle user data responsibly.
Monetization and Ads: Google has guidelines on how apps can monetize. In-app purchases must use Google Play’s billing system. Advertisements must be clearly identifiable and not mimic the app’s UI or mislead users.
Privacy and Security Requirements: Apps must have clear privacy policies, inform users about data collection, and seek permissions appropriately. They should also avoid any unsafe practices that might compromise user data.
Common Reasons for App Rejection
Intellectual Property Violation: Using copyrighted material without permission or mimicking other apps can lead to rejections.
Misleading Claims: Apps that promise features they don’t deliver or present themselves falsely are likely to get flagged.
Inappropriate Content: Any app containing or promoting content that violates Google’s content guidelines is subject to rejection.
Unsafe Handling of User Data: Failure to adhere to privacy and security guidelines can lead to rejection, especially with an increased focus on user data protection.
Steps to Address a Rejected or Suspended App
Review the Feedback: Google provides detailed feedback for rejections. Analyze the reasons your app was rejected.
Make Necessary Changes: Address the issues highlighted in the feedback. This might involve fixing bugs, modifying content, or adjusting monetization strategies.
Resubmit: Once you’ve made the changes, you can resubmit the app for review. Ensure you’ve addressed all concerns to avoid subsequent rejections.
Appeal Process: If you believe your app was wrongly rejected, Google offers an appeal process. Here, you can provide further explanations or clarifications to support your case.
You can learn more about publishing your app from Google Play Store’s policy center. You can also find help in the Google Play Developer Community, a Google group where developers can discuss topics related to the Play Store.
Apple App Store Guidelines
Apple’s commitment to delivering a seamless and secure user experience has led to a rigorous app review process. Here’s a deeper dive into what this entails.
Overview of Apple’s Review Process
Submission: Developers submit their apps via Apple’s App Store Connect platform. The app, along with its metadata, is then queued for review.
