Maximizing iOS: Tips for Users & Developers

How does Apple review new app releases before approving them for the AppStore?

When releasing a new app on the App Store, Apple follows a thorough review process to ensure that only high-quality and compliant applications reach the users. The process involves several steps:

  • App Submission: Developers submit their apps through the App Store Connect portal, providing essential information such as metadata, screenshots, descriptions, and binaries.
  • Initial Automated Checks: Apple’s system performs automated checks to verify technical requirements, adherence to guidelines, and compatibility with Apple devices.
  • Human Review: Apps that pass the automated checks undergo a human review by Apple’s app review team. Trained reviewers evaluate functionality, user interface, content, and guideline compliance.
    • App Store Guidelines: Apple maintains strict guidelines covering design, content, privacy, security, and legal compliance. The review team ensures adherence to these guidelines, requesting modifications or rejecting apps that violate them.
    • Testing and Compatibility: The review team tests the app on various devices and iOS versions to ensure stability, performance, and compatibility across Apple’s ecosystem.
    • App Content Review: Apple checks for offensive or inappropriate content, copyright infringement, and misleading information. Violations may lead to rejection or requests for changes.
    • Privacy and Security: User privacy and security are paramount for Apple. The review team assesses how the app handles user data, adheres to privacy guidelines, and implements necessary security measures.
  • App Approval or Rejection: Upon completing the review, Apple either approves the app for release or sends a rejection notice to the developer. Rejection notices typically provide specific reasons, allowing developers to address issues and resubmit the app.

The review process duration can vary, depending on factors like app complexity and submission volume, ranging from a few days to several weeks.

Common issues to avoid when submitting an app for review in the App Store

  • App Completeness: Ensure your app is complete, without crashes, broken links, placeholder content, or incomplete information. A trustworthy testing partner can help you with that.
  • Specific Documentation: Some apps require additional documentation for certain scenarios, such as apps for kids with third-party ads, medical hardware integration, or featuring third-party trademarks or copyrighted content.
  • Privacy Policy: Ensure your privacy policy clearly explains the data collected, its usage, data retention, user consent, and deletion policies. Verify that third parties handling user data offer the same level of protection.
  • Clear Data Access Requests: Clearly describe how your app will use user data when requesting access and include a purpose string in the app’s Info.plist file.
  • Accurate Screenshots: Use accurate screenshots that effectively communicate the app’s value and functionality, adhering to the guidelines.
  • User Interface: Design a clean, refined, user-friendly interface that meets Apple’s requirements.
  • Unique App Experience: Create engaging, functional, and feature-rich apps that take advantage of iOS capabilities rather than web clippings or content aggregators.
  • Avoid Repeated Submissions: Submitting similar apps repeatedly can delay the review process. Instead, combine apps thoughtfully into one for a better experience.
  • Honest App Representation: Ensure your app delivers on its advertised features and functionalities without misleading users.
  • Provide Lasting Value: Create apps with significant functionality and content that appeal to a broader user base, avoiding niche or limited-use apps.
  • Proper Entity Submission: Certain types of apps, especially those dealing with sensitive user information or highly regulated fields, must be submitted by the appropriate legal entity.


When using the screen reader VoiceOver, there is a setting for it to translate text in an image and describe images with nothing set by the developer.

For example, if you have a blind manager who receives expense requests with screenshots of receipts, despite your description helping, he could use VoiceOver to hear the text in the screenshot.

However helpful, these tools should not be solely relied on to describe images on web pages. Instead, their purpose is to assist in adding context as required.
