What is App Review Guideline 2.3.10?
Apple's App Store Review Guidelines explicitly state under Section 2.3.10:
"Make sure your app's metadata and visual assets do not include references to other mobile platforms, such as Android, Google Play, Windows Phone, or competitor hardware."
While this rule sounds simple, it accounts for more than 34% of first-submission metadata rejections in cross-platform development studios using Flutter, React Native, or Unity.
Why Cross-Platform Studios Get Hit Most Often
When studios release an app on both Google Play and the App Store, copywriting is often drafted simultaneously. Common pitfalls include:
- Subtitle & Promo Text Copy-Paste: Phrases like "Also available on Android" or "Syncs with Google Play games" copied from marketing briefs.
- Device Hardware in Screenshots: Showing an Android device frame (e.g. Pixel or Galaxy punch-hole camera) in App Store screenshots.
- What's New Notes: Including patch notes mentioning "Fixed Android crash on Samsung S24".
How Apple Reviewers Detect Violations
Apple runs both automated string scanners during the pre-review ingestion phase and manual review inspections:
- Regex string matching: Automated detection of keywords like
android,google play,apk,samsung,galaxy. - OCR screenshot inspection: Text recognition inside screenshot mockups for competitor branding or UI buttons (e.g., "Sign in with Google Play Games").
Step-by-Step Fix Protocol
1. Deterministic Text Replacement
Never submit an App Store Connect update with terms referring to external stores. Replace references with neutral ecosystem terms.
2. Audit What's New and Version History
Reviewers check the localized release notes in every single storefront locale. Ensure shared release templates do not contain multi-platform changelogs.
3. Verify Screenshot Device Mockups
Ensure all screenshot mockups rendered in Figma or design tools use Apple hardware frames (Dynamic Island / iPhone 15/16 Pro geometry) without Android status bars or navigation pill bars.
