Why App Store Metadata Matters
App Store metadata plays a crucial role in your app's visibility and conversion rate. Apple enforces strict character limits that you must adhere to:
- App Name: 30 characters maximum. Your app's primary identifier.
- Subtitle: 30 characters maximum. A brief phrase highlighting your app's value.
- Keywords: 100 characters maximum. Hidden metadata that powers App Store search.
Exceeding these limits will prevent your app from being submitted. Use this free tool to ensure your metadata is optimized within Apple's restrictions.
