App Subtitle
The app subtitle is a secondary text field on the Apple App Store (30 characters) that appears below the app name. It's indexed for search and provides additional keyword opportunity.
The app subtitle is an Apple-only field that gives you 30 additional characters for keywords and descriptive text. It appears directly below your app name in search results and on your product page.
Use the subtitle to complement your title with different keywords rather than repeating words. It should communicate your app's value proposition while incorporating search terms you couldn't fit in the title.
Craft the perfect subtitle with AppDrift's metadata generator.

Character Limits
Character limits define the maximum text length for each metadata field in the app stores. Exceeding limits causes submission rejection; optimal usage maximizes keyword coverage.
