Subtitle (iOS)
Definition
The 30-character line beneath your app name on the App Store, indexed for keywords and used to communicate value.
What it means
The iOS subtitle is a short line (up to 30 characters) shown under the app name. It is indexed for search, making it the second-most-valuable place to put keywords after the title, and it also helps convey your app’s value at a glance.
Because space is tight, the subtitle should add new keywords not already in the title and frame a clear benefit. Google Play’s rough equivalent for conversion is the short description.
Frequently asked questions
Is the iOS subtitle used for keyword ranking?
Yes. The App Store indexes the subtitle, so it’s prime keyword real estate — use it for important terms you couldn’t fit in the title rather than repeating ones you already used.
