Store character limits
Each store cuts text that runs past its limit, and App Store Connect and the Play Console won't save it. These are the limits this counter checks:
- App Store app name: 30 characters. Shown under the icon and in search. Indexed for search.
- App Store subtitle: 30 characters. Shown under the name. Indexed for search.
- App Store keywords: 100 bytes. Hidden, comma-separated, counted in bytes. Indexed for search.
- App Store promotional text: 170 characters. Above the description. Can change without a new build. Not indexed.
- App Store description: 4000 characters. Not indexed for App Store search, but it sells the app.
- App Store what's new: 4000 characters. Release notes for each version.
- Google Play app name: 30 characters. The strongest search signal on Google Play.
- Google Play short description: 80 characters. Shown at the top of the listing. Indexed for search.
- Google Play full description: 4000 characters. Indexed for search: use your keywords naturally.
- Google Play release notes: 500 characters. What's new in this release.
How to use the space well
Put your most important words in the fields that count for search: the name and subtitle on the App Store, and the name and short description on Google Play. Don't repeat a word across indexed fields on iOS, since Apple combines them. Write the description for people: say what the app does in the first lines, because most visitors never tap "more".
