Frequently asked questions
How do I use the app store metadata checker?
Check the length of your app name, subtitle, and keyword field before filling out App Store Connect.
Does the subtitle share the app name limit?
They are separate fields, each with up to 30 characters. The keyword field has its own 100-character limit.
Do I need an account and are my inputs uploaded?
No account is required. Calculations run in your browser. Entered numbers and text are not included in tool analytics events; only the tool ID, language, and action are recorded.
