This article will provide an overview of all the text and design assets that are required to create a branded mobile app.
1. App Name in the app store (Google Play and App Store)
An app name can be up to 30 characters long including spaces. This is what people will see in Play/App Store
2. Icon Display Name (iOS and Android)
This is the name that will be displayed underneath the app icon on a device's home screen once the app is downloaded. While the technical limit is 20 characters, we recommend using no more than 12 characters to avoid getting your app name truncated.
3. Long App Description (iOS & Android)
4000-character limit. This will appear when users find your App in the App and Google Play stores. You can briefly describe your event(s) and highlight some of the main features that you think your participants will find useful.
4. Short App Description (Android)
The first text users see when looking at your app's detail page on the Play Store app. 80-character limit
