The app identifier (configured under RELEASE MANAGEMENT > NEW BUILD > INFO) is a unique identifier string that includes the name of the app and the author of the app.

This string is used to identify your app inside the device it is installed on and is also used in a few other situations, such as when setting up push notifications or generating certificates for your app builds.

Aquro will try to set the correct app identifier for your app when the app is created based on your account information, but you may also manually change it while preparing your app for release.

The app identifier should be written in reverse domain name notation.  A reverse domain name notation means that you write your domain name in reversed order and then add the name of your app onto the end.

Example:

Company domain name: example.com
App name: My app

Your app identifier should be: com.example.myapp
