If you are a small structure, and don't want or need your app to be published on the App Store or the Google Play Store. It is possible to distribute your app internally.
To distribute your app internally, the process is quite similar to a regular publication on the App Store or Google Play.
What differs is that instead of submitting your app production file to the store, the distribution file (.ipa or .apk file), you distribute it yourself directly to your users.
For native apps, the process is different depending whether you distribute the iOS or the Android version.
1. Distributing the iOS version of your app:
To distribute your iOS app out of the App Store, you first need to open an Apple Developer Enterprise account.
This account costs $299 a year and allows you to distribute your app out of the App Store.
2. Distributing the Android version of your app:
To distribute your Android app out of Google Play, all you need to do is have your users download the APK production file (the file you get at the very end of the submission process on your GoodBarber platform).
3. The Web App alternative
If you don't absolutely need to distribute a native version of your app, remember that you also have the web app alternative.
The Web App is compatible with every smartphone, so it may be a good and simple way of distributing your app when you don't need the functionalities of a native app.
To distribute the Web App, all you need to do is give your users the URL to access it. They will be able to open it in their mobile browser, and can access your app content.
You also have the possibility to customize your URL and use your own domain name.
