Is there a way to create “own” app in Gplay or Astore without the need of installation of AppGyver app itself? I mean the app with my own logo and name in Gplay (Astore)?
Yes! Select Launch > Build Settings from the global toolbar at top for options on how to package your app into a standalone binary. See the docs at https://docs.appgyver.com/publishing/required-build-assets for more info.
