Watch face cannot be installed as a standalone

Hi

Did you see this tutorial

I think you may be setting the mobile app as a companion app it is not.

In the Wear OS Quality Guide it says

|Companion app|Companion app|WO-P5|For non-standalone apps, ensure that the companion app can connect with the Wear app and allows the user to use the Wear app as expected.

For more information, see Core app quality.|

A watch app is considered either standalone or non-standalone:

  • Standalone: a completely independent app that does not require a phone app for core features, including authentication. If available, a phone app provides only optional features.
  • Non-standalone: a dependent app that requires an app on a phone or another device for core features, including authentication.
