Before you install
A first public beta, with room to grow.
Tested with a Galaxy Watch4 Classic and Galaxy S23. Other watches, ARM64 devices, smaller screens and headphone reconnects still need wider real-device coverage.
Automatic offline playlist refresh and cleanup are experimental; cleanup is off by default. YouTube service changes and restricted content can affect playback or sign-in.
Updates, privacy & release evidence
For in-place updates, keep the same package and signing key. If Android reports a signature mismatch, preserve your data before uninstalling: uninstalling deletes local data. Older upstream and .dev packages have separate storage.
Sign-in is optional. Proxy stream fallback is enabled by default and can be disabled in Accounts. Read the app privacy notice for session storage, external services and deletion choices.
Screenshots show version 0.3.0-beta.1 (41) on Galaxy Watch4 Classic and Galaxy S23. The maintainer confirms the release has the same UI; screenshots precede final APK signing.
Tested on Galaxy Watch4 Classic with Galaxy S23 using an earlier candidate of this release. Wider watch, ARM64, smaller-screen and headphone-reconnect coverage remains limited. Automatic offline playlist refresh and cleanup are experimental; cleanup is off by default. Exact published APKs have package and signature verification; their physical runtime is not separately recorded.
