By default, the system engine is disabled. - Changing the playback speed, changing the pitch, using the equalizer, or MIDI file playback will increase battery consumption. - Settings cannot be fully restored from backups, and exporting playlists to other devices is not supported. I recommend that you use the system music app's playlists. This app and its description contain automatically generated text. This app does not contain any songs.

WatsonMIDI's advantage is price ($1.99 vs $4.99) and ratings volume (8 vs 1). On rating, review sentiment, ads and monetization model there is nothing between them.
