Build an offline-first Android audio player focused narrowly on sleep and meditation sessions. Users can play local files or downloaded sound packs, select an exact duration, repeat audio seamlessly, schedule gradual chimes, and control voice, background sound, and fade behavior independently. The first version can sell as a one-time purchase, with optional human-recorded sound packs rather than a mandatory subscription.

Multiple current reviews across paid, free, commercial, and public meditation products report failures in the same playback workflow. The growing use of generated voices also creates room for a product that clearly labels and offers human-recorded audio.
