Drift is an ambient soundscape mixer. Layer nature recordings and deep-space field recordings at independent volumes, mix any combination, and let the sleep timer fade things out when you're done. Everything runs offline.
Sounds include rain, flowing water, fire, wind, thunder, plasma waves, Martian wind, and something vast singing nearby.
Features:
* Mix any number of sound layers at independent volumes
* Built-in presets, plus save, recall, and delete your own mixes
* Sleep timer with 15, 30, 60, and 90 minute options
* Background playback with lock-screen and notification media controls
* Voicing for phone speaker, external speakers, or headphones
* Live theme switching, with a colourblind-safe interface (state is never shown by colour alone)
* Fully offline — no network access required after install
* No ads, no tracking, no account
