What it is
Atmo is a free white noise and ambience app paired with a long-form YouTube channel. The two fund each other: the channel earns the revenue, the app stays free — no ads inside it, no account, nothing to sign up for. The honest trade is stated out loud on the home screen: the app is free because the channel pays for it.
The appSix scene worlds with looping film, a mixer for every layer, and a sleep timer that fades to silence. Offline, free forever. See the app →
The channelEight-hour ambience uploads — rain, fireplace, ocean, storms, and the sound-machine sounds people actually sleep to.
Every sound is oursSynthesised from scratch rather than sampled, so nothing is licensed and nothing loops audibly.
