SleepDrift is an Android app for sleep, relaxation and concentration. It combines nature sounds, white noise and breathing practice to help you build a calm audio environment before sleep, reduce stress after a busy day and maintain focus during work or study.
You can create your own sound mix from multiple sources: rain, thunder, wind, fire, birds, waves, crickets, cafe ambience and white noise. Each sound has independent volume control, so you can tune a gentle background or a dense noise mask that hides distracting sounds.
