SleepFix is an Android app for nights when your mind won't switch off. Mix rain, ocean, forest and other calm sounds into your own blend, and wake up to a soft alarm. When a worry keeps you awake, put it in a firefly jar until your set worry time, follow a narrated body scan, or breathe with a slow guide. A 21-day plan helps you build calmer evening habits. No account. No sign-up.
