⏱ SLEEP TIMER
Set it and forget it. Choose 15, 30, 45, 60 or 90 minutes and SleepyTones automatically fades out and stops — so you don't have to tiptoe back to turn it off.
🔇 WORKS IN SILENT MODE
Audio plays even when your phone is on silent. Because babies don't care about your notification settings.
📵 100% OFFLINE
All sounds are built into the app. No streaming, no buffering, no surprise data charges. Works on a plane, in a car, in a cabin with no signal.
🔒 PLAYS IN BACKGROUND
Lock your screen, switch to another app — the sound keeps playing. Your lock screen shows playback controls so you can pause or stop without unlocking.
🎚 FULL PLAYBACK CONTROLS
Play, pause, stop, and volume control all at your fingertips. Clean, dark interface designed for tired parents using their phone at 2am in a dark room.
SIMPLE BY DESIGN
No accounts. No login. No onboarding. Open the app, tap a sound, done. Because when a baby needs to sleep, every second counts.
Perfect for:

Newborns and infants (0–12 months)
Toddlers with trouble settling
Nap time and bedtime routines
