Open Tysha and tap a sound to start it — the home screen is the player. Layer more sounds to build your blend; your mix is remembered for next time.

Each active sound has its own level. Bring one up to make it louder, ease it down to soften it, and blend rain, brown noise and a fan into the mix that settles your baby.

Choose a duration and Tysha fades gently to silence when it ends — never an abrupt cut. There's a live countdown on the Lock Screen and Dynamic Island.

Yes. The full sound library, mixer and sleep timer are free forever, no account needed. Lifetime Pro is an optional one-time purchase — never a subscription.

Open Settings in the app and tap Restore Purchases. As long as you're signed in with the same Apple ID you bought with, Pro reactivates. Still stuck? Email us.

No. Pro is tied to your Apple ID. Install Tysha on the other device, open Settings, and tap Restore Purchases.

Purchases and refunds are handled by Apple through the App Store. We can't issue App Store refunds directly, but we're happy to help — just reach out.

Check that your device isn't on silent with media muted, raise the volume, and make sure another app isn't holding audio. Restarting Tysha usually clears it.

Tysha pauses for phone calls and resumes afterward. If it doesn't resume on its own, just tap play again.

Pediatric guidance suggests keeping continuous sound at a gentle level and the speaker a good distance from the crib. Tysha is a comfort tool, not a medical device — use your judgment and follow your pediatrician's advice. See our Terms for the full note.
