The sleep app that locks your phone before bed.
Bugs, feature ideas, billing questions — just email us.
We usually reply within 2–3 days. Including your app version (Profile → Version) and iPhone model helps.
Do I need an Apple Watch?
No. Melatonin can measure your sleep with your iPhone alone, for free. If you wear an Apple
Watch or another tracker that writes to Apple Health, it uses that data for a more detailed score.
What if I need an app while it’s locked?
Calls and messages are never blocked. You can also take a short break — up to 3 a day,
1–20 minutes each. If you turn on Strict Mode, breaks are off by choice.
Can you see which apps I block?
No. Apple hands us your picks as encrypted tokens, so we can’t tell what you chose.
Does my sleep data go to your server?
Not unless you sign in, and even then only the nights your iPhone measured — never your
Apple Health data. Details are in our Privacy Policy.
How do I cancel or get a refund?
Subscriptions are handled by Apple. To cancel, open Settings → your name → Subscriptions →
Melatonin. For a refund, request one at
reportaproblem.apple.com.
I got a new phone. How do I get Pro back?
Open the paywall in the app and tap Restore, signed in with the same Apple ID.
How do I delete my account?
Profile → Account → Delete Account. Everything on our server is deleted right away.
