About Melatonin: Sleep & App Blocker
"Just one more video" turns into 2 a.m. At two hours a night, that's six years of your life in bed on your phone by 80. Time to get them back.
Melatonin locks your phone at bedtime, keeps it locked until morning, and shows you what last night did for you.
Your phone locks at bedtime. Every night.
Mornings unlock with sunlight, not willpower.
WHAT IT DOES
- Night Lock: At your set time, every app except Phone and Messages locks until morning. No switch to flip at 2 a.m.
- Strict Mode (Pro): No breaks, and the app can't be deleted while it's locked. The only way out is morning.
- Sunlight Lock (Pro): Pick a time in the day. Your apps lock, and they open only when you step outside and show the sky. Ten minutes of daylight helps you fall asleep faster that night.
- Sleep Score: Total sleep, bedtime consistency, and your morning routine, in one number every morning. Works with Apple Watch, or with your iPhone alone.
- Sleep Debt: How many hours you're short over the last two weeks, and when to go to bed tonight to pay it back.
- Sleep Receipt: What those missed hours cost you, in dollars, at your own hourly rate.
- Lock Impact: Your sleep on nights you kept the lock vs. nights you took a break. Real numbers, not pep talks.
- Night Sky: Every day you open Melatonin counts. The days add up from space dust to the Moon, Mars, Saturn, and on day 180, the Sun. When a new one unlocks, you tap the dust on your first screen to break it open.
- Morning Insight: One notification a day on what your brain did while you slept. Plain English, 30 seconds.
YOU DECIDE WHAT LOCKS
Breaks are yours to set: up to 3 a day, 1 to 20 minutes each, and only from inside Melatonin. Add apps that should never lock. Change bedtime any time before it locks. Turn Strict Mode on only when you're ready for it.
PRIVATE & SAFE
Melatonin uses Apple's Screen Time to lock apps. Apple hands us your choices as encrypted tokens, so we can't see which apps you picked. Your sleep data stays on your iPhone unless you sign in to back it up. The sunlight check reads brightness and sky from your camera on the device; no photos are saved or sent. No ads, no tracking.
MELATONIN PRO
Pro adds Strict Mode and Sunlight Lock. Everything else, including Night Lock and your Sleep Score, is free.
Yearly $49.99 with a 7-day free trial, or $9.99 a month. Payment is charged to your Apple Account at confirmation of purchase, or when the free trial ends. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel in Settings > Apple Account > Subscriptions.
