Features
Read full description

Sleep Lock creates a hard bedtime boundary on your iPhone. Pick the apps that tempt you at night β€” social, games, news, anything β€” set your sleep window, and let iOS enforce what willpower can't. When bedtime starts, your selected apps are shielded using Apple's Screen Time framework. Tapping them shows a calm lock screen instead of opening the app. When your sleep window ends, everything unlocks automatically. -- WHAT STAYS AVAILABLE -- Calls, SMS, alarms, emergency features, and any app you didn't select keep working normally throughout the night. Sleep Lock only blocks what you tell it to. -- FEATURES -- β€’ App blocking β€” shield specific apps, entire categories (Social, Games, Entertainment…), or websites during your sleep window β€’ Custom wake-up alarms β€” schedule alarms that ring through silent mode and Focus, just like the Clock app β€’ Sleep insights β€” optional Apple Health integration shows sleep duration, heart rate, and recovery trends from Apple Watch, Xiaomi, Garmin, or any HealthKit source β€’ Streak tracking β€” see how many nights in a row you've held the line β€’ 5-minute warning β€” a quiet notification before your sleep window starts so you can wrap up β€’ Emergency unlock β€” always available if something important comes up, with a streak reset so it means something -- PRIVACY FIRST -- No login. No account. No analytics. No tracking. No marketing push notifications. Your selected apps are stored as opaque tokens on your device β€” never sent to a server, never visible to us. Sleep data stays in Apple Health. The only data that leaves your device is what's required to validate your subscription. -- HOW IT WORKS -- Sleep Lock uses Apple's Screen Time APIs (FamilyControls, ManagedSettings, DeviceActivity) β€” the same framework that powers iOS's built-in Screen Time. Authorization is granted by you, for your own device. This is not a parental control app. -- SLEEP LOCK PRO -- All features require a Sleep Lock Pro subscription. β€’ Weekly - $3.99/week β€’ Monthly - $9.99/month β€’ Yearly - $79.99/year All plans include a 3-day free trial for new subscribers. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID settings. Terms of Use: https://sleeplock.app/terms Requires iOS 26 or later.
