About

Sleep Lock

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.

About

Narcolepsy

Read full description

Living with narcolepsy means the day can turn heavy without warning. This app helps you stay ahead of it. It learns from your logged episodes when you're most likely to get drowsy during the day, and combines that pattern with live signals from Apple Watch (heart-rate variability, heart rate, sleep, daylight and activity) to estimate your current drowsiness risk β€” and warn you before a high-risk window. What you can do: See your live drowsiness risk β€” with a breakdown of why it's rising or falling Get an early warning before your predicted high-risk times Log sleep attacks, microsleeps, cataplexy and more in seconds Keep a clinical sleep diary β€” bedtime, sleep onset, awakenings, efficiency β€” auto-filled from Apple Watch sleep Track medications, including extended-release, with reminders and an intake planner Plan smart power-naps right before your dips Driving mode: tighter monitoring, earlier warnings and break reminders Export a clear report for your doctor Practical guides for everyday life with narcolepsy Private by design: Your data stays on your device. The model runs entirely on iPhone. Important: This app is a self-tracking and organization tool. It is not a medical device and does not provide a medical diagnosis. Risk estimates are guidance based on self-observation and wearable data β€” not a substitute for professional medical advice. Never rely on the app alone for decisions about driving or treatment; always consult your doctor.
