Sleep Lock
Read full descriptionHide 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, Entertainmentβ¦), 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.

Quit sugar for good - in 90 days. Steady turns cutting sugar into a clear, daily plan: track cravings, build a streak, and watch the urge fade. Sugar is engineered to hook you. Steady is built to get you free - not with willpower alone, but with structure, science, and a coach in your pocket. WHY STEADY WORKS Most "quit sugar" attempts fail because they're all-or-nothing. Steady is a guided 90-day program that auto-tapers your sugar budget down to zero - one realistic day at a time. β 90-DAY PLAN A day-by-day path through 4 phases: Reset, Rewire, Rebuild, Freedom. Each day gives you one small action, not a lecture. β TRACK EVERY TREAT Log treats or grams in seconds. A live budget shows exactly how much room you have left today. β BEAT CRAVINGS IN THE MOMENT Hit Panic when a craving strikes: a guided breath, a reset, and a reminder that cravings pass in minutes - not hours. β STREAKS THAT SURVIVE REAL LIFE Build a sugar-free streak, with monthly freezes so one bad day doesn't undo your momentum. β SEE THE PAYOFF Watch your craving level drop week over week, and see the money you save by skipping the sugar. β EARN IT Unlock achievements as you hit milestones - 7 days, 30 days, 60, 90. Quitting sugar, gamified. HOW IT WORKS 1. Answer a few questions so Steady knows your habits and triggers. 2. Follow your daily plan and log what you eat. 3. Watch cravings fade and your streak grow. WHAT YOU'LL NOTICE Steadier energy instead of the afternoon crash. Fewer cravings. A clearer head. And proof - in your streak - that you're someone who follows through. You've tried quitting sugar on willpower. This time, do it with a plan. Steady is free to download and requires a paid Steady Pro subscription after onboarding. Steady Pro includes the 90-day plan, treat and gram tracking, Panic mode, streaks and streak freezes, craving and savings insights, and all achievements. The subscription automatically renews and can be canceled in App Store settings. βββ Medical Disclaimer Steady is not a medical device and does not provide medical advice, diagnosis, or treatment.

The clearest difference is in-app purchases: Steady at none against Sleep Lock's 3. Steady also leads on update cadence (every 9 days vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
