Your phone follows you into bed. "One more video" turns into 2 AM, and tomorrow you pay for it. SleepLock is an app blocker built for one job: protecting your sleep. Set your bedtime once, pick the apps that keep you up, and SleepLock locks them every night with Apple's Screen Time. No willpower needed. WHY IT WORKS - Automatic: your apps lock at bedtime and open when you wake up - Personal: see how much sleep late-night scrolling costs you, based on your own answers - Flexible: if you truly need a break, unlock just for tonight. The lock returns tomorrow - Private: your app choices never leave your iPhone WHAT'S INSIDE - Block social media, videos, games, shopping or any app category - Separate schedules for work nights and rest days - Hours won back, protected nights and urges resisted at a glance - Streaks and badges for every protected night - Morning check-in to see how you wake up after locked nights - Optional bedtime and morning reminders HOW IT WORKS 1. Allow Screen Time access 2. Choose the apps that keep you up 3. Set your sleep window 4. Sleep. SleepLock does the rest SUBSCRIPTION SleepLock requires SleepLock Pro. Choose a monthly plan with a 7-day free trial for new subscribers, or a one-time lifetime purchase. Payment is charged to your Apple Account. The monthly plan renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.

Verdict
The clearest difference is device support: ZenFast at 3 against SleepLock's 1. ZenFast also leads on iOS requirement (15.1 vs 17.6). On price, ads and in-app purchases there is nothing between them.
