Quiet Time gives you simple, flexible control over screen time — without wrestling with Apple's built-in Screen Time settings. Lock distracting apps instantly, then unlock for exactly as long as you choose: anywhere from 15 to 120 minutes. HOW IT WORKS - Choose exactly which apps or categories to lock — Games, Social, Entertainment, or any apps you pick - Tap Lock to restrict your selected apps instantly - Tap Unlock and choose any duration from 15 to 120 minutes - Apps are automatically restricted again the moment time is up - Protected by a PIN only you know, with Face ID as backup if you forget it - See today's total unlocked time at a glance, right on the home screen CYCLE MODE Automatically alternate between screen time and focus locks — no willpower needed. Set your own open and lock intervals, or start from a preset (15/15, 20/15, 25/15, 30/15), then choose how many rounds to run: anywhere from 1 to 10, with 3 as the default. You'll get a quick notification every time a phase ends, so you always know where you stand. Once you've completed your rounds, Quiet Time locks up and stays locked until you're ready to unlock it yourself. WHAT STAYS AVAILABLE System apps like Phone, Messages, Clock, and Maps are never affected, no matter which apps you choose to lock. DESIGNED FOR SIMPLICITY No subscriptions. No accounts. No complicated schedules. Just lock, unlock, and go. Perfect for parents managing kids' screen time, or anyone who wants to step away from distractions. NOTE: Quiet Time requires Screen Time to be turned off in Settings to function properly.

HeiLock helps you set gentler boundaries around app time. When it is time to stop, pause for a moment, cut down on short, mindless bursts of app use, and use apps with more intention. Key features: • Session Limits Set how long an app can be used each time. When the limit is reached, usage is restricted automatically. • Cumulative Limits Set a cumulative usage limit for one or more apps. When the set time is reached, usage is restricted automatically. When you select multiple apps, use “Combined Usage Time” to choose how time is counted: when enabled, usage time across the selected apps is combined, and the apps share a single cumulative limit; when disabled, usage is accumulated separately for each app. • Allowed Time Windows Choose when an app is available. Outside those windows, usage is restricted. • Custom Display Content Add your favorite photos or videos. When an app is locked, HeiLock can show the content you selected, making each pause feel a little warmer. • Manage Multiple Apps Manage multiple apps at once and set different usage schedules for different apps. • Passcode Protection Protect your settings with a passcode to prevent unwanted changes. • Local Storage No sign-in, no ads, and all data stays on your device.
