LockTimer lets you choose how long apps remain available and how long they stay locked afterward. Instead of blocking apps immediately, set a limited amount of time to use them first. When time is up, the selected apps lock automatically. Access returns when the lock duration ends. Use it before bed, during breaks, before work, or whenever you want to step away from your phone after using it briefly. How It Works 1. Choose the apps to lock 2. Set the time until lock 3. Set the lock duration and start the timer You can also create schedules that lock apps automatically on selected days and times. Timers take priority while running, and active schedules resume afterward. Features • Set the time until apps lock • Set the lock duration • Choose apps to lock • Create schedules by weekday and time • View the remaining lock time • Check timers with Live Activity • Manage multiple timers and schedules The free version lets you create up to two timers and start one timer per day. Pro removes timer creation and daily start limits and enables schedules. Terms of Use https://apps.mishimadesign.com/locktimer/legal.html#terms-en
