Pick the apps to lock
Instagram, TikTok, YouTube, whatever eats your time. Choose the quiz difficulty, the themes and how long an unlock lasts.
Screen time, with a brain gate
MindLock locks the apps that eat your evenings. Open one and a short quiz meets you instead of the feed. Answer right and it opens for exactly as long as you chose. Then it locks again on its own.
Free to start · iOS 17 or later · No account needed

How it works
No cold turkey. The apps stay on your phone; they just stop being free.

Instagram, TikTok, YouTube, whatever eats your time. Choose the quiz difficulty, the themes and how long an unlock lasts.
The shield appears where the feed used to be. Five quick questions. Wrong answers cost you a cooldown, not your evening.

For exactly as long as you chose: 30 minutes or three hours. A timer lives in the Dynamic Island, and the lock comes back on its own.
Quiz themes
Questions come from the themes you pick. New themes land without an app update.
Features
Really need the app right now? Three quick unlocks a day, ten minutes each. The next quiz gets one extra question, so it stays honest.
The unlock countdown sits in the Dynamic Island and on the Lock Screen. Relock early with one tap.
Brain reps, streaks, accuracy by theme, a knowledge level that grows with every unlock, and the full history of every quiz.
From Easy to Perfect Run, where a single mistake ends the attempt. Pick the friction that matches the habit.
Which apps you lock never leaves your phone. Apple’s Screen Time framework gives MindLock opaque tokens, not names. No account, no ads, no tracking.
Math and logic for free. Geography, history, animals, movies and more with Pro. Random draws from everything.
The math
Drag to your honest number. Most people land between 2 and 6 hours a day.
At a modest $25 an hour, purely to make the number tangible.

FAQ
Yes. MindLock is friction, not a cage. It is built for the reflex tap, the tenth open of the evening, not for a moment you actually decide to spend online. That is also why there is an emergency unlock.
Locking an app on iOS is only possible through Apple’s Screen Time framework. MindLock uses it to show the shield and to open the app after a passed quiz. It never sees your usage of other apps, and the apps you pick are stored on your device only.
When you tap “Start quiz” on a locked app, a notification is the door into the quiz. Without it you would have to open MindLock by hand every time. MindLock never sends marketing notifications.
The app stays locked and a short cooldown starts before you can try again. On Perfect Run difficulty, one mistake ends the attempt.
Locking, unlocking and timers work offline. Quiz questions are downloaded when you start a quiz, so the first question needs a connection.
Almost nowhere. No account, no ads. Our server sees an anonymous installation ID, a push token for timers and anonymous usage counters. Details are in the privacy policy.
