Thinking Check
Math, reading, logic and critical-thinking prompts. 1,000+ questions, difficulty you control.
Brain Unlock protects the apps you choose with Apple Screen Time, then opens access after a short thinking check or puzzle — and quietly locks them again when the time is up.

Pick individual apps or whole categories with Apple's Screen Time picker.
A short thinking check or puzzle — quick, varied, and worth a moment.

Math, reading, logic and critical-thinking prompts. 1,000+ questions, difficulty you control.
Spot the matching set by shape, color, fill and count. Calm visual logic.
Trace one path that fills the grid and hits the numbers in order. Planning, not luck.
Watch the tiles light up, then tap them back. A gentle, growing recall challenge.
Brain Unlock swaps the instant tap-and-scroll for a brief, worthwhile moment of thinking. No streak pressure, no endless game loops — just a calmer way back to the apps you chose to guard.
Brain Unlock is local-first. The things that make it work live on your device — not on our servers.
