Block distracting apps. Solve a quick puzzle to unlock them. Memo is the app blocker that makes you earn your screen time. When you reach for a blocked app, Memo stops you and hands you a quick puzzle instead: a Mordle, a Mini Sudoku, a Crowns board or a brain game. Solve it, spin for 5, 10 or 15 minutes, and scroll on your terms. Or realize you didn't want to scroll at all. No willpower needed. Just one small pause that breaks the doomscroll habit. HOW IT WORKS 1. Pick the apps that drain your time: social media, short videos, games, or whole app categories. 2. Block them all day or only during your danger hours. 3. Try to open one and Memo's block screen steps in. Tap Play to unlock and Memo sends you a puzzle. 4. Solve it, then spin for 5, 10 or 15 minutes. When time runs out, the app locks again. WHY IT WORKS - Breaks autopilot: a mindless tap becomes a real choice - Turns scroll time into brain time: every unlock trains memory, focus, and logic - Feels like a game, not a punishment: streaks, personal bests and leaderboards keep you coming back 3 PUZZLES + 6 BRAIN GAMES Mordle, Mini Sudoku and Crowns, plus Visual Memory, Number Memory, Chimp Test, Math Sprint, Color Match and Reaction Time. You choose which ones can unlock your apps. MEET MEMO Your Memo's mood follows your time on blocked apps. Less scrolling keeps him thriving.
