About the startup
Brainfool is the anti-endless puzzle app. Open it, get exactly one puzzle for today, finish or quit, get a silly roast or pep talk, then come back tomorrow. It rotates Sudoku, Binary/Takuzu, Nonogram/Picross, and 7x7 Slitherlink. Offline-first. No streaks, no leaderboards, no social, no ads mid-thought. Same day, same puzzle on your device. Built for a short session, then leaving. Not another daily habit prison — a small daily ritual.
