Most habit apps punish you when you miss a day. Tucan doesn't. It's a binary tracker: done or not. The hero is a monochrome dot grid of your history. One tap, works offline. Miss a day and the hole just sits there. Nothing resets. I built it because streaks made me hide from the app after a Tuesday. That's the opposite of a habit. 7-day free trial, then $1.99/mo or $8.99/year. No feature gates. iOS.
