Undo: Quit Habits & Addiction

Quit anything. Privately.

UNDO helps you leave a habit behind, one day at a time: porn, vaping or smoking, drinking, weed, gambling, gaming, sugar, doom scrolling, or something that's yours to name. No account, no feed, no judgement. Your log stays on your phone.

ONE STAMP A DAY
Once a day, UNDO asks one question. Answer "Not today" and the day gets its stamp. Watch your month fill up, pick the calendar style you like (Chain, Marker or Stickers), and see your streak, your best run and, where it fits, the money you've kept.

RIDE OUT EVERY URGE
Urges rise, peak and pass. Tap "I have an urge" and UNDO opens a calm space straight away: breathe along with the circle, or try something to do instead, for the few minutes it takes. When it passes, one tap records that you beat it.

A STICKER BOOK WORTH FILLING
Collect 50 die-cut stickers, holo, glossy and matte, for your days, the urges you ride out, the money you keep and small quests along the way. The ones you're close to start to scratch off, so you always know what's next.

A SLIP ISN'T THE END
Log it honestly and start again. The days you've already banked stay yours, and you'll see what set it off, so the next urge is easier.

KNOW YOUR PATTERNS
See when urges tend to hit and what sets them off, with your full urge history, free.

YOUR PLAN, YOUR REASONS
Save why you're doing this, make if-this-then-that plans for the hard moments, and give the money you keep a goal.
