Most people don't fail to quit nicotine pouches because they're weak. They fail because "just stop" isn't a plan. UNDONE gives you one — for both kinds of pouches: the ones you choose, and the ones that happen on autopilot. THE POUCHES YOU CHOOSE Tell us your brand, strength, and daily count — UNDONE builds a day-by-day schedule that steps you down at a pace you pick: 30, 60, or 90 days. Not ready for zero? Get Control mode tapers you to a ceiling you choose instead. Quit later, when you're ready. THE POUCHES YOU DON'T Cravings are the automatic ones. When one hits, UNDONE shows the replacement YOU committed to for that exact trigger (cold brew for the coffee ritual, 4-7-8 breathing for work stress) and starts a 15-minute ride-out timer. Every ride-out is logged with the result. SEE WHAT ACTUALLY WORKS FOR YOU UNDONE records planned and craving pouches separately — so you can see your own patterns instead of guessing. Best Weapons ranks your replacements by YOUR win rate. Trigger Grip shows each trigger loosening week over week, from your own logs. Connect Apple Health and every ride-out counts as a Mindful Session. COACH MURPH, YOUR AI CORNER MAN Proudly AI: doesn't sleep, doesn't judge, texts back at 3am. Murph knows today's schedule, your triggers, your streak, and what worked for you last time — and talks like a corner man between rounds, not a wellness brochure. BUILT TO KEEP YOU HONEST • One-tap logging with honest timestamps — even offline • Skip a pouch you don't need and watch the plan adapt • Streaks, milestones, and money-saved tracking • Weekly recaps that tell you the truth (data doesn't judge) • Optional pouch-time reminders so the schedule runs itself YOUR DATA IS NOT FOR SALE No ads. No selling your data. Anonymous usage analytics only — so we can make the app better. Health data is used solely to run your plan. Subscription with a 7-day free trial, price shown before you start. UNDONE is behavioral support, not a medical device, and doesn't provide medical advice — talk to your doctor about nicotine replacement therapy options. The next pouch is either planned or it isn't. UNDONE handles both. Terms of Use: https://getundone.app/terms Privacy Policy: https://getundone.app/privacy
