Pick one habit. Do it every day. Skip once, start over. Unbroken is a single-habit discipline tracker. You commit to 7, 14, or 21 days. You show up every day. If you miss one, you start from zero. That's the whole app. We won't check if you actually did it. You will. That's the point. — What makes Unbroken different — No streak freezes. No grace days. No paid rescue mechanics of any kind. The rule is the rule, and you knew it going in. No gamification. No badges, no levels, no confetti. Discipline isn't a game. No social feed. No leaderboards, no friends, no public streaks. Your habit is yours. No ads. No subscriptions. One $4.99 unlock after three free challenges, forever. No accounts. No cloud. No tracking. Everything stays on your phone. — How it works — 1. Pick one habit from the catalog — or write your own. 2. Commit to 7, 14, or 21 days. 21 is the ceiling. 3. Check in every day. Miss a day, and you restart. 4. Finish, and move on. Or pick a new habit. One at a time. — Supported habit types — • Counted reps (push-ups, squats, pages read) — with optional voice counting • Walking challenges — validated against Apple Health steps — What you get — • A single clear screen showing today's target • One daily reminder, if you want it • A share card when you finish a challenge • Nothing else — Privacy — Unbroken runs entirely on your device. No analytics, no ad networks, no account. HealthKit access (if you pick a walking challenge) is read-only and never leaves your phone. Pick one habit. Do it every day. Start over if you skip. That's the whole thing.
