Arc — Habit Tracker

Arc is an Android-native habit and goal tracker that does more than count streaks — it helps you understand the behaviour behind them. WHY ARC Most trackers tell you THAT you slipped. Arc tells you WHY. On-device behavioural intelligence learns your patterns — mood, sleep, time of day — and surfaces the conditions that make a habit stick or slip. Nothing leaves your phone to do it. BUILD HABITS THAT LAST • Five habit types — simple, quantitative, time-based and more • A clean daily grid: tap to check off and watch your identity votes add up • Smart reminders that arrive at the right moment • Habit stacking and implementation intentions SEE THE WHOLE PICTURE • Slip-risk card — your probability of completing each habit, every morning • Correlation matrix — mood × sleep × habit, the why behind a slip • 365-day heatmap and life-area radar • Weekly digest and a Year-in-Review recap IDENTITY, NOT JUST CHECKBOXES Every completion is a vote for the kind of person you're becoming. Arc counts the votes and reflects your identity back to you. EVERYWHERE YOU ARE • Home-screen and lock-screen widgets • A Quick Settings tile to check off without opening the app • Wear OS app, Tile and Complication PRIVATE BY DEFAULT Your data lives on your device. Predictions are computed locally and never leave your phone. Optional cloud sync is yours to switch on — nothing is uploaded until you do. Export everything as JSON or CSV anytime, and delete your account and data whenever you want.
