Build powerful daily habits. Track streaks, visualize progress with heatmaps and charts — everything saved locally in your browser.
Research by Phillippa Lally found habits actually take 18–254 days to form (66 days on average). Consistency matters more than perfection — missing one day rarely derails progress.
Streaks leverage the "sunk cost" effect positively — the longer your streak, the more you're motivated to protect it. Even a 2-day streak increases next-day likelihood of completion.
Improving by just 1% every day compounds to 37× improvement over a year. Small consistent actions — tracked visually — create powerful behavioral feedback loops.
