Track consistency, not perfection
A habit tracker built around consistency rather than perfection. Create a habit from a template or your own, choose how often (every day, specific weekdays or a number of times a week) and whether it's a simple check-in or a count toward a daily target. The Today view gives each habit one big tap target, a streak flame and a two-week strip; Week view is a habits-by-days grid you can fill in after the fact; Stats shows current and best streaks, a habit strength score, 7, 30 and 90-day completion, a month calendar, your best days of the week and the last six months. Rest days never break a streak, every seven check-ins earns a shield to protect one missed day, and check-ins earn XP and levels.
Research on habit formation, most famously Phillippa Lally's 2009 study at University College London, found that new habits took anywhere from 18 to 254 days to become automatic, with a median of 66, and that missing a single day did not meaningfully set people back. This tracker is built on that idea. Rest days never count against you, today only counts once it's done, weekly habits are judged by the week, and streak shields let you absorb an occasional miss without losing momentum.
