Chain: Habit Tracker

Chain is a habit tracker that takes five seconds a day and makes the pattern impossible to ignore. Free to start, unlimited with a one-time unlock. No subscription. Tick the habit, watch the ring fill, and keep the chain. Every habit gets a year of squares stitched like a quilt: lime where you did it, a hole where you did not. TODAY • Big tactile tiles, one tap to log, a completion ring for the day • A fourteen-day strip under each habit and the current streak beside it HABITS THAT FIT REAL LIFE • Every day, certain weekdays, or a number of times a week • Weekly habits count in weeks, not days, so a Tuesday off does not break a three-a-week chain • Twenty icons, start dates, and a daily reminder at the hour you pick WEEK • A grid of the week to log or undo any day, faded where a habit is not due YEAR • Twenty-six weeks of squares per habit, with totals, best chain and the completion rate STATS • Check-ins all time, 30-day completion, longest chain, perfect days, and which weekdays you actually do the work FREE AND UNLIMITED • Free: three habits and the last 30 days of the quilt, with every other feature • Chain Unlimited, one payment: unlimited habits, the whole year in the quilt, and reminders • Bought Chain before it went free?
