Five seconds a day. A year of your habits as a quilt of squares, streaks that count honestly, and a hole where you missed.
Chain is a habit tracker that takes five seconds a day and makes the pattern impossible to ignore.
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, an optional daily reminder
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
No account, no ads, no tracking. Everything stays on your phone.
