About Chain: Habit Tracker
Chain is the habit tracker that takes five seconds a day and makes your progress impossible to ignore. Tick a habit off, watch the ring fill, and keep the chain going. Every habit gets a year of squares stitched like a quilt: colour where you did it, a hole where you didn't. NEW IN 1.3 • A challenge every month: one habit, one month, four days in five wins the badge. This month's challenge is open to everyone • Milestone moments at 7, 30, 100 and 365 days, with an image to share • Insights: this month against last, the habits that lift each other, your best time of day and when each chain hits its next milestone • Log Next Habit in Control Center, on the Lock Screen and on the Action button • A Best Chain widget that looks great in StandBy, and a Lock Screen line under the clock • Ask Siri "How's my chain?" TICK IT OFF FROM ANYWHERE • Home Screen widgets you can tap: tick a habit off without opening the app • Lock Screen ring, line and inline count • "Log Read in Chain" with Siri, or the Log a habit shortcut • A reminder with a Done button that stays quiet on days you've already done it HABITS THAT FIT REAL LIFE • Every day, certain weekdays, or a number of times a week • Amounts and targets: 8 glasses, 20 pages, 10,000 steps, filled in tap by tap • Apple Health ticks off steps, exercise, mindful minutes and workouts for you • Quit habits: count the days clean, log a slip, keep your best on record • Morning, afternoon and evening groups, so the day reads top to bottom MISSED A DAY? THE CHAIN CAN SURVIVE IT • Freezes skip a sick day without breaking the chain • Pause a habit for a holiday and pick it straight back up • Streak Repair patches a missed day in gold when the freezes run out SEE YOUR YEAR • Week grid to log or fix any day • The year quilt for every habit, with totals, best chain and completion • Stats on your best and worst weekdays, perfect days and longest chains • Notes on any day, and a shareable image of your chain PLANS • Free: three habits, the month's challenge (it doesn't count toward the three), the Next Up and Best Chain widgets, the Lock Screen ring, a daily check-in reminder, the last 90 days of the quilt, one freeze a month, quit counters, notes, Siri and Control Center • Chain Unlimited, one payment, yours for good: unlimited habits, every widget, a reminder per habit, amounts and Apple Health, three freezes a month and pauses, the whole quilt, iCloud backup and CSV export • Chain Plus, monthly or yearly: everything in Unlimited, plus three Streak Repairs at the start of every month, five freezes a month, every theme and celebration, the whole challenge library any time, and Insights. Yearly starts with a 1-week free trial for new subscribers • Small extras: Streak Repair and Freeze Pack, five colour themes with matching app icons, and the celebration pack • Bought Chain before it went free?
