TealChain

Every day you keep a habit, you add a link to the chain. Miss a day and the chain breaks. That single idea is the whole of TealChain — and it is surprisingly hard to argue with at 10pm when you are one tick away from keeping a nine-day run alive. TealChain is a habit tracker and to-do list in one app, with no account, no sign-up and no internet connection required. It opens straight onto today. TODAY See every habit scheduled for today, with its current streak and how often you have kept it. Swipe right to complete, swipe left to archive, or tap the ring to tick one off. The chain ring at the top fills toward the daily goal you set, and a seven-bar week strip shows how the current week is running. When several habits are still open, one button forges the rest at once. HABITS THAT FIT YOUR WEEK Start from a library of eighteen ready-made habits across six categories — Health, Mind, Focus, Home, Social and Craft — or write your own with any title, icon, colour and weekly schedule. Every day, weekdays only, weekends only, or any combination of days you choose. Habits you set aside are archived rather than deleted, so their history survives and you can restore them later. A SEPARATE DOCKET FOR ONE-OFF TASKS Habits repeat; some things only need doing once. The Docket keeps those apart from your routine, with light / normal / heavy weights, optional due dates, overdue flagging and filters for open, due-soon and cleared work. Swipe to complete or delete, and clear finished tasks in one go when the list gets long. INSIGHTS THAT ACTUALLY EXPLAIN THE WEEK A bar chart of completed versus scheduled links for the current week. A thirty-day trend line. A breakdown of where your effort is going by category. A sixteen-week calendar heat map where darker teal means a bigger day. And a standings list ranking your habits by which chains are holding best. TEN LAURELS WORTH EARNING First Link, Seven Strong, Fortnight Forged, Month of metal, clean sweep, Century Chain and more. Each one is tied to progress you are already making — total links, longest chain, perfect days, tasks cleared — with live progress bars on the ones you have not reached yet. BUILT TO STAY ON YOUR PHONE TealChain has no servers, no accounts and no analytics. It contains no network code at all and runs identically in airplane mode. Your habits, check-ins, tasks, profile and preferences live in the app's private storage on your device and nowhere else. Uninstalling removes all of it. Also included: a reduce-motion setting that stops every animation, compact rows for longer lists, a Monday or Sunday week start, adjustable daily goal, and a confirm-before-removing toggle. Pick three habits. Tick them off tonight. See how long you can keep the chain.
