Tally is a habit tracker that looks like a ledger and behaves like one: every habit on one page, every day on the record, and the record kept somewhere you own. EVERY HABIT, ONE PAGE Today's habits sit in one list, grouped under your own headings. Tick a habit, count toward a target (8 glasses of water), or type an amount (30 pages). Each row shows its streak and the last two weeks at a glance. THREE WAYS TO LOOK • Day — today's checklist, with a running score. • Spread — the last 5, 7, 14 or 30 days side by side. • Year — a heatmap for every habit, every day since January. MAKE A HABIT IN ONE CARD Name it, pick a colour, choose which days it's due and how it's tracked, set a streak goal and a heading — all on one card. Type "Take vitamin D" and Tally draws a pill; type "Practise guitar" and it draws a note. Change it whenever you like. BUILD HABITS, OR QUIT THEM Track days done, or days clean. A streak goal gives each habit something to aim at. FIX ANY DAY Forgot to tick yesterday? Open any past day from the calendar and put it right. Add a note to the day, or to a single habit.
