HabitKept: 75 Day Challenge

The habit tracker that counts. Log 6 of 8 glasses and see 75% — not a broken streak. Free, with no account and no sign-up. COUNTS, NOT CHECKBOXES Your habits are numbers: glasses, pages, minutes, reps, ounces, grams. Set a target and a step size, then tap +1, +5, +25. A day you half-did is scored as a day you half-did — 50%, still coloured on your grid, still yours. Nothing "breaks." YOUR REAL WEEK Tu/Th/Sa is a schedule, not four failures. Daily, specific weekdays, X times per week, or every N days — rest days stay neutral instead of turning red. A 3×-per-week habit you haven't done yet on Tuesday doesn't drag Tuesday down. 75 DAYS, ZERO AMBIGUITY A complete 75-day challenge mode: six preset rules, a day counter you can't argue with, a required progress photo, and an evening nudge when you're one rule short before midnight. Miss a rule and strict mode asks the honest question — restart, or switch to flexible and keep going. Finish and you get a certificate worth posting. LOG FROM THE HOME SCREEN An interactive widget in two sizes. Tap +1 on the widget and it is logged — the app never opens, the ring updates in place. Small shows one habit; medium shows three with the last seven days. NOTHING LEAVES YOUR PHONE No account. No sign-up. No email address. No analytics, no ads, no tracking, no network calls at all — it works in airplane mode. Export everything to readable JSON whenever you like. It is your data and you can take it. SEE THE WHOLE MONTH A ring for every habit and an intensity grid where darker means closer to done. Tap any past day to correct it. Per-habit history, current run, perfect days, best day, and totals. FREE All of it. Unlimited habits, the full 75-day challenge, the widget, complete history, export. No paywall, no trial countdown, no upgrade prompts. Dark-first by design. iPhone, portrait. — HabitKept is not affiliated with, endorsed by, or connected to the 75 HARD program.
