Free and no account needed. Eight glasses. Thirty pages. Two workouts. Your habits are numbers, and HabitKept counts them on the schedule you actually keep. 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. "75-Day Challenge" is our own preset template, and the rules are yours to edit.
