Take on the 75 day challenge your way. Pick 75 Hard, 75 Soft, or build a Custom challenge with your own rules, then check off your tasks every day for 75 days. CHOOSE HOW STRICT YOUR CHALLENGE IS - 75 Hard: the canonical rules. Two workouts, water, reading, diet, progress photo. Miss a day and you restart from day 0. For purists. - 75 Soft: the gentler version with achievable daily tasks and grace days. - Custom: your tasks, your rules, your 75 days. GRACE DAYS - MISS A DAY WITHOUT LOSING EVERYTHING On Soft and Custom, a missed day does not wipe your progress. Instead, one day is added to the end of your challenge. You stay accountable without losing weeks of work to one bad day. (Hard keeps the classic day 0 restart.) EVERYTHING YOU NEED TO FINISH - Daily checklist for your preset's tasks: workouts, water, reading, diet, progress photo - Built-in water tracking - Progress photo timeline: watch 75 days of change side by side - Streak calendar with milestone celebrations along the way - Home Screen widget with today's tasks, so the challenge stays in front of you - Daily reminder at the time you choose WHY PEOPLE SWITCH TO THIS TRACKER Most 75 hard challenge apps force one rulebook and reset you to day 0 the moment you slip. This one lets you decide how strict to be, tracks your water without a second app, and turns your daily photos into a timeline you will actually want to look back on. Whether it is your first attempt or your fifth restart, day 1 starts today. 75 Hard Challenge Day Tracker is a subscription app. Payment is charged to your Apple Account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel anytime in Settings.
