The Classic rules, as the app lists them on Today. Soft and Medium ease them; Custom lets you write your own.
Today is the whole app: your workouts, your diet, the water, ten pages and a photo, each a row you tick. The ring counts what is left, water adds up with quick-add chips, and the 45-minute workout timer keeps counting when you leave the app.
The in-app camera has a body-outline guide, grid lines and a 3-second timer, so every daily photo matches the last. Drag the Day 1 vs today slider and the change is right there.
A day-by-day grid fills in as you go. Your current streak, best streak, completion rate and days left sit on the Progress tab, and every day keeps its tasks, notes and photo.
Classic is six tasks and restarts on a miss. Soft and Medium keep the structure and ease the rules. Or build 3 to 8 tasks of your own and run them for 30, 45, 60, 75 or 90 days, with strict mode on or off.
On iPhone, widgets put your day number, progress ring and today's ticks on the Home Screen and the Lock Screen, so you know what is left without opening the app.
No coaching, no feeds, no leaderboards. Just the checklist, done properly.

Two 45-minute workouts (one of them outdoors), follow your diet, drink a gallon of water, read ten pages of non-fiction and take a progress photo: six ticks a day for 75 days. Strict mode is on, so a missed task means the app offers a restart from Day 1.
Yes. Soft is one 45-minute workout, your diet, 3 L of water, ten pages of any book and a photo, with one active-recovery day a week. Medium is one 45-minute workout with three outdoor sessions a week, your diet, 3 L of water, ten pages of non-fiction and a photo. Custom lets you build 3 to 8 tasks from timers, water, pages, photos and simple checks, and run them for 30, 45, 60, 75 or 90 days; custom challenges are part of the one-time unlock.
There is no subscription and there are no ads. Days 1 to 7 of every challenge are free, with every task type, reminders, progress photos and the Day 1 vs today slider.

Your challenge waits at Day 8 and your streak stays safe. The price is shown in the app and in your store, in your currency.
With strict mode on, a missed task means the app offers a restart from Day 1 (your photos and history stay), or you can continue and log the missed day. With strict mode off, missed days are marked and the count carries on. Days roll over at your local midnight, wherever you are.
Yes. Photos are taken in the app and stay on your phone unless you choose to share them. There is no account, no sign-up and no cloud sync.
Two reminders a day if you want them: a morning kickoff, and an evening nudge only when something is still left, plus optional water reminders through the day. On iPhone, widgets also show your day, ring and ticks on the Home Screen and Lock Screen.
75 Day is built for iPhone and for Android phones. The app itself is in English.
75 Day: Challenge Tracker is a habit tracker. It does not give medical, fitness or nutrition advice; talk to a doctor before starting a new exercise or diet routine.
