Strict 75-day challenge checklist: workouts, water, reading, photos, streaks.
Read full description
75 Day: Challenge Tracker is a strict, simple checklist for the popular 75-day challenge. Pick your rules, tick your tasks, take today's progress photo and keep your streak. One-time purchase, no subscription.
CHOOSE YOUR RULES
• Classic: two 45-minute workouts (one outdoors), follow your diet, drink a gallon of water, read ten pages of non-fiction and take a progress photo. Six tasks a day for 75 days.
• Soft: one 45-minute workout, your diet, 3 L of water, ten pages of any book and a photo.
• Medium: 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: build 3 to 8 tasks from timers, water, pages, photos and simple checks, and run them for 30, 45, 60, 75 or 90 days.
TRACK EVERY TASK IN ONE TAP
• Workout timer: a 45-minute countdown that keeps running when you leave the app and notifies you when time is up. Trained without it? Mark it done by hand.
• Water tracker: log in oz or ml with quick-add chips, with optional water reminders through the day.
• Reading: a pages counter that remembers the book you're reading.
• Diet: one check a day, with an optional note.
STRICT WHEN YOU WANT IT
Strict mode is on for Classic, Soft and Medium. Miss a task and the app offers a restart from Day 1, or you can continue and log the missed day. Turn strict mode off for a gentler routine.
PROGRESS PHOTOS THAT LINE UP
The in-app camera has a body-outline guide, grid lines and a 3-second timer, so every daily photo matches the last. Compare Day 1 with today on a before-and-after slider, and share a collage when you're proud of it.
SEE YOUR STREAK
A day-by-day grid fills in as you go. Current streak, best streak, completion rate and days left are on the Progress tab, and every day keeps its tasks, notes and photo. Add the home-screen widget to see your day number, today's progress and your streak at a glance.
REMINDERS
Two nudges a day: morning to start, evening only if something is left. Days roll over at your local midnight, wherever you are.
PRIVATE BY DESIGN
No account and no sign-up. Your photos stay on your device unless you choose to share them. The checklist works offline.
PRICING
Days 1–7 of every challenge are free, with every task type, photos, the Day 1 vs today slider and the home-screen widget. A single one-time in-app purchase unlocks the rest of your challenge, custom challenges and the before-and-after collage, for good. Not ready to unlock? Your challenge waits at Day 8 and your streak stays safe. No subscription and no ads.
