75 Challenge75-Day Challenge Tracker
Change yourself in 75 days.
Pick Hard, Soft, or your own rules. Check off each day, build a photo timeline, and keep the challenge alive when life gets in the way. One slip costs you a day, not everything.
Free to download on iPhone. Requires iOS 17.6 or later.
How it works
Pick your preset
Hard for the original rules, Soft for a version you can hold down alongside a job, or Custom to write your own task list and length.
Check off the day
Tick each task as you finish it and add your progress photo. The day only closes when the list is done.
Watch it fill up
The calendar and the photo timeline stack up behind you. By Day 75 you have proof of every single day.
Everything you need to reach Day 75
Hard, Soft, or your rules
Run the original 75 Hard with all six tasks, the lighter 75 Soft, or build a Custom challenge from 1 to 7 tasks over any number of days.
The grace day
Miss a day on Soft or Custom and the app adds a day instead of wiping your progress. Your challenge survives, so you keep going instead of quitting.
A 75-cell calendar
Every day of the challenge on one screen: done, saved by a grace day, missed, or still ahead of you. Tap any day to see exactly what you did.
Photo timeline
Snap a progress photo each day and scroll the whole run back. Put Day 1 next to today and see the change you cannot feel day to day.
Home-screen widget
Your current day and today's remaining tasks on the home screen, so the challenge is the first thing you see instead of something you forget.
Daily reminders
One nudge at the time you choose, so tasks get checked off before the day runs out rather than at 11:58pm.
One honest note: a grace day saves your challenge, not your streak. Your streak counter still starts over, and the Hard preset keeps the original restart rule.
A slip costs a day, not everything
Most people do not quit a 75-day challenge because it is too hard. They quit because one bad Tuesday sends them back to Day 0. The grace day is there so the run you have already put in still counts.
