The Best 75 Hard Tracker App for iPhone in 2026
Updated October 4, 2026
75 Hard is simple on paper: five daily tasks for 75 days, and you restart if you miss one. Doing it every day is the hard part, and the right tracker makes the difference. Here's how FlexChallenge compares with the official 75 HARD app, Streaks and Habitify.
Why FlexChallenge comes out on top:
- 75 Hard ready to go: the 75 Days: Phase I template sets up the full day in a minute, with Phases II and III to follow.
- Not just 75 Hard: 75 Soft, six more templates, or any custom challenge from 1 to 365 days with your own tasks.
- Proof of progress: daily photos, video clips and voice notes in one gallery.
- Your rules: strict mode for the 75 Hard restart rule, or flexible mode for everything else.
- Private: no account, no ads, nothing uploaded. And at $24.99 a year, it costs less than the official app.

FlexChallenge vs the official 75 HARD app
The official app tracks one program: 75 Hard and its later phases. FlexChallenge tracks that too, with the 75 Days: Phase I template setting up two workouts, a gallon of water, ten pages, a progress photo and your diet as one daily checklist. It also tracks whatever you want to do next.
- Any challenge you can think of. 75 Soft when you need a lighter round, a 30-day reading sprint, a 90-day business push, or a custom challenge with your own tasks and length.
- More ways to log a day. Seven task types, including water, counters, Apple Health steps, photos, video and voice notes.
- Your call on misses. Strict mode enforces the 75 Hard restart; flexible mode logs the miss and keeps going.
- Lower price. $24.99 a year versus $39.99, with a 14-day free trial.
- Private. Your 75 progress photos stay on your iPhone. No account, no ads, no tracking.
FlexChallenge vs Streaks
Streaks is a general habit tracker built around open-ended streaks. There's no 75 Hard template, no countdown to Day 75 and no progress photos, so you'd be setting up the program and counting days yourself. FlexChallenge is built for exactly this: a challenge with a start, a finish line and proof of every day in between. See the full FlexChallenge vs Streaks comparison.
FlexChallenge vs Habitify
Habitify's free plan stops at three habits, fewer than 75 Hard's five tasks, so you'll need Premium. Even then there's no 75 Hard template, no progress photos and no finish line, and syncing needs an account. FlexChallenge gives you the full program on day one, with nothing to sign up for.
What to look for in a 75 Hard tracker
- All five tasks in one checklist, so the day is done when the list is.
- A clear restart rule that matches how you're running the challenge.
- Private progress photos. You'll take 75 of them; know where they're stored.
- A late day-end time if you train after midnight, so the workout counts for the right day.
- Something for Day 76. The best app is one you keep using after the challenge ends. FlexChallenge lets you start the next challenge straight away.
