Which App Should You Use to Track 75 Hard, 75 Soft, or Exodus 90?
5 min read · Updated 2026-08-04
75 Hard, 75 Soft, and Exodus 90 already have their own apps, built for exactly one program and nothing else. HabitSync makes more sense once you start bending the rules, want a habit to outlive day 75 or 90, or want to know whether any of it moved your mood, sleep, or weight.
75 Hard, 75 Soft, 75 Medium, Exodus 90 - different rules, same basic shape: a handful of specific things you do every day, together, for a set number of days. People stick with that because it works. One committed list beats five separate reminders. The question was never whether to track it - a 75 Hard tracker, a 75 Hard checklist app, whatever you want to call it. It's what you track it with.
What each program actually asks you to do daily
- 75 Hard (Andy Frisella): two 45-minute workouts, one outdoors, a gallon of water, a strict diet, no alcohol, no cheat meals, 10 pages of a non-fiction book, and a progress photo, every day. Miss one requirement and you start over at day 1. No exceptions. A 75 Hard tracker or 75 Hard checklist app exists mostly to enforce that one rule.
- 75 Soft and 75 Medium: community versions built for sticking with it instead of restarting - one workout instead of two, water is just "enough," you set your own diet rule, and the all-or-nothing restart is gone. A 75 Soft challenge tracker usually reflects that: fewer hard stops, more room to adjust.
- Exodus 90: 90 days of daily prayer, scripture reading, exercise, cold showers, and cutting out alcohol and most media, plus a weekly check-in with a small group (a 'fraternity') to keep you honest.
The official apps are built for exactly one program, and nothing else
Andy Frisella has his own 75 Hard app. The Exodus 90 app, run by the ministry behind the program, exists too, and it's built to keep going past day 90 into ongoing formation, not just the 90 days. If you're running either program exactly as written, a 75 Hard challenge app or an Exodus 90 app is a fine default - the checklist, the restart rule, the day count, all built in already.
The trouble starts the moment you change anything. Swap the non-fiction chapter for scripture, which plenty of faith-based 75 Hard groups do, and now you're fighting a fixed checklist or tracking that one habit somewhere else entirely. Finish 75 Hard specifically and usually your data disappears with it.
What a general tracker gets you that a single-purpose one can't
- "Follow a diet" becomes a habit you name yourself, not a slot in someone else's template - a yes/no habit worded however makes sense to you. A gallon of water becomes a numeric habit with your own target. Swap in scripture reading and it's just a different habit, not a workaround.
- The habit doesn't end when the program does. If two workouts a day turned into something worth keeping at a lower intensity, that's the same habit still running, not a new one starting from zero.
- You get to find out if any of it worked. HabitSync's correlation insights can show whether your mood or sleep tracked with the days you hit everything, versus the days you didn't. Neither official app answers that. They track completion. Not what completion did to anything else.
- For Exodus 90's weekly check-in specifically, HabitSync Groups is built for exactly that comparison - everyone in the group sees the real numbers behind each other's check-ins, not just a shared streak count.
At a glance

| Keeps working after the last day | No, ends at day 75 | Yes, continues into year-round formation | Yes |
| Lets you change a rule | No, fixed checklist | No, fixed to the program's disciplines | Yes, every requirement is its own habit |
| Shows if it moved your mood, sleep, or weight | No | No | Yes, via correlation insights |
| Group or fraternity-style check-ins | No | Yes, built in | Yes, via HabitSync Groups |
Setting it up in HabitSync
- Create one habit per requirement, not one big checklist item - the workouts, the water, the reading, and the diet rule each become their own habit.
- Match the habit type to what you're measuring: yes/no for a diet rule or a workout, numeric for a water or page-count target, percentage for something looser like hitting most of a routine most days.
- Name a substitution honestly. If scripture reading replaced the non-fiction chapter, call the habit "Scripture reading," not "Reading" - your history should say what you actually did.
- Log the same habits every day for the length of the program, then keep whichever ones are worth keeping once it's over.
- Check correlation insights partway through to see whether the days you hit everything line up with a real change in your mood, sleep, or weight.
If you're doing one of these, here's the honest read
If you want the program exactly as designed, restart rule and all, the official app is simpler, and that's what it's for. If you're running your own version - 75 Soft, a faith-based variant, anything where you've swapped a rule for your own - a flexible tracker fits what you're doing better than a fixed checklist ever will. That's the whole reason HabitSync has three habit types instead of one fixed list: yours, not a template's.
Common questions
Is there an app for 75 Hard?
Yes. Andy Frisella has an official 75 Hard app, and it's a reasonable choice if you're running the program exactly as written. A general tracker like HabitSync fits better once you modify a rule or want the habit to continue past day 75.
Is there an official Exodus 90 app?
Yes, run by the ministry behind the program, and it's built to continue past day 90 into ongoing formation. HabitSync makes more sense if you want to combine it with habits outside the program, or see it alongside your mood, sleep, and weight data.
Can I use a regular habit tracker for 75 Soft or 75 Medium?
Yes, and it's arguably a better fit than an app built around 75 Hard's exact rules, since 75 Soft and 75 Medium are meant to be adjusted. A flexible tracker lets you define your own version instead of working around someone else's.
Does HabitSync have a 75 Hard checklist built in?
No fixed template - you build the checklist yourself, one habit per requirement. That's slower to set up than opening an app with the rules already loaded, but it's what lets you customize any rule, including ones the official app can't.
