75 Hard vs Unbroken: Rules, Flexibility, and Witnesses
Quick answer: They are different kinds of thing. 75 Hard is a program: a fixed set of published rules and a philosophy about not compromising them. Unbroken is an app built on pacts and witnesses — you can run 75 Hard's rules inside it unchanged, or write your own. The differences worth knowing are who writes the rules, whether anyone else can see your days, and what survives a reset.
People search for "75 Hard app" and end up comparing a rulebook with a piece of software. That comparison does not work straight, so here is the honest version of both.
What 75 Hard is
A program with an author and a published standard. Its rules require two workouts a day, "a minimum of 45 minutes long, they must be 3 hours apart from each other, and one of the two workouts MUST BE OUTSIDE", a structured diet with no alcohol and no cheat meals, a gallon of water, at least 10 pages of non-fiction, and a daily progress photo. Miss any task and "you start over at Day 1."
It does not depend on any particular tool. People run it on paper calendars, in notes apps, on spreadsheets, and in trackers. The rules are the product.
What Unbroken is
A 75-day challenge tracker built on two ideas: a pact and witnesses.
You write the pact — the tasks, the rules, the terms of failure — before day 1. Your witnesses see your days as you bank them: one partner in a Linked Fate pairing, or a squad. Miss a day and the run resets to day 1, exactly as a hard challenge should. But the days you already banked stay in the Record, permanently, because 40 days of training happened whether or not the run survived them.
You can run 75 Hard's published rules inside it without changing a word. You can also write something else.
What 75 Hard does well
Give the program its due, because these are real advantages.
One rulebook, no ambiguity. There is a published standard and an author who defends it. When you say you are on day 40 of 75 Hard, everyone knows precisely what you have done.
The severity is the design. The program's own material argues that modifying it defeats its purpose. That is a coherent position. A rule you cannot renegotiate at 9pm in the rain removes the argument you would otherwise lose.
It costs nothing to start. The rules are published. You can begin tomorrow with a notebook.
The outdoor rule is smarter than it looks. Forcing one session outside, whatever the weather, is the part most people want to modify and the part that does the most work.
Scale. Large numbers of people run the same thing, so there is no shortage of company or of examples.
What a rulebook cannot do
A published standard cannot watch you. It cannot notice that you have gone quiet on day 12. It cannot decide anything on your behalf at midnight.
That gap is where tracking matters, and there is evidence for it rather than just opinion. A meta-analysis of 138 experiments with nearly 20,000 participants found that monitoring progress toward a goal improved goal attainment — and that "progress monitoring had larger effects on goal attainment when the outcomes were reported or made public, and when the information was physically recorded."
Recorded. Seen. Those two conditions are what most private tracking leaves out.
Where Unbroken differs
Witnesses, not an audience. A partner or squad sees your days as you complete them. Not a feed of strangers applauding, and not a social network — people who agreed to watch and will notice a gap. That is the part of the research most trackers ignore. The mechanics are covered in why an accountability partner doubles your odds.
The Record. A broken run goes back to day 1. The days you banked do not disappear from your history. This is not a softening of the rule — the run still resets, and the reset still costs you — it just refuses to pretend the work never happened. Deleting your history is not discipline. It is bad bookkeeping.
Custom pacts. Your tasks, your terms, written by you. Some evidence supports this: a 2024 review found habits that were self-selected were more successful than those assigned without the person's choice. Note the honest caveat that goes with it — if you change the tasks, you are not running 75 Hard any more. You are running your pact. Call it what it is.
Side by side
| 75 Hard | Unbroken | |
|---|---|---|
| What it is | A program with published rules | An app that holds you to a pact |
| Who writes the rules | The program's author | You, or the published rules unchanged |
| Miss a task | Start over at day 1 | Run resets to day 1 |
| Who sees your days | Whoever you choose to tell | Your witnesses: partner or squad |
| History after a reset | Whatever you kept yourself | Banked days stay in the Record |
| Task flexibility | None by design | Full, and it is on you to write it hard |
What is identical
Midnight does not negotiate in either one. The reset is real in both. Neither the rulebook nor the app does a single press-up for you.
An app that congratulates you for logging a workout you did not do is worse than a paper calendar. The only thing that makes a tracker worth having is that the rule is fixed in advance and someone else can see the result.
Which to use
Use 75 Hard's rules if you want an external standard with no ambiguity, and you can genuinely find ninety minutes a day for eleven weeks. Start with the rules explained task by task.
Write your own pact if the published list does not fit your sport, your injury history, or your shift pattern — and then make it as unforgiving as you would have made theirs.
Use both. Running the published rules inside a tracker with witnesses is not a compromise of the program. It is the same standard, written down where it cannot be quietly edited, with someone watching. If you want the shape of the standard version first, the 75 Hard tracker lays it out unchanged.
If you are still choosing between programs, 75 Hard vs 75 Soft compares the two on workload and the failure rule.

Frequently Asked Questions
Can I do 75 Hard in Unbroken?
Yes. The published rules go in as your pact, unchanged: two 45-minute workouts with one outdoors, the diet with no alcohol and no cheat meals, a gallon of water, 10 pages of non-fiction, and the daily photo. Miss one and the run resets to day 1, as the program requires.
Does Unbroken make 75 Hard easier?
No. It makes the rule harder to dodge. The reset still happens, and a witness who can see your days is a stricter form of accountability than a private calendar. What it removes is the loss of your history, not the loss of the run.
Is Unbroken affiliated with 75 Hard?
No. Unbroken is independent and is not affiliated with, endorsed by, or sponsored by 75 Hard or its creator. The program is named here to describe it, which is all.
Why keep a record of days if the run resets?
Because the training happened. Research on progress monitoring found stronger effects when progress is physically recorded and visible to others, and a permanent record is what stops one broken run from turning into a month of nothing. The rule still bites; the history stays honest.
Do I need an app at all for a 75-day challenge?
No. A wall calendar and a pen have worked for a long time. What an app adds is a rule you cannot rewrite after the fact and witnesses who see the days as they happen — the two conditions under which tracking works best.
