75 Hard App: What to Use to Track the Challenge

By the Habit Dungeon team · Last updated:

Quick answer

For most people a free browser tracker is enough for a 75 Hard app, because the challenge only needs six checkboxes a day. Pay for an app if you want reminders, photo storage and progress that survives a lost phone. The official app costs money and does the job; general habit trackers are more flexible afterwards.

Choosing a 75 hard app is a smaller decision than it looks. The challenge has six fixed daily requirements and one rule about missing them, so almost any tool can technically hold it — the difference between options is whether they help on day 50, when motivation is gone and the novelty of a new app has long worn off.

This page compares the realistic choices honestly, including the case for not paying for anything at all.

What a 75 Hard app actually needs to do

Six checkboxes, a day counter, and a rule that a day only counts when everything is done. That is the entire functional requirement, which is why so many free options exist and why paying for a dedicated app is genuinely optional.

Where apps differentiate is on the parts that keep you going rather than the parts that record you going: reminders timed to when things actually fail (water in the afternoon, photo in the evening), somewhere durable to keep 75 progress photos, and anything that makes day 40 feel different from day 39.

That last one is the real problem. The middle of a fixed-length challenge is a motivational desert, and no amount of checkbox design fixes it.

The realistic options

Ranked by what we would actually recommend to someone starting on Monday, with the trade-offs stated plainly.

A free browser tracker

— Best for most people
Platforms:
Any browser
Price:
Free

Our own free 75 Hard tracker is on this site, and there are several others. Six checkboxes and a 75-day grid, no account, no cost. For a challenge this simple, this is genuinely sufficient, and the money you do not spend is the point.

Strengths

  • Free, no account, works on any device with a browser
  • Nothing to install, nothing to cancel afterwards
  • Nothing about your diet or body is uploaded anywhere

Trade-offs

  • No push reminders — you need a phone alarm for water and photos
  • No photo storage
  • Progress is tied to one browser on one device

The official 75 Hard app

— Best for doing it exactly as written
Platforms:
iOS, Android
Price:
Paid

Made by Andy Frisella's team, so the rules are implemented as intended with no interpretation needed. If you want the canonical version and the community that comes with it, this is the straightforward answer.

Strengths

  • Rules implemented exactly as the program intends
  • Built-in photo capture and storage
  • Official community and accountability features

Trade-offs

  • Costs money for a 75-day use case
  • Single purpose — it stops being useful on day 76
  • Tightly coupled to one program's philosophy

A general habit tracker

— Best for what happens after day 75
Platforms:
Varies
Price:
Free to ~$40/yr

Streaks, HabitKit, Loop and similar apps will hold six daily habits without complaint. They are less tailored to 75 Hard, but they are still there in month four when the challenge is over and you are trying to keep two of the six requirements permanently.

Strengths

  • Keeps working long after the challenge ends
  • Reminders, widgets and statistics
  • Many good free options, especially on Android

Trade-offs

  • No built-in 'restart at day one' rule
  • Photo tracking is usually missing
  • You configure the challenge yourself

Habit Dungeon

— Best if the middle of the challenge is where you lose people
Platforms:
iPhone
Price:
7-day free trial, then $39.99/yr

Ours, so weigh this accordingly. It is a habit tracker built as an idle RPG: each completed habit powers a hero who runs a dungeon expedition that night, and the outcome is decided entirely by what you actually finished that day. It is aimed squarely at the day-40 motivation problem rather than the checkbox problem.

Strengths

  • Built for the boring middle, not the enthusiastic start
  • Never-miss-twice streak protection instead of hard resets
  • Parties and a weekly co-op boss for accountability

Trade-offs

  • iPhone only — no Android or web version
  • No progress-photo feature, so pair it with your camera roll
  • Paid after the trial, and it is not a 75 Hard-specific app

The honest recommendation

If you are starting 75 Hard this week, use a free tracker and a phone alarm. Spend nothing. The challenge is difficult for reasons that have nothing to do with software, and buying an app on day one is a very common way of feeling productive without doing anything.

If you have failed 75 Hard before, the thing to fix is not the tracker. It is almost always one specific requirement — usually water or the outdoor workout — and the fix is logistical: decide the time, the place and the container before you start.

Pay for something when you have identified a specific problem it solves. Photo storage, if you keep losing them. Reminders, if you keep forgetting the same item. Motivation architecture, if you keep dying in the middle. Those are real reasons. 'It looks nicer' is not.

Frequently asked questions

Is there a free 75 Hard app?

Yes, several — including the free browser-based tracker on this site, which needs no account or download. Free options generally lack push reminders and photo storage, which is the main reason to consider a paid app.

Do I need an app for 75 Hard at all?

No. A paper calendar and six checkboxes work fine, and plenty of people finish that way. An app helps with reminders, photo storage and not losing your record, but it is not what determines whether you finish.

What is the official 75 Hard app?

There is an official app from Andy Frisella's team, who created the program. It implements the rules as intended and includes photo tracking and community features, and it is a paid app.

Can I use a normal habit tracker for 75 Hard?

Yes. Create the six daily requirements as habits and track them together. The main gap is that general habit trackers will not automatically reset you to day one after a miss, so you have to enforce that rule yourself.

Which 75 Hard app works on Android?

The official app and most general habit trackers are on Android. The free browser tracker on this site works on any Android device too. Habit Dungeon is currently iPhone only.
