Frequently asked

Questions, answered.

Is the 75 Hard Tracker free?

Yes — completely free, no ads, no premium tier. It's a personal project. You only need an email and password to sign up.

Can I customize the 75 Hard rules?

Yes, and this is the main reason this tracker exists. Before you start a challenge, you can edit, add, or remove daily tasks. The seven standard 75 Hard tasks (two workouts, follow a diet, no alcohol, gallon of water, ten pages of reading, progress photo) are pre-filled if you want to follow the original. Once you start, the task list is locked for the duration so you can't soften the rules midway.

What happens if I miss a day?

You decide. There's an explicit "I missed a day" button that resets the challenge to Day 1 — that's the strict 75 Hard rule. Alternatively, you can end the current attempt and start a new challenge with different rules. Failed and abandoned attempts are archived in your history so you can see your full journey.

Does it work on mobile?

Yes — it's a mobile-friendly web app, works in any modern browser. On iPhone you can tap Share → Add to Home Screen for an app-like experience.

How is this different from other 75 Hard apps?

Most 75 Hard apps strictly enforce the original rules. This one lets you set your own daily tasks at the start. Want fewer workouts, different reading goals, or a 30-day version? You can. Want to follow the standard challenge exactly? The defaults are already set up. The customization is the differentiator.

What about a progress photo or alcohol — are those tracked?

Yes, both are separate checkboxes in the standard task list. We split "follow your diet" from "no alcohol" because they're distinct behaviors, and treat the daily photo as its own item. You can remove either one if you don't want to track it.

Do you store my data? Is it private?

Your account and challenge data are stored in DynamoDB on AWS. No ads, no data sold to third parties, no third-party trackers in your browser beyond standard performance monitoring. The source code is available on GitHub.
