How it works
Choose a weekly habit or a one-off goal with a deadline, then set your stake.
Weekly habits are counted every Sunday night, and all your missed days become one payment. If you promised five days and did three, you pay for two. We warn you that evening, so you can still check in for anything you did. One-off goals charge once if the deadline passes unfinished, with a reminder the day before.
You pay nothing unless you miss, and thereâs no subscription.
You can also add up to five friends. They get a weekly email on how you did, which can be scarier than the money.
Where your money goes
You choose GiveDirectly, the Founders Pledge Climate Fund or the EA Animal Welfare Fund, and decide how much of each fee we donate, up to 100% after payment fees and taxes. Whatever you leave goes to Euzoia.
One honest detail: legally, what you pay us is a service fee, and we make the donation. So you wonât get a donation receipt, and taxes may apply.
How Euzoia compares
There are good apps doing this, and some will suit you better than Euzoia. Hereâs the honest version, based on their public pages on 6 November 2026. Prices can change, and I didnât test every plan.
Beeminder is the one for data lovers, and the app that inspired Euzoia.
You plot progress on a graph, and dozens of integrations can report your data automatically.
Itâs free for three goals, with paid plans from $8 a month.
Pledges climb after each failure: $5, $10, $30, $90 and up to the cap you set.
A paid plan can send half of your pledge to charity.
Forfeit is the one for people whoâd cheat.
AI or a real person reviews your photo or video proof, and it can read Apple Health, GPS and Screen Time.
It can also block distracting apps, and you can appeal to a real person.
It costs $10.99 a month in the US, on top of what you stake.
For now, lost money is âretained by Forfeitâ.
stickK is the original, launched in 2008.
You can name a referee whose verdict is binding.
You can pay an anti-charity, a cause you dislike, if you fail. stickK deducts 50% of those stakes.
Its 2024 terms say new charity and friend recipients were removed, but its App Store listing still shows them. Check before you commit.
Commity is the one for showing up somewhere, like the gym.
GPS confirms youâre actually there.
You can win back part of a lost stake, and on Premium ($4.99 a month) the rest goes to a charity you pick.
Itâs early, showing 82 members on its own site.
Accustom is the one for crypto users.
You lock your whole pledge in USDC before day one, and reviewers check your proof.
There are no grace days, and forfeited money goes to Accustom.
So which should you pick?
You love data and automatic tracking: Beeminder.
Youâd lie to a simple app: Forfeit, or stickK with a tough referee.
Your goal is turning up at a place: Commity.
You want it simple, and you want a slip to do some good: Euzoia.
Hereâs what Euzoia doesnât do. Thereâs no proof step or automatic tracking, so it runs on your honesty. Itâs a web app you add to your phoneâs home screen, not one from an app store. It has two commitment types and very few settings, on purpose.
Questions
What does it cost? Nothing unless you miss. Then you pay the stake you chose.
How much should I stake? Enough that youâd be annoyed to lose it, but not so much that you delete the app.
Is it tax-deductible? No. Legally you pay us a service fee, and we make the donation.
