How it works

Three steps.
No excuses.

Simple enough to start today. Consequential enough to actually finish.

1
01
Pick your challenge
Any goal you've been avoiding — go to the gym, cut social media, read every day, wake up earlier. Set how long and how often. The app tracks daily proof.
2
02
Stake what you're willing to lose
Choose from €10 to €100 and pick a charity you care about. Your card is saved but nothing is charged — the stake is only real if you miss a proof. That's the whole point.
3
03
Prove it. Every day.
Submit a daily photo or check-in. Complete every session and your stake is returned in full — we keep nothing. Miss one — your stake goes straight to charity. No exceptions.
Willpower
runs out.
Money doesn't.
Loss aversion
We work twice as hard to avoid losing €20 as we do to earn it. DoOrDonate turns that psychological bias into motivation — for you, not against you.
Meaningful failure
When you fail, your money goes somewhere real. That reframes the consequence — it's not wasted, it's donated. But you still want to win.
Daily ritual
Submitting proof every day builds the habit. The act of documenting progress is part of the design, not just a verification step.
