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
Put a price on every miss
Choose what one missed session costs you and pick a charity you care about. Your card is saved, but nothing is charged unless you miss. The app shows the most you could ever pay before you start.

03
Prove it. Every time.
Submit a photo, a screenshot or a GPS check-in. Every session you do costs nothing. Miss one and that session's price goes to your charity — after three days in which you can contest it. 9% of each payment keeps DoOrDonate running.
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.
