Said and done. Stop procrastinating: for when you know what you want to do, but you don't do it.

Because a promise to yourself costs nothing to break. With a guarantee, it does. And getting it back when you keep your word is its own reward.

You lose what you put down, not a cent more, and tomorrow is another promise. There are no streaks to break and nothing to start from scratch.

If the fault is ours, you're not charged anything. And if something real comes up, you dispute it and a person from the team reviews it.

You can choose a different guarantee: if you don't follow through, Ultimatum blocks the apps you choose, like TikTok or Instagram, for a few days.

Nothing a month: there's no subscription. You only pay if you don't do what you promised, and you choose the amount.

No. The amount is only held on your card, like when you book a hotel. If you keep your promise, the hold disappears and not a cent moves.

You're charged what you chose when you promised, not a cent more. You decide the amount before you start: €0, €5, €10 or €20. With €0, what's on the line is your apps.

A photo taken in the app before the deadline, showing what you wrote when you promised: breakfast on the table, you at the gym. If you like, you can add a location check.

No. The camera only takes photos in the moment, with no access to your gallery, and checks the depth of the image to rule out photos of screens or prints.

You dispute it from the app within 48 hours and a person from the team reviews it. If you were right, we give you your money back.

Yes, but the deadline doesn't move. You can sleep five more minutes; the photo still has to arrive in time.

Anything with a time that you can prove with a photo: getting up, going to the gym, running, studying. A single day, several times a week or a whole month.

First on iPhone, in Spain. Joining the beta is free and we'll let you know as soon as you can try it.
