A pledge is money you promise to pay if you don't finish a task by its deadline. It's there to help you follow through.
Needs the Accountability Pledge feature.
Making a pledge
Swipe a task left and tap Add Pledge, or open the task and tap the Pledge pill.
Set the amount and the deadline.
Confirm.
Once a pledge is made, it can't be changed or removed. That's what makes it work.

Paying
If you miss a pledge, the amount is added to your balance. Paying happens on the web: tap to pay and Marvin opens the web page in your browser. You can also save a card there for automatic payment.
While you owe $1 or more, you can't make new pledges until you pay.
