Pact is a free app that keeps you on track to work out, eat more veggies or log your food by putting money on the line. You choose how much to put on each Pact that you make. If you perform the tasks you promise to do, you will earn money with the app - from $0.30 to $5 a week.
This can add up over time. Since joining Pact in 2012 Zach Bingham earned roughly $500, and lost $40 by doing the same workouts he had been doing before he started.
But if you don't keep the pact, the app will debit your bank account for the money you put on the pact. You can start with a small amount, or up the stakes to keep yourself motivated to eat more veggies, work out or just log your food.
