Countless times I’ve set an alarm with the intention of hitting the gym before work, only to repeatedly tap the snooze button until it’s too late. A more attractive option is Pact — an app that offers a financial incentive for your exercising efforts. Simply select a health goal for the week, whether it’s to go running, visit the gym or eat healthier foods — along with how much money you’re willing to put on the line. Throughout the week, you’ll log your activities — checking into the gym using GPS, tracking walks using your phone’s accelerometer, or taking photos of meals that will be verified by other users. If you manage to achieve your goal at the end of the week, you’ll receive a financial incentive sourced from those failing to meet their target.
