Pact, formerly known as Gympact, is an app that you use to wager money on whether you’ll go to the gym or complete a workout. The app verifies if you’ve hit your goals by making sure you check in to the venues where you said you’d pump some iron. If you reach or exceed your goals, you earn cash. If you don’t, you have to pay up. The pot is communal, and there are a lot of slackers out there pouring money into it.
