GymPact encourages people to go to the gym through positive reinforcement (getting paid when you go) and negative reinforcement (getting fined when you don't).
Users set the schedules they want to stick to, and log workout hours by checking in at their gyms on the GymPact app (locations are confirmed by smartphone GPS tracking).
Those who don't meet their goals pay $5 for every missed workout. Then the money is pooled by GymPact and paid out to those who meet or exceed their goals. You'll never skip the gym again if you use this app.
