Encourages healthy eating and exercise, and monitors whether pre-arranged targets for both are being met. Targets that are met are rewarded by weekly payments of upwards of a few US cents, while failure to meet goals is penalised by sums of several dollars per missed target being withdrawn from the user's bank account (users who miss targets effectively funding those who reach them). Exercise can be monitored by the user informing the app about entering a gym. Workouts can be verified and logged courtesy of the phone's GPS and accelerometer. The app integrates with partner apps FitBit, Jawbone UP, MapMyRun, MyFitnessPal, and RunKeeper to help in fitness activities. Healthy eating is verified by the user taking photograhs of meals, which are then verified as suitable by other users of the app. The developer currently earns money by taking a 50-cent fee on each cash transaction (payment or 'fine').

Review: “It encourages monetary rewards for compliant users (those who exercise and eat well). Users can also lose money from using the platform. It is almost like bribing users to exercise.”

Review: “The Pact period begins on Monday, and runs through to Sunday at midnight. You make a pact that you’ll work out x number of times during that time period, and pledge a dollar amount that you will pay per missed workout. For instance, I do a 5-workout-a-week pact, so, anytime between Monday and Sunday, I have to complete 5 workouts. If I make 5 of 5 workouts, I get paid (yes, real money) per workout. If I only work out 4 days a week, I don’t get paid, I actually get charged the whatever amount I’ve agreed to pay per missed workout. Where does the money come from? Each week, Pact totals the amount of money from missed workouts, and puts that money into a pot. It is then divided between everyone who makes their pact. Some weeks, I get paid 0.25 a workout, others I get 0.50. Totally depends on how many people hit or miss their pacts. How do they verify if you’re actually working out? There are several ways. You can check in at a gym, and stay there at least 30 minutes (they are also great about allowing you to add gyms); you can do a run, or walk, via RunKeeper, and it will sync to Pact; or you can use their motion tracker for home workouts (I usually just wear my phone in an armband, and it picks up the motion while I workout). It’s definitely not a get-rich-quick scheme or anything, but it motivates me. I started using this app a little over a year ago, and I’ve already taken out $85 (and used it to buy some lululemon workout gear). Now, I’m back up to over $60. Yes, it took a while, but free money is free money.”
