Android: Need a little motivation to make it to the gym? With Fitsby, you can think about the money your friends will wave in your face if you skimp on your workouts. The app lets you wager with friends that you'll work out regularly.
The basic idea is the same as previously mentioned Gympact, which also launched for Android last week. Some Lifehacker readers were concerned about putting your money where your workouts were when it came to strangers who might exploit the system; Fitsby eliminates that problem by connecting you with your friends and letting you all pool your money together for a group challenge.
You can challenge other users of the app or participate in public challenges if you want, but the app is best when used with a small group of dedicated friends who want to support one another's workout and exercise goals. You still have to check into an approved gym or exercise centre for the app to work (the service uses a location's name in Google Places to verify that it's actually a gym, fitness centre, or other appropriate location), and if you win, your friends' money will be sent to you via Paypal. For more details on how the app works, check out the FAQ. Fitsby is free, and currently only available for Android. The developers say an iOS version is on the way soon.
