Sneaky is a fun app to snap candid photos of your friends using their camera.
Once you are logged in you can invite your Facebook friends to get Sneaky with you. This means when your friends approve your Sneaky invite, you can snap photos of them.
Snapping a Sneaky pic triggers your friends camera on their phone and returns their location and photo. The more Sneaky photos your friends take of you, the higher your score.
Have fun and go get Sneaky.
