Take a picture or a selfie and send it to a friend, or several. Their front-facing camera captures a "stealthie" of their reaction as they view it, which they can send back to you, along with your original photo!

You can keep playing and building up stealthies until one of you stops the game - at which point, all stealthies in that thread are deleted.

If the first stealthie that the app captures is just too bad, you have one chance to retake (using the front or back camera) but the sender will know that it's not your original stealthie!

Nominate your Facebook friends to join Stealthie by sending them a photo from the app. Once they sign in, they can open your photo and, to be initiated, they post their stealthie on Facebook.

Only nominations can be posted on Facebook - all other stealthies are for the recipient's eyes only and are deleted as soon as they are viewed if the recipient does not want to play on.
