Facebook’s answer to Snapchat. The twist is that before you can view a photo or video you’ve received, you’ll have to send the sender a shot of your own. After you’ve viewed it, the shot disappears.

Although the app comes from Facebook, you’re not required to have a Facebook account to use it; you can send and receive shots with people who aren’t your Facebook friends.

Anyone who knows your teen’s phone number or Slingshot username can send photos and videos to your teen. Users register for the app with their Facebook account or a mobile phone number, and the app will search your contacts for friends who have the app.

Unless you decline use of location services, your city, date, and time will appear each time you send anything from Slingshot.
