Here's the description of the app:
Slingshot lets you quickly share moments—little and big—with all your friends. Shoot a photo or video of what you’re up to and sling it to a bunch of people. They won’t be able to see your shot until they sling something back. Tap on a shot to react, or simply swipe it away.
• Stay in touch: Capture photos and videos of moments you want to share with friends
• Go shot for shot: To unlock new shots, first you have to sling something back
• Enjoy it while it lasts: Once you swipe a shot away, it’ll no longer be viewable
• Send a quick reply: After unlocking a shot, respond with your reaction
• Get creative: Express yourself with captions and drawings
• Look when you want: View unlocked shots later if you’re busy
The unique aspect of the app is obviously its requirement that you share something back in order to view something that has been shared with you. This may increase app usage, if it works.
