Snatch

Snatch is a photo transfer app that uses physical hand gestures to transfer photos between mobile devices.
Snatch operates over any Internet connection (WIFI or cellular) and the GPS location must be enabled.

How to use Snatch? (see promo video for more details)
1. Select the photos you want to transfer
2. "Grab" the photos
3. You may either: a) "throw" the photos off your hand onto one or more devices; or b) "throw" the photos off your hand in the air, "grab" the photos, and "throw" them onto other devices.

Note: Snatch must be running on all devices for receiving/sending the photos.
