Boomerang from Instagram
is a video app that lets you turn your photos into fun and dynamic short videos. To use the app, simply shoot a burst of photos, and Boomerang will stitch the photos together into a high-quality mini-video that lasts just over two seconds. Videos can be played both forward and backward, and will loop for however long they're being viewed.
Use of Boomerang for iPhone requires iOS 8.0 or later. The app is also compatible with the iPod touch.
Boomerang from Instagram for iPhone is also available on Android
