Sony today released the Timeshift Burst app, previously available as an exclusive to Sony Xperia Z1 users, on Google Play Store. Timeshift Burst is part of Sony's Social Camera apps suite, which allows users with compatible devices to quickly shoot 61 shots that are from right before you actually pressed the camera shutter, for a second after. Once done, you can scroll through the images and select the ones that you'd like to keep (i.e. the best one).
Owners of the Xperia Z, Xperia ZL, Xperia Z Ultra and Xperia Z Tablet can download the app from Play Store for free.
