Sony Xperia Z1 is one of the best phones nowadays. An awesome camera, display, performance, its thickness... It also brings a lot of cool features such like MotionShot which captures a video of a moving object and creates a beautiful "moving photo" by putting all these captured frames into one frame.
This app has been ported and should work properly on all Android devices running ICS and above.
And how does it work? You just press the recording button, record the moving object (your kid, for instance), wait for the render and you're done with a beautiful piece of photo:
You can set the final resolution of the photo and even frequency and number of the photos. All you need to do is to press the recording button and don't move with your device while recording. While recorded, the photo will be created automaticlly.
The app does not require root access to work.
