There is an iOS application, it is a freeze-frame animation software. On the App Store, the most similar application performance is relatively poor, iStopMotion for iPad is an exception. It provides a rich set of features, you can see the implementation of each frame of animation superimposed and playback, view point in time and fine-tune for shooting clay, toys, animation, and also supports uploading to iCloud. The most important thing is the iStopMotion generated animation is very good, and the cost is $ 5, however, so it is still worth a try.
