The beta version of Alight Motion is still available, but you can also try it out for free. This is a true motion design / compositing program that runs on Android. And with it actually on many smartphones.
We tried it once and were positively surprised at how the manufacturer managed to develop a coherent operation that can actually be combined on a small display layer and controlled with keyframes. For moving points, for example, there is a kind of virtual touchpad. And instead of moving the timeline, you move clips around a central marker to conveniently set keyframes, among other things.

Also remarkable is the real-time performance on a mid-range Moto G5, even with an embedded video including keying. The only question that remains is what a pocket-compositing environment can be used for? Probably primarily for prototyping your own ideas on the road. Because despite good operating ideas, one should come on a PC/Mac with the mouse and keyboard in front of a screen clearly faster to comparable results.
Nevertheless, Align Motion is an impressive app that may find even more use on larger Android tablets. The developers also call for concrete function requests during the currently open beta phase.
