What program to choose for animation of mobile interfaces?

Question

User interface

What can you advise for working with animation for mobile interfaces? Preferably with a low threshold of entry. I started to learn Pixate, but it's terribly complex and my head is just bursting at the seams. Same with facebook origami. There is very little documentation and tutorials, I have been standing still for a couple of months. First of all, they are interested in programs in which you can make such a prototype that the customer can twist, so to speak, in his hands, in his iPhone, and it is desirable that there is also a code at the output. I am not interested in any After Effects in principle, since I do not work for likes on dribble. I will also be very grateful to any tutorials on the same Pixate and Origami, well, and all kinds of advice on this topic.

Answer 1

Origami is now updated and they say SketchUp + Origami - ok. Keynote is often underestimated, and in vain. PaintCode will help generate the animation code, but not the app itself.

Answer 2

www.relativewave.com and framerjs.com for mac only,
www.invisionapp.com and https://marvelapp.com/

Answer 3

Thank you. It’s hard for me to really get into Origami, it’s like a helicopter and there really isn’t any documentation :(
