I've been meaning to get into turning my UI's into working prototypes for a while now. My main issue was finding something that works well for me and my workflow as there are so many out there.
After trying out After Effects, Framer, Marvel and many others I've actually found @Pixate to be my favourite.
I went from not knowing how to use Pixate at all to creating this UI in a matter of 4-5 hours.
The fantastic thing about Pixate is that it actually works with input on the screen. So there are no illusions here. The UI responds to me tapping in areas where I've specified.
Note: Pixate haven't paid me or ever got in touch with me to mention their service. I genuinely find it a very good tool for creating interactive UI prototypes.
