Keynote is one of the most underrated soft out there!
Easily my favorite tool for rapid prototyping. Supports video and gifs and triggering animations with defined clickable areas. The only downer is not being able to view your prototype on a device.
Hey Jordan, this is my process for getting prototypes on device:
Download the iOS Keynote app.
The iOS app is forced to landscape (unfortunately) so you have to make sure your presentation is rotated-- there are scripts out there that handle this automatically.
Transfer your presentations over via iCloud or iTunes.
If you want to learn more I explain this process and include the rotate script in the full course--you can check out the link in the tutorial. I don't want to plug it too much here.
Love using Keynote for animations!
Working on one now and just completed this: Material FAB Email
Just a heads up. You have Part 1 posted twice in your article instead of Part 2.
Thanks Jordan, just updated it.
