Designing training for Mobile App

Hello! I've built several 'chromeless' interactions in Storyline in 9:16 portrait format that fill most mobile screens quite nicely, but they are not truly responsive. I also tend to use quite a high resolution (at least 1080p) and take care with font and button sizes to ensure readability and operability.

Some of these interactions look pretty good on a desktop monitor, but it really depends on your content and the interface. 

It's more work, but consider building your main course in Rise (which of course is responsive) and then linking to demo interactions in different screen sizes. For instance, a button set with a choice of 'Desktop' or 'Mobile', opening the demo in a new window or tab, taking full advantage of that device's screen size and layout.
