Recommended courses for a Mobile App Development and/or Design class

Any recommended units/courses for a Mobile App Development and/or Design class?

Thanks!

I’m not sure which grade level you’re working with, but this curriculum worked well with my 7th graders and I know others who have used it in 9th & 10th as well: Event-Driven Programming in App Lab - Code.org

First off, much love and appreciate you sharing your experience!
I have high school (9-12). Would this suffice?
Thank you again!

You could definitely use the Event-Driven Programming curriculum with HS students. You might also take a look at the Computer Science Principles curriculum too. This is geared specifically to high school students.
