Resources for learning Kotlin to make Apps, have C++ experience

Hello everyone!

I’ve been interested in learning Kotlin for a while now, and have decided to the the plunge, and would really appreciate what you all might think are the best learning resources! I’ve been using the CodeCademy kotlin course, but so far it’s really just teaching me some light syntax use and basics of the basics of programming. I’d love any resources that also include some practice projects, like making a simple calendar, or an interactive clock app, or anything else that’s at least a step up from rudimentary understanding. Blogs worth reading would be interesting as well.
