Get it started on github, if it's not monetized you should be fine. If you run into issues with google/apple oh well you had a learning experience. They said they wouldn't hunt you. Either way would be cool to have an app that got 1k downloads before it got taken down. I'd be willing to help, I'm good at android but dont have apple device so im locked out of iOS.
This class was pretty good just go through the tutorials https://academic.csuohio.edu/zhao_w/teaching/CIS470-S20/cis470.html If you need help getting started reach out to me on discord: Ray#9954. I really think its the kinda thing where once you get the jist of it you're rollin.
