I can hardly imagine anyone sane developing an app on your own if you're not a professional programmer. My fitness trainer wanted to launch a remote training app during the pandemic and we discussed this a lot. He went through a number of tutorials but at the end of the day decided to outsource the development. He was talking to this team and liked their approach a lot. Unfortunately he failed to get funded, but the provider sounded very professional and it may be a good idea to talk to them if you're looking for oursourced application development.
