I have a very simple idea for a phone app (basically a timer with notifications and a specific UI). But I have no idea how to do programming or make apps or anything like that. Are there any tools I can use to make this app without having to learn programming? Or if not, what is the minimum programming I need to know? (I tried to learn C++ once, and I broke Hello World--it wasn't meant to be.) Maybe some free online courses I could take for phone app design?
Thanks in advance!
