One does this even exist and if so, how in depth can you make an app using one of these systems. Because as much as I'd like to build one completely from scratch, I only have the most basic of programming knowledge in C++ and that was only the most basic of programs where were all text based. And I might mention about 5 or so years ago and I haven't touched it since. And keep in mind that I'd like to make something for both Android and IOS, kinda excluding windows since I think the number of people who use that platform are so rare it wouldn't be worth it. What I'm looking to make isn't all that complicated, maybe some outside data support from places like National Weather Service or something similar.
