can i make a app in unity?

Hey guys i want you idea and help. i want to make a easy app, i am a betadvisor and i want my own app to win something more. what platform should i use to create, note : i dont know to program!

Thanks

If you need graphics in your app use unity, if not,
you can learn C# and learn Xamarin.Forms for cross platform: android,Iphone(if you have a mac), and window phone(Mm forget this platform, will dead soon).
Or learn Java and program in android studio etc…
