Xamarine -Microsoft Cross-Platform Mobile Apps Developer Tool
Xamarine is based on MS Visual Studio to build both IOS and Android Mobile apps with the same codes in C#.
Caveat is the language is C#, slightly less verbose than Java, not functional programming like Kotlin or Scala.
Explore Xamarine / C# if you are from the old Object-Oriented school of programming.
If you are a Mac user, then sorry Xamarine/Visio Studio/.Net / C# only run on PC Windows.
