Answer 1

You can sell your applications on various sites, on these sites you publish a project for any amount. But for me it is better to use the programming language.
You can program applications using languages: Swift, Java, Kotlin ...

• IOS - Swift
• Kotlin - Android
• Java - Android ana more...
