You should start by choosing a patform and an app to build. Practice makes perfect. If ur phone is on android than start building a copy of an app that u like in Kotlin or if ur phone is Iphone then start building that app in swift ( you do need a macbook laptop or pc to develop in XCode). I was a total beginner at the start of the pandemic last year in march. And since then i learned on my own how to program in java, kotlin , swift ,node and javascript. That means almost 10 months of learning, deleting the whole project and starting again from scratch and finished building my own app and im going to launch it next month. But again practice pratice practice. Im not a professional developer atm but im at least mid level now. So for Kotlin u can use Android Studio or Intellij Ideea software and for ios is Xcode. Also there are loads of tutorials and help on google and youtube. You just need to start and write your first code.
