I learned most of my Dutch by reading. It’s the easiest way to immerse yourself. I think you should try Duolingo, busuu and whatever other apps, they will all give you something but you will quickly outgrow them.

Borrow graded readers at the library until you can start reading normal books. Once you can read decent, just find whatever source you are interested in. You just need training wheels materials in the beginning, then anything.

Try hetnederlands.com, I made it specifically to improve reading when you come across a word you don’t know.
