Very (very) random, but I want to show you what I (re)build in the last 3 years using kotlin.
To be honest it was a joy using kotlin all the way and I am not sure if would have done it in Java.
Its my little math-app 'x=1: Learn to solve equations!'

Which is my passion project (so no adverticement / payed products involved).
If you want to have a bit of fun with (seemingly) unfunny math, give it a try!
From a developer standpoint what stood out the most is that there were no need
for big migrations relating to kotlin in these 3 years.
Every new Kotlin-Version was a breeze to use.
Just a huge thanks to the jetbrains team and the whole community for 3 years of fun coding in kotlin!
