I develop for Android since 2011. Since 2016 I also do more iOS. I mostly regret not looking into new developments faster. Things like Kotlin and Architecture Components. They are great, so at least experiment a bit with them to see what all the fuzz is about. Try to keep up!

Also, I wish I realized that Google Play is giving you a lot of stats and data about your apps (store) performance these days, which in most cases can help pinpoint a issue with your reach/growth.

I also regret everything about Objective C ;)
