I've gotten into chess for the past year, and while I used Lichess for a little bit, I wound up going with chess.com primarily instead. The app is great. The learning modules are really helpful, and I love the puzzles.

It also has tens of millions of users on the platform, so your matchmaking is going to be more accurate, whether you need to be matched with opponents who just learned how the pieces move, all the way up to the top professional players.

As for outside resources, I've been mostly learning from random masters/GMs that have youtube channels.
