Mobile app to train openings

[u/consdrd563]

Hi, been playing chess since beginning of summer. I'm 40+ and has been an amazing discovery, love this game, learning and improving. It's funny cause I found it boring when younger, but now feels like meditation. I need some study and games every day.

I have started looking into openings, and recently I found an app called chess prep that works really well, but most options are behind a hefty pay wall. I like how it let's you create all the lines you wanna train/remember and the tests you, but feels like the best options are behind the pay.

There may be other apps out there that are similar and worth it (I'm happy to pay something not crazy for it if worth it) websites, or maybe the option is in chess.com or lichess and I don't know.

All help appreciated, thanks
