Anki can be difficult to set up, but it really depends on the deck.
My advice is actually to make your own deck. These premade ones have no context and a lot of the content tends to be forgotten later on.
I actually replied to a post yesterday about it
My advice would be to make your own so it is more meaningful to and only put stuff in there that you learned somewhere else.
When I first started I was doing 3 different srs and to be honest, it was too much and didn’t help me in the long rung. I think slogging through a grammar book and then using native content afterwards.
My advice for your genki journey would be to make the cards yourself because it will help you to remember the words.
Alternatively, Kitsun has much better Genki decks than anki although it’s about $7USD a month I think.
They are similar to the WK layout so it will be more familiar to you than the anki equivalents
