I find that srs is not quite enough for me to learn things so that I can recall them totally automatically and with no uhm-delay.
However after the normal wanikani reviews, I’m tired of clicking, tapping and typing.
I’ve come up with my own little method of reviewing very rapidly and effectively, which is an adaptation of something I used to do with pen and paper and I wonder whether any of you does the same.
I do my reviews on my laptop and I’m not sure whether this would work on your mobile.
I select a level from the top menu.

I make my window narrow and tall and I zoom in to 250%.

I then start at the top and I work my way down the list recalling meaning and reading. (If you find it difficult to blank the answers on the right, you can always cover them with another window or even with your hand or a book)
If I’m hesitant or I cannot remember a few of them, I start all over again until recalling meaning and reading is fluid and effortless. Sometimes I only repeat the kanji or vocabulary section.
The first time takes only a couple of minutes.
I only wish that pitch patterns and audio buttons were also there.

Do you use the same method to supplement your reviews?
