> Yeah I agree. Anki has a failure mode for me that I eventually accumulate >5000 flash cards and a review session can take an hour or more.

You don't really need to keep up with Anki's review sessions, even a partial session is very effective when you have lots and lots of cards. The tradeoff is that you might not actually maintain 100% recall of all items, but you'll recall most of them, and the scheduling algorithm will space out the items that you do recall even further.
