I find that combining WK with BunPro works really great. The latter can be used to both pick up grammar and to practice WK vocab in context (you can sync WK items to BunPro with an API key). And then, I feel like WK mnemonics are the most powerful way to memorize stuff, allowing me to recall items long after I encountered them last time.
Also, apologies for the shameless plug, but I made a lightweight web app to practice WK context sentences via listening to the TTS-generated audio: TTSensei web app: listening to randomized context sentences . Hopefully, you may find the app useful to add some context to WK items.
(Disclaimer: I’m learning Japanese for fun and with no particular purpose, so my way of learning is likely not the best)
