I haven’t actually timed myself, but I believe I’m spending over two hours a day on language learning, maybe leaning closer to three some days (I’m also currently unemployed and am no longer in school, so the time I’m spending on languages is replacing that). It’s spread out throughout the day, though, so it doesn’t feel like a lot until I add it all up!
I don’t think I spend more than a combined hour on WaniKani and KaniWani most days. According to the heatmap script, I average about 70-100 reviews a day on WaniKani (and I feel like I do generally half of that on KaniWani currently), plus 10 lessons. I do all of my WK reviews two to three times a day, which typically amounts to 40-50 in the morning, then the rest before I go to bed.
I’ve also been spending a half hour or more on other things, like learning how to write the kanji that I’m learning, and watching one video each day from the Japanese Ammo with Misa absolute beginners playlist.
Additionally, I’ve been spending at least an hour on Spanish. Maybe 10-20 minutes on Duolingo daily, plus an hour or so of reading a novel in Spanish. Eventually, I’m going to replace this time with reading Japanese materials, but for now, I’m getting into the habit with a language I’m more proficient in (since my Japanese isn’t far enough along yet for me to be able to read without a lot of struggle).
