@788166676 We’re working on auditing and improving the decks and just released an update for the JLPT N1 deck a couple weeks ago. But in the meantime, you can always create or edit your custom decks Skritter already has kana equivalents of many kanji words in its database.
Our official lists need to cater to all levels of learners, and our specialty is efficient character memorization, so our content tends towards Japanese as it is generally written adults. As @thomas1985 can probably attest to, on the Chinese side of things, there’s not much a learner can do to avoid encountering large amounts of hanzi after their first few days of learning onward. But we on the Skritter team recognize that Japanese does present a different possible path for easing new learners into the language that Chinese does not offer, and it’s something we want to explore more in the future.
