Most people will learn kanji on their own and do like 10 per day, so 5 per lesson is super slow (you probably won't do a lesson every day). Ideally, you learn kanji a lot sooner than it starts it.

They spend so long teaching all the kana (where other texts will force you to learn it as chapter 0) that they end up delaying kanji. Seriously, if you're not supplementing yourself with other material, you'll find yourself a bit reliant on it. Speech within the app as well as sentence breakdowns (with translations) are nice for beginners to not feel so overwhelmed. Compared to Genki, I found the grammar was often explained more thoroughly.

The grammar is well planned out with a lot of examples and explanations to really iron it out. I think just the fluid, down to earth explanations are what made it super enjoyable. Compared to something like Genki, it feels less like rote memorization and more like you're in a classroom. The author does a really good job of explaining things. It's good, and I liked it, but there are certainly some things to keep in mind. I've never tried Lingodeer but I've used Human Japanese. They're both good apps, but they're suited for different learners with different goals. HJ will give you a pretty deep grammatical understanding of its material but moves at a slower pace because of it. The grammar explanations are also very, very thorough, especially compared to something like the Genki books which feel like rote memorization of key phrases in comparison. Human Japanese and HJ Intermediate (poorly named - both together will get you only to upper beginner level IMO) are textbooks that have been very slightly "app-ified." Standard textbooks with lots of text and example sentences, but with audio and quizzes built in nicely. I feel like it's better suited to people who are very casual learners (no outside goals like JLPT, just learning basics for fun) or to people who have passed early beginner level and just want to review. LingoDeer is a gameified study tool similar to (but far, far better than) Duolingo.
HUMAN JAPANESE VERSION 2.0 VS VERSION 3.0 FREE
LingoDeer when it was only free (didn't know they had a paid version now?) and both paid versions of Human Japanese.
