Human Japanese 12+

With language apps, I believe competing on features isn't the most important thing - it's the style of the teaching, the quality of the explanations and the order of new concepts that matters.
The HJ writer is very articulate and strikes an excellent balance between casual phrases and grammatical explanations accompanied by ideas on how to link the two. I find a lot of other language learning material can lean too far in either direction. Reasons for certain language constructs are explained, but there is always an everyday context given alongside.
In addition, the features that HJ has are very nice and complement the raw content, rather than overshadow it (unlike the few "game" based language apps I've tried). The summary quizzes are succinct, and the ability to tap on almost any piece of text and hear it spoken aloud is very convenient. Almost every sentence allows you to drill down by word and view a short dictionary definition - very useful for when you recognise a word from an earlier lesson but can't quite recall the meaning (and saves either pulling up a third party dictionary or trawling back to find the previous lesson).
This a really great learning resource and the pacing is just right. Highly recommended.

This is the 6th app I tried in my search for a Japanese learning experience, and definitely the last (obviously I’m continuing with the next app in the series). Excellent progression of lessons, nothing too hard for my 50+ brain to understand. Sadly it took me over a year to really master, as I’m a perfectionist and won’t move on til I’m confident I’m up to speed on the current lesson, even including a review of previous lessons if they were hard. My only slight problem was the American slant on the ‘English’ used! Makes us real English have to think a bit harder 🧐. It would occasionally be nice to be able to exchange messages with a real person to get a deeper understanding of the use of some words and phrases.
Overall though, the best and easiest app of it’s kind. Thanks to everyone involved for easing me into this fascinating language and culture!

The other reviews are a few years old, but it’s still a very good resource. It’s like having a textbook on your phone instead of lugging around a massive pile of paper, and thanks to being digital it also has a lot of voice acting. Almost every Japanese word can be tapped on to play a native speaker’s recording, the only ones which can’t are the ones used in the middle of an English paragraph about grammar using an example, however there is usually a clickable version of that sentence nearby.

For vocab lessons I suggest taking the words and putting them into an SRS app to make sure you keep revising them. Human Japanese does have native flashcards but they’re multiple choice and not srs, so they aren’t perfect, however it’s not a flashcard app so I don’t think this is something to lower it’s rating for.
