Great, but...

They need better quality control and review of lessons. There are third party lessons and lessons developed by memrise. Its hit or miss.

Memrises own Japanese lessons are not good quality. They decided to incorrectly use hiragana as a substitute for katakana. Such misteaching is carried throughout, until the end of Japanese 3, at which point you graduate with much mislearning. The lesson designers were too dumb to see the consequences of that and failed address that problem in the lessons, sticking with their mistake the whole way through the course.

It would be nice to have a setting for larger fonts. I cannot see the small kanji in the grey box.

Pictures would be awesome.

Meet the natives feature is good.

I use iPad horizontal view and Memrise now accommodates that.

Many examples and questions are just wrong. Example:ー

これは私のお母さん。

ー これ is never used to refer to people! For people, it should be この人. And お母さん (okaasan) is not used when referring to ones own parents (RyanKeene44, et al).

The use of "okaasan" and "otoosan" to refer to ones own parents is wrong. "Haha" and "chichi" are correct. That is just one of many incorrect examples that are drilled in repeatedly, brainwashing the student with egregiously wrong information on language fundamentals.

Some examples have up to four repeat identical answers -- thats pointless.

If the expected answer is to be typed "moon; month" and the usee types "month; moon", it is marked wrong by the application, and that is wrong.

If the meaning of the kanji is "color" and you typed "color" you got it wrong; they want you to use the British spelling "colour".

Misinformation and wrong teaching is harmful. Memrise learning format is fun and engaging. With high-quality questions and answers, it would be a lot better.
