Ive been using the online resource learning Japanese by Tae Kim, and found it difficult to learn the memorization skills I needed to remember it using just the website. I looked around on the site and found a suggestion for this app and its been great so far! Its really helped me memorize phrases and kana, and helps keep my studies regular as well. Even the free version is super helpful!
