JA Sensei Customer Insights

1. I've wanted to learn Japanese for years, and this app has been the best resource I've found so far.what a great learning program for just under $13.00!! Also, I bought the samurai life membership from the website for roughly $50.00 USD... This is the best way to learn, along with JA Audiobook.

2. There are numerous resources in one place, and if you do purchase the upgrade, it has a more than fair price for lifetime access.Wow, I wish I'd downloaded this first when I started learning Japanese! All the grammar and syntax and such are laid out where I can easily read them and take a quick quiz, instead of having to listen to someone explain things or watch a video.

3. Then you throw in the vocab lists, conjugation, aural comprehension, and more, and you've got a veritable smorgasbord of Japanese learning.Crazy comprehensive app! Explanations for everything and though there's more than enough free content, I do Google Surveys and that paid for the downloadable content.

4. It is easy to use, has various modules for different ways of learning, is written clearly with great examples, has various quizzes, flashcards, etc to reinforce learning, is reasonably priced...the list goes on.

5. That really helps me to process at my own pace! Still a little fuzzy about what to do with "points," and a little overwhelmed by the sheer number of things to explore, but overall, I'm impressed!Great for self-learning Japanese.

6. I love how the lessons are structured! They make a ton of sense and add in cultural facts alongside learning the kana and vocabulary.

7. JA Sensei is one of the most detailed and helpful applications to help you learn Japanese.

8. Easy to search and find verb conjugations, adjectives, kanji, and even counters! Irarely use my Japanese dictionaries anywhere.

9. There's also the ability to do lessons on a computer, but I prefer the app myself.I think this is an amazing app for a dedicated student interested in learning quickly.

10. I bought the Samurai Unlimited and can't finish learning all JLPT N3 vocabulary.

11. If you struggle with any sort of learning disadvantages, the layout may not always be friendly as it can be both over and under stimulating.
