iKnow! Customer Insights

1. It's a good tool for vocab, giving you a mix of words on different subjects and in different contexts (sound only/kanji only /fill in the blanks /multiple choice etc) which means you can't just guess the word from the pattern of questions, which I find happens a lot in other apps.I wish I had found this app years ago.

2. I'm short before paying expect I wish I could type in hiragana instead of romaji characters! Update: meanwhile I subscribed, they are actively maintaining it and fixed the issue with the keyboard quickly! Awesome 👍Edit Update: Seven months after reporting clipped audio on the Samsung Galaxy 4 tablet, nothing has changed.

3. 5 stars.Love this app, I use multiple apps for studying Japanese, but this is my go to for vocabulary and even has great audio content.

4. October 2018 Post:The latest update is clipping off the audio from the end of a lot of sentences and verbs on the Samsung Galaxy 4 tablet.

5. The only thing I'd change is make it an option to be forced to type in each Japanese word instead of having it be random.

6. This app makes it so easy with the sentences! And having actual voice actors instead of Google voice is great.

7. You can piece together what is already provided, or supply your own words, sentences, audio, and images.

8. There's plenty of free tools that do the same, just look for them...It's a perfect app to learn Chinese in my spare time (which is scarce).

9. This app lets you access your content on the go, and has an additional study method for listening.I think its great.

10. It breaks the core 6000 words down in sections of 100 words for each step.

11. Would like it to have some polishing and perfecting, so it works for various fingers.Best japanese app I've used, in my opinion! The only app I've paid for for japanese.
