Yeah - I bought it a couple of days ago. It's a great idea, and seems really useful. I could see myself using this app a lot. The interface is very simple and nice to work with.
Pros:
- Simple interface
- Updated daily, can store already downloaded words for later study
- Includes a simple matching game where you match the meaning to the word (in Japanese)
Cons:
- Doesn't appear to be a way to stop the app from downloading data - BAD news for those on limited data plans like us poor Australians
- For some reason the matching game only works on the daily word list
- Not really a con, but the choice of words really stood out as being... "eclectic".
I think it's a good start for sure - A few things off the top of my head that I could think to improve it:
- Ability to select words from the word bank list to be used in the minigame
- Optional download of new words (customisable through settings etc)
- Sample sentences for some of the more unusual words / phrases
- Ability to send all daily words to the stored list with a single button press (honestly not sure what the app does if you don't store your daily words and new data is downloaded)
