Ratings and reviews

Awful. No way to lookup kanji. Search returns very random entries. I typed in both "7" and "seven" and it wouldn't even give me the entry for 7, much less the kanji. The other tabs are just shortcuts to an embedded Google browser tab, so if you already have a web browser on your phone (which you do) you don't need this app.

Pros: + Can scan photos + Both JP only and EN<->JP dict Cons: - UI could be improved a bit, but you find everything you need (very minor issue) - Everything is online: Photo scanning, Video advertisement and even the dictionary is online, so the app requires quite a bit of mobile data if used outside.

This app is one of the few Japanese dictionary apps on Android that features a monolingual Japanese dictionary - this alone makes it worth it for intermediate to advanced learners. The OCR and drawing input also make lookups smooth. Minor niggles include some annoying ads (which can be removed for a cost) and the fact that sometimes I've found the app will switch back to English for no discernable reason despite having it set to Japanese
