What our users say about us

Very usefulIt's, quite obviously, useful in a great number of different ways. Spell checking and definitions clearly being the top of the list. The pronunciation assistance has been the most useful one, though, for my family. We have (myself not included - I just watch and listen) arguments and disagreements over such that have, in the past, lasted for months! So, yes, this is nothing less than perfect for those in need of a dictionary service.

Essential for teachingThis is an awesome dictionary!! Being a teacher, I find the Oxford Dictionary absolutely essential and fantastic to use!! For a very small amount of money, I paid for the Pro version, and I truly don't regret doing so!! I love the authentic-sounding audio, as well! Terrific indeed!
MBMark Bevan
Perfect for language learnersMy favourite dictionary app so far. As a language student, it's very useful for me to have the words' multiple meanings' and examples. Though it would be even better if it were accessible while offline, but that's okay, I've never had a huge problem with it. I even have the dictionary book itself in hand, but it's hard for me to find the words one by one, so this app is a lot easier and more useful. I would recommend.

Smartly linked definitionsI like that in the definition of a word, I can tap on other words I don't understand to see the meaning. Furthermore, it returns to the previously opened definition when I hit back. The price that's less than 2000 yen for a one-time purchase is also a plus.
