It is the best of its kind, it can even read PDF!
BUT BUT BUT
I can not use the 'switch language' at google translate permanent. For example if I want translate an english text to hungarian. No way to change it permanently. You have to always click on the 'switch language' button/text, then search for the 'target language'. I know this is focused on Japanese/Chinese language, but it is not a big change and a lot of new users can come to use this awesome app. Hope it will be upgraded.
(thx for the respond. It is a small change, indeed. Basically google translate uses the URL to change language. I think you could gain a lot of new users if you just put other languages like this.) Keep going, it a good app.
