I had duly purchased as many as two dictionaries via the stupid diodict + n (n=1,2,3, ad nauseam) system. The purchased ones wouldn't open, showing just a pop-up message to download Diodict3, which was not even on the Play Store except for Diodict + (no serial number). So, I had to download it but quite embarrassingly the new Diodict asked me to purchase the same dictionaries again. Explain to me what happened with the old system.

I paid for multiple dictionaries on the app (Diodict 3, 4, etc) and then they relisted it with a new Google Play ID, bricked the old ones and demanded payment again. These products are not cheap. This is, quite simply, fraud. If the company comes clean and honours purchases, I will remove or edit this review. However, if you can read this, do not trust this company.

Compared with the previous Chinese Korean, Korean Chinese dict I still prefer the previosu version. Previously was very intense, so useful and user friendly dict apps (was the best Korean Chinese dict ever). However now too simple n not as much as information as before. Still, I m fans of diodict no matter how I ll used it for my language study.

Doesn't allow copying, even the headwords?!? Searching again multiple times is not possible too :) Not a beginner friendly dictionary app... I don't recommend this to non-native speakers. This dictionary tries to make things complicated.

Please be very carefully when using this app, it forcefully asks for PHONE CALL DEVICE AND CONTACT PERMISSION. Why does a simple dictionary ask for it, you need to copy my contact for ads, or any else suspicious purposes, like china phones? I will not use this app untill it have correct permission.

1. The versions of the Oxford Dictionary, the Collins Dictionary and the FLTRP Dictionary are quite old. 2. A decent color scheme, but chaoic formatting structure. eg. OALD.

False indications and representations, the dictionaries are Not Free And the one that is! Have nothing, not even essential words!
