Random House K.W. College Dict

This is probably the best offline dictionary available for Android. The UI looks really nice and is intuitive. You get the very latest science and tech terms as well as both American and British pronunciations for most entries.

I spent good money for the dictionary. I have two HUGE problems with it: First, I have to start a VPN for it to confirm my license each and every time I want to use the program. That is stupid! It should have properly registered itself before I installed it, that I have already paid for it. Why does it need to confirm my license each and every time I use it? Second, the splash screen and loading time takes about four times more time than any of my other dictionaries. That is ridiculous! -------------------------------------- Update... Two months later, I still have not been able to use the dictionary once, now even with VPN. I hope DaolSoft, or the publisher of the dictionary, would see this issue and solve it ASAP. This is crazy! When I first got the dictionary, I needed it for a class, for it was the only dictionary that use IPA for American English. I liked that feature.
