too many ads. ** edit to reply devs:** I understand there is a way to remove ads. However, I like to try the product out first to see if I want to buy the full version, but because of the amount of ads I am unwilling to try it for long enough to want to buy premium. :) Previous subscription apps I've purchased in the past had fewer ad interuptions "for free", ensuring I had a pleasant experience to want to pay for premium. I hope that helps explain!

The app unexpectedly stopped working in the offline mode (I had been using it in this mode for a couple of years) and suggested that I download some huge amount of data. It took a lot of time and couldn't be comlleted anyway. I tried to reinstall the app and it demanded access to my personal data including photo and video. Good bye, "Oxford Dictionary of English"

Sorry to hear you are unsatisfied. We have a newer, a tad larger and considerably better Offline and Audio database. Please note that the app needs certain access - i.e. internal storage in order to save your favorites or access to you camera to translate captured words. Contact us at support@mobisystems.com and we'll assist further.

My favourite dictionary app so far. As a language student, it's very useful for me with the words' multiple meanings and examples. Though, it would be even better if it was 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 its hard for me to find the words one by one, so this app is a lot easier and more useful, i would recommend. 👏
