Constantly bugs me to upgrade to the paid version. ads that get in the way of the words I'm looking up and that are often difficult to close. bugs such as not selecting the definition I'm tapping or ads refusing to close despite having the option. and then getting told to upgrade again. extra star for the fact that it is a dictionary with words and definitions. but come on, even the *pronunciations* are pay walled. be so for real.

This online dictionary has become my favorite. For those who have trouble spelling, especially of words not often seen in the 21st century, it's very useful. I use it in dark mode because it's easier on my eyes than other dark mode dictionary apps. I love being able to save my favorite words that I learn when I'm unfamiliar with terms that scholars utilize. That allows me to refresh my memory. I give this five stars.

I paid for a subscription because I genuinely like the Oxford Dictionary. Unfortunately this app sucks. A lot of words that I would regard as very basic do not come up when you search. Despite having the premium subscription there is no way to back up & transfer any of your saved favorites to another device. The "help" section for mobi systems is completely useless, and checking the forums anytime a user asks a question all they get is a canned response "we're discussing it with our team"
