I do not want to update to the new version but the #4 sends me to your web page and no longer works. I use a dictionary everyday and have had to go to the web for my dictionary needs. Please fix version 4. Today, the best dictionary reigns again. Thank you for the update, now, all is calm, all is bright.

An education in the English language. Great definitions, sometimes including useful pictures to illustrate the concept, and (as far as I’ve found) always having a button to give audio pronunciation of the word. Includes surprisingly useful background in how the dictionary is developed, history of the English language, and a comprehensive listing of Indo-European roots… that I didn’t realize would be useful to have til I’d been using this dictionary for a few years! NOTE - this version of the dictionary is MUCH better than the other one available as an app… I got confused and thought support for this version had been dropped and bought the other one… really a shadow of the value!

Not working on iPad Pro 11” (2020). When you open the app, you get a flash screen that says “total failure” before sending you to the App Store. Please fix.

I bought this dictionary in 2010 and used it almost daily until I updated it a few days ago. It now won’t let me into the app, popping me right back to the menu.

Back then this was the most expensive thing i bought on the iPhone , i think it was $30 and 9 or ten years ago was a lot of money . I remember it took me a long time to download because i was downloading it over 3g and it was a lot of MBs and 3g was slow back then . Thanks for keep updating this classic .

But every time I try to use it, it puts up a pop up box to get me to rate it five stars.
