As many others have said, this last update ruined the app. Not only does it look atrocious, so many features are gone. And like others, I paid for no ads, and now they are all over. The app needed an update, but this was in the wrong direction. I used it mainly for the Thesaurus, and now instead of a compact view of words, color coated for relevancy, it is overly spaced out blocks and you have to scroll through ads to see lesser fitting words or click to a different screen to see antonyms.

I couldn't recall if "contentedly" was a proper English word or not, so I looked it up on this app. It found no results, but linked to the word "contently." I thought that meant the word is incorrect, until I clicked on the link and found it defined by the word "contentedly!" To use one word to define another, yet not even have that word in your dictionary?! Go download Webster or Cambridge instead!

I used to enjoy this app so much, particularly for the Word of the Day. I also love the option to save words. I even paid for the ad-free version. Unfortunately the new update, which makes all the extra features free, has reintroduced ads for everyone and they are too intrusive for my taste. I'd happily pay an annual fee to get rid of them, but instead I am switching to a different dictionary app. :(
