Very difficult and frustrating to simply look up a word without the focus going to something else, because the app is very sensitive to touches. As you move down to read a definition, it is very easily activated to go to something else (to another related word or an ad). There is not a way to go back to the word being looked up without starting over and re-entering it. The app is not very user friendly.

I purchased the ad-free version several years ago. I use the thesaurus daily. I love the app, and I love having unfettered access to a great dictionary & thesaurus. I only have 2 complaints about the app; first, when I open the app and put my cursor in the search bar, the keyboard disappears even if I am typing; and second, in 2024, the price went from $1.99/year to $5.99/year.

The app doesn't work as stated. I contacted support by email and their response was "noted'. no help, but a few links and nothing of value. It said before I downloaded it that word finder was part of the app. A simple question, but their support desk could not tell me either way. It is ok as a dictionary only. the layout is not functional and no search tool for parts of the app such as word finder. Not worth the money, maybe ok as free, but I made the mistake of paying for remove ads as 2 many
