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 love the Dictionary app. It helps me spell words properly and helps me get a deeper understanding of definitions so I can communicate more clearly. It's fun to learn new words and the history behind those words. My favorite is the thesaurus. There are so many ways to use different words that are of similar meaning, which can lead to even more learning and understanding. Great fun! Excellent app!

I deleted my 5 star review because it pertained to the old version. I downloaded the new version and haven't been able to use it since. All that shows on the screen are the improvements. Each improvement has a link, and at the top corner, there is an X to close the current screen. None of them work. Any link or the X can be pressed multiple times with no changes. Numerous presses make it easier to take out my frustration. If the developers figure out a fix, may try again.
