Fairly Good Dictionary App

I have been using this app for a few years, and I finally got sick of the “Review now, Ask Me Later” dialogue box enough to post a review:

It’s a good and reliable dictionary app. I have three total dictionaries on my iPhone, because no single app is enough; although I’ve had this one longest. It has the nice, desirable feature of speaking the word selected. It does a better job than most at providing an accurate pronunciation for most words, but the fault for those words not correctly pronounced is hard to place, as the device itself might often own the blame. I like the feature of inputting first few characters of word during search, which avoids lost time for searching out words that spelling is unknown. I mean, in all but a few cases, I search for spelling purpose more often than definitions. In cases I want definition, it provides good and detailed information, plus derivatives.

I like it, use it often and recommend it. I only give four stars because I have yet to see a dictionary app that is good enough to rate all five...But this one gets top spot.

My Go-to app!

As a child I was taught to "look it up". I learned that my parents were not always going to give me the answer or guess the answer. Later guessing wasn't satisfactory to me either, so I bought my very own dictionary and thesaurus on campus. This dictionary is even more than I expected and a joy to search, even medical terms are defined. At 69 and disabled I spend even more time reading and studying. Word origins are an interest of mine and are included in this app. Get it.

Excellent content, well presented

The lexicon is surprisingly complete for an app that isn't cloud-based. The writing is succinct and the presentation elegant but not flashy. My one criticism would be the search button, which is small and sequestered in the top bar despite the fact that you have to tap it to look up words, which is the whole purpose of the app. Consider the floating action button from Material Design.
