Customer Reviews

Great breadth

Your dictionary has both great breadth and depth. It includes words other dictionaries (nameless because they, too, are trying) do not list. Some of these words might be considered too new, or too casual, for others to list. Nonetheless, in my view, and apparently in yours, they deserve a legitimate place in the lexicon, for many persons, places, and qualities are not quite the thing and are most accurately described, not by drawing-room palaver, but by backstairs phrases that border on the louche.
As for depth, your dictionary offers more examples of usage, and, for that matter, near usage, (without additional cost) than any of the other dictionaries I routinely use.
Finally, your quizzes and historical tidbits are great fun, especially on rainy holidays as well as, occasionally, on those times when I should be hard at work attending to business.

Must have for writers, bloggers, and even teachers

The app is very easy to use and I have not been able to find a word it didn't have a definition, synonym, and antonym for. Uses words in easy to understand sentences so anyone can learn the word and how/when to use it.
There's also a tab at the bottom where you can switch to in order to find similar words. Some of which you will know and maybe even use every day.

It's just a great app to have for IPhone users (available for all smartphones). I use it several times a week and all day sometimes when writing.
Please download this app. You'll never have someone use a word you don't know again.

Dictionary! The Flawless Five-Star App e

Dictionary! Pro is one of the very few Apps that I am unable to find any flaws in.
I believe I spend more time using Dictionary! Pro than any other of hundreds of Apps on my iPhone.
They have made learning world history and our language fun and educational. Keeping score of your of progress is challenging. The scores from people all over the world; all over the USA; all over your state and your city. You can choose from many other ways to compare yourself.
I speak more professionaly every day and I'm having a great time.
Give it a try!
