Customer Reviews

The Wonderfulness of an app that

exceeds your expectations is always something to talk about, if you are a regular user of additional apps, no matter what type of instrument you are on. No, of course I do not love ANY app that requires purchases, to upgrade to the full benefits of its capabilities.
I DO like that everything it does, it does so quickly, without delay, quickly + flawlessly delivering on its further promises.
For those reasons, this is one of my favorite apps!
I frequently look up synonyms and antonyms when I am seeking more accurate and eloquent words - for ALL of our common, daily virtual interactions.

It is very helpful to me to know exactly the meaning of the words searching for as it helps me with solving cross word puzzles and for checking the rhymes for the words for writing poetry . Also it is helping me in finding the correct writing of the words that I misspelling . Thanks I like too much your dictionaries as it saves me time checking in dictionary books . Also it is a 5 stars dictionary summing all dictionaries all on line and quickly look the words in merely no time . This is a very good idea on line . Wishing you the latest updates all the time .

Convenient, Helpful

I love it. It's so nice to have a dictionary at ur fingertips. If I had to run to find a BOOK to look up a word for its meaning, I wouldn't be so apt to do it. But this way, I find myself searching for new words frequently, like something I hear on TV, for example.
It's pretty simple & straight forward, and it seams like any time they start messing with an app (trying to make it better, I guess) it just gets "buggy" and less user friendly. ITS A DICTIONARY, for heaven's sake! And it serves it's purpose well, just as is. Dictionary & Thesaurus
