The best dictionary app I have used to date

This is the best Dictionary, Thesaurus and vocabulary apps I have used to date. Have had a few minor crashing issues in the past but, nothing the last few months. This app is great I wish it could integrated into mail and some other apps. The word of the day is prodigious asset. For years I have had a extensive unabridged hard cover $600 dictionary on a pedestal in my sunroom I use to highlight a different word each day. With this app I now get two. Keep making improvements worth every cent of $10, you get all the information of an unabridged dictionary and copious amount of additional information. And before anyone makes a crass comment about highlighting a fine dictionary I use a special archival highlighter. It is meant to be used not collect dust. Just like this app. Use it to appreciate it.

It Works!

I love this app. Most of the words that I look up are found with no problem and the definitions are pretty accurate. I also get much use from the synonym feature. I was pleasantly surprised by the voice feature where I speak a word to do a search. It has about an 80% accuracy rate so it's not as useful as it could be but still I like this feature.

Nothing really more to add. The app continues to very useful, especially when I encounter new words. I continue to have a high regard for this app.

Fantastic Product

This Dictionary is the go to place to find any words. If you can not spell the word. Do your best and you will receive a list of words to choose from. If you still can not figure it out try putting in a word that means the same. Like a synonym, then you can look under that particular word list of synonyms. Wallah there is the word you had wanted to use. Great programs and they have a slew more programs besides just a dictionary. Try them all, wow Premium Dictionary & Thesaurus for iPad
