Customer Reviews

Excellent resource & the ready

I love this app! Extraordinary to have accurate definitions always handy, as well as the very cool pronunciation tool for audible confirmation of the correct verbalization of the word. My kids make fun of me for my enthusiasm for the 'word of the day' feature but I know they have actually shared it on more than one occasion - if you have a happy baby boomer and a millennial with the same mobile app you got yourself a "winner winner chicken dinner" going on!!! Best value in the App Store bar none.

Glad this dictionary is in my toolbox

I didn't purchase other dictionaries before this one so I can't compare. I've had it over the years and it has everything I need.

Just purchase it and the extras. You'll never delete it or wish you never bought it. Use it diligently and be proud your command of the English language went from perhaps 1,000 to 3,000 words in your head after ten years.

What's not to like?

Highly Recommended App!!

This app is my go to reference for all my word related inquiries. I am in the medical field and this app does not miss a beat for medical dictionary inquiries. I recommend that you download some of the optional databases pertinent to your interest, application or occupation to customize your individual needs. I have used this app for at least 10 years and feel no need to look for an alternative word app. Keep up the good work! Great app!! Dictionary & Thesaurus Premium
