Great tool at my finger tips

I do love this app. Nice quick way to get definitions and synonyms with the thesaurus component. Plus it is able to be used by other apps that have a define option in them. Like with my smartphone if I highlight a word one of the options is define. Last but not least the word of the day is kind of cool. I like it but sometimes I don't really want to look into that is no big deal. And I really think that is the beauty of it it won't keep bugging

Really glad I got this app. Find it very helpful and convenient. The only reason I gave it four stars instead of five is because sometimes it defines words with the word. I am no scholar but I don't believe that is ever the correct way to define a word. With this said I still am a big fan of this app and would highly recommend it. One of my favorite features is the word of the day. I love to add to my vocabulary and it's a great and convenient way to do just that.

Dependable, makes ME look good !!

1)Most definitely worth the purchase. What helps them - helps you !
2)I use this almost every day. A GREAT source of reference. Thank you ! ! !
3)Voice search helps when I can't spell the word. Still a great app ! !
4)If they ever have a DEAL on the SCIENCE & MEDICAL add-ins ( like both for $2.99 or better) I'm in !! Since I know I'll nd some 'vocal add-ins' soon, I could really use a deal. How about you?
5)Tried a few others, but this one is STILL the BEST !!' Haven't missed yet and easy to understand. At least get the 'voice' option. Helps " nun-e-ate " words that are beyond my comprehension.
Still 5 stars, too !!!
6) I still rate this at the TOP of my app list. I use it at least twice a day, for a definition or to pronounce a word I haven't heard before. GET THIS APP - and support them w/ a purchase of an option.
5 MORE Stars !!! lol

A lifeline

I'm a civil engineer and a able to do higher level math, apply advanced science and develop solutions for complex problems. I can write, speak and explain the same to just about anyone with distinctly brevity.

What I cannot do is spell - even words I have written a few thousand times. My mind has never worked that way.

So, enough about me - we'll almost - my opinion/ rating of this app.

For someone like me - tapping the (far to small) microphone to initialize the voice recognition routine - then tapping the ready prompt - saying a word and having it pop up is wonderful!

It almost forces me to wonder why they don't include add in apps for PB&J, cold-cuts, or at least how to build a better sandwich! Dictionary & Thesaurus
