I've always had a strong fascination with words, especially the subtle shades of meaning that can be expressed when the right word for a special circumstance is chosen from among the tens of thousands available for use by English speakers and writers. Now in transition from a career in medical science to writing poetry, this app is a trusted friend assisting my frequent searches for just the 'right' word for my needs of the moment. It helps validate my lifelong aversion from the use of jargon to express exactly what I meant to convey for all those years. Clients in my past life also appreciated this stylistic skill as well. Thank you for not shying away from including subtlety and complexity in the construction of your app. I look forward to watching and benefitting from your ongoing efforts to evolve this service into an even more perfect tool for us to use.

Love this Dictionary, convenient App, can't live without. As a young girl growing up My Father never told me how to spell a word or what it meant. Instead he always made me get out the Webster's Dictionary and look it up. He made me learn how to look up a word by sounding it out even if it took me hours looking at almost every page. This helped a lot in school and my work years. Downside of course was you need to know how to spell the word to look up a word in the Dictionary and this was very frustrating as a young girl. My Father could never understand this logic (or could he) and used this as a teaching moment mainly Patience!! Now that I have been retired for a number of years I find I am using the Dictionary more. Could this be the meaning of "If you don't use it you lose it"??


I couldn't ask for anything more in a dictionary/thesaurus app. I'm completely satisfied and use it very frequently. To hear the word spoken, is especially helpful. I like it so much, I have purchased all upgrades. I find every single upgrade absolutely invaluable. Having the Greek word origin as well as the Latin word origin really helps me understand words in a way I haven't ever understood them before. All the individuals responsible for the development & continual updates of this family of apps deserves an enormous round of applause for a job extremely well done. I have yet to find a glitch or a typo – – and I'm a natural born typospotter. They drive me crazy. It is an absolute pleasure to enjoy learning from every single thing I use these apps for. Thank you! Dictionary & Thesaurus Premium
