Customer Reviews

Love it!!!

As I got older, I thought I would come to a time in my life that I would not need to use the dictionary anymore--because by now I would know all the words that I need to know in my readings and interpersonal communications, and could get by without the words that I don't know. WRONG!!!

It seems I need the dictionary more than ever, not only for when I see new words but also to help me recall definitions and the proper use of the ones I thought I already knew. I have learned there will always be new words to learn and understand. In this social media age, I grieve over the rapid demise of the English language. I am thankful for the Dictionary app and what it can do to counter this and revive the art of communication.


I highly recommend this product. On a scale of 1 - 5, I rate this app at a 5+! I use the basic version of DICTIONARY. It's EXCELLENT!
This app is very user friendly, especially for a "novice techie." I can easily scroll back to review previous words of the day. You can receive the word of the day alert. The app makes it so simple to access various aspects of the word that's being defined, e.g. it's definition, origin / etymology, synonyms, proper use in a sentence, etc. Additionally, I can bookmark any word. Likewise I'm able to send or copy a word.
Altogether the product is robust, uncomplicated & simple to use. My experience has been one of hassle free ease of use. Very satisfying. Because of my ongoing positive experience I plan on upgrading.


Look, all I want is to verify that I am using and spelling words correctly and, because I like playing with subtle differences between synonyms, I need a good thesaurus. This App is very good (not excellent) at providing those features. But the increasing amount of advertising, the shifty pop-ups, the badgering to "Upgrade," and the alleged enhacements significantly slow things down. Why would I want to watch a video when I am in the process of writing and merely wish to check a word or two? It's annoying to have the convenience and speed of an electronic at-your-fingers dictionary/thesarus undone by having to wade through ads and unhelpful announcements before getting to the information I want. If I timed it, I bet it usually takes the same amount of time that looking something up in a book takes. Dictionary & Thesaurus
