4 Reasons to own WordBook

4 Compelling Reasons to own WordBook:

1) It contains a massive vault of excellent, superfluous and highly understandable definitions with an exhaustive Thesaurus that will enhance & expand your vocabulary.

2) You can add notes to any word (including your favorites) in the dictionary. This is helpful when you are adding notes to your 'favorites'.

3) It enables you to utilize iCloud sync to synchronize your favorite words & notes across all your Apple devices.

4)Excellent, clear audio quality for word pronounciations

The list above contains my personal favorite features of the dictionary app; however, there are so many other features in this app. If you are a big reader and/or writer, these features will benefit you greatly while you are reading/writing at your desk or while "on the go".

The only missing feature i could suggest is to show the "next" and "previous" word(s) listed in the dictionary as you are viewing your current word. Also, It would be nice to see all the words of the dictionary laid out in columns and the user can flip through the pages of columns containing words and be able to access each word and it's definition by just touching the word (via hyperlink).

I highly recommend this app for all readers, writers and public speakers. It will help you understand other people's writings better and help you be a better communicator.

Great quality for a low price!

WordBook is based on WordNet database from Princeton University. The content is concise and easy to read. This app does a good job in choosing text color and style, far better than other WordNet based dictionaries available in this store. It also provides brief word history information at the end of definitions.

Like many WordNet implementations, the dictionary provide semantic relations of words (they call it Links). This is unique and not available in any other branded dictionary like AHD, M-W or Oxford .

Pronunciation guide is in IPA (International Phonetic Alphabet), not popular in the US. Audio pronunciation is provided offline (text to speech) and online (2 voice options, one of them is the human voice). This is a great design. I appreciate not having to carry big sound files when I have only 8G in the iPhone.

WordBook shines when it comes to user interface. Everything makes sense and is at the right place.
Web access is genius. For every word, I can view the favorite online Urban dictionary in one tap.


This dictionary is well worth the price tag. The definitions aren't super extensive in my opinion, but I have been able to find virtually every word I've looked up so far. So it's great if you want to find out what that word means, but not always the best if you want to get specific about how to use a word, or which word you can use among synonyms (do braggart, boaster, bragger, and vaunter really all mean *exactly* the same thing?). The etymology is a HUGE plus, too, as are the web links for when you feel the need to go off road! Plus it is quite stable and straightforward.
