Think about how much time you spend reading on your smartphone. Even if you are a bookworm, chances are you will come across a word you don’t know. That’s where you will need the Define app which is available on both Andriod and iOS. It is simple and provides an easy method to create a vocabulary list from an existing dictionary base that is not dependent on Wi-Fi unless you want to use Wikipedia, Wiktionary or do a web search of the word. Define provides a search tool to look up a word for the definition. The word is entered into the beginning page of the app in a listing by date, creating a simple vocabulary list of words and definitions at your finger tips in this app. A speak tool is available to read only the word searched, not the definition. If you have Speak Selection turned on in the Accessibility options, it will be announced aloud. For more definitions, selecting the Definitions tool provides you other uses and definitions of the word. A camera in the right upper corner allows you to take a picture or select a photo from your photos app. If you brought in a picture or image a Media category is listed where the pictures or web clips related to the word are able to be reviewed.
