Wordd is an iOS application developed by Andy Feng, available for free, under the category of Education & Reference. This app aims to enhance users' vocabulary through AI technology. Users can effortlessly search for definitions of words, acronyms, abbreviations, and slang. Wordd provides both official definitions and user-generated entries from Urban Dictionary, catering to a wide range of language needs.

One of the standout features of Wordd is the ability to have words read out loud by a robotic voice upon tapping them. Additionally, users can discover random words by shaking their device or using the random icon. The app also offers automatic suggestions for similarly spelled words and provides synonyms after defining a word.
