Look Up -Pop Up Dictionary Pro is an Android app developed by Sharma Gaurav. It is a full version program that falls under the Education & Reference category, specifically Books. The app is designed to help bibliophiles and bookworms who hate going to Google for every tough word they face. It is also suitable for ex-iOS users who miss the nifty look-up feature.

One of the most significant features of Look Up is its offline pop-up dictionary, which supports 7 languages, including English, Italian, Spanish, German, Portuguese, and French. The app also supports various plugins, such as Urban Dictionary, Google Define, Vocabulary.com, Wikipedia, and Cambridge. You can search for words in three ways, which include on copying a word (Android <9.0), on pressing the lookup button after selecting the word (Android 6.0 and above), and on selecting a word and sharing it with the Lookup app.
