Greek English Dictionary is an offline and free mobile application from BAPPI that provides a comprehensive language learning tool for users. It allows users to search for both English and Greek words, directly from the internet browser or other applications by using the sharing option. The dictionary also functions as a learning tool, with features such as Multiple Choice Question (MCQ) option, autosuggestion, and speech-to-text.

One of the standout features of the Greek English Dictionary is its ability to function without an internet connection. This makes it an ideal tool for language learners who do not have access to the internet at all times. Additionally, the app has an option to turn off auto-search to type quickly, which is useful for low profile mobile handsets that may experience slow typing.

Other notable features of the Greek English Dictionary include antonyms and synonyms, backup and restore, history and study plan, word games, and the ability to share and copy words. The dictionary icon on the notification bar also makes it easy to start the app quickly. Overall, the Greek English Dictionary is a valuable tool for language learners and anyone looking for an offline dictionary on their Android device.
