This site and app were produced by believers. It offers some 27 different English versions, including the “Working Translation: A Journey Through the Acts and Epistles”, versions in a number of different languages, and several Greek and Hebrew texts. There are versions for iOS, Android and your desktop. By clicking on a word in the New Testament, you can pull up definitions from the Bullinger lexicon and Thayer’s lexicon. If you establish a free account, you can also take notes and save them in the app.
