Principium is the study aid specifically for Wheelock’s Latin, 7th Edition, available for iPhone. The app follows the text chapter by chapter, helping you to practice the grammatical forms for the model words, as well as all of the vocabulary. Macrons are optional, and macron entry is extremely simple: just enter a capital letter. Principium also has a handy glossary of the entire Wheelock’s vocabulary.
