TypeLingual is a language learning tool as an iPhone app that lets you see a foreign translation of what you type in real time. Its goal is to aid English-speakers who are learning a second language by building vocabulary.
TypeLingual functions as a custom iPhone keyboard, meaning that you can use it in any app in which you can type.
By repeatedly showing translated phrases consisting of words you actually use, TypeLingual helps you passively build your knowledge of a foreign language. Its primary advantage as a learning tool is allowing you to focus on words and phrases that you will frequently use in the real world.
Special thanks to developer Alexei Baboulevitch who created and open-sourced a generic keyboard. His work was a great help to this project.
