Developer Fredrick Plotts recently published a language repetition and shadowing app he built with Hype; I was fortunate to be able to help him a bit with a few of the features.
This app helps teach Japanese by using repetition of phrases. Users can adapt it to their learning style by setting whether to loop, repeat, number of times to repeat, and amount of delay between repeats.

The app allows Fredrick to easily update the audio files and text phrases and publish new lessons using the same app framework.
