You can install the web app version here, however, the app is also provided within an iBook here if you have trouble with it (remember to use an iPad in landscape orientation). If you chose to use the iBook widget version, please be aware it was not designed for use in the iBook and the sounds will be delayed. If you previously installed the draft web app, it may be best to uninstall it like any other app and install it again using this tutorial. The web app has offline caching enabled so it is possible that it may load out of date files.

The accompanying document can be found here which explains the app’s idea, research, features, and why the wireframe can’t include all the features.
