I recently was made aware of a fantastic App called iChant for both Android and iPhone:

If you know nothing about chant and want to learn, this is a great app to help you get started. If you live in the Los Angeles area, just download it and come to the next KYRIALE CHANT ALONG at Mary Star of the Sea. I’ll show you how simple learning Gregorian Chant can be…
