Well, I guess we have our answer...
Thank you for contacting support for the mobile app. We appreciate you reaching out to us and congratulations on your child's acceptance to the United States Navel Academy! Unfortunately, the audio file for the Chant feature is not downloadable due to copyrights, and is setup just to play inside the USNA App. I am glad you enjoy this version, and we wish your child all the best at the USNA. Please let me know if there is anything else I can help with.
