The device can be activated by making the sign of the cross, at which point it will connect to a companion mobile app. Wearers then have the option of praying the standard rosary, a contemplative rosary, or a thematic rosary that will be updated periodically. The system will track their progress in each prayer and monitor the number of rosaries completed.
The accompanying app can also deliver personalized religious content and the bracelet includes a health tracking feature. The eRosary is part of the Pope’s Worldwide Prayer Network and is intended to help users learn “how to pray the rosary for peace in the world.”
