The wrist-mounted device to assist pilgrims is an electronic device worn on the wrist that provides functions to assist a pilgrim, particularly a pilgrim on a pilgrimage to a holy site. The device includes a heart rate monitor that alerts the user when his or her heart rate is too high, a GPS unit showing the location of holy sites of interest, a monitor for keeping a count of the number of perambulations around a holy site, e.g., when performing a Tawaf, an audio playback device that will play back a prayer or scripture, such as the Dua'a, and an annunciator for announcing prayer times.
