Makkah

The compass points to the Kaaba [green ring] (shortest path using the WGS84 ellipsoid) and also indicates north [black ring].

Today and tomorrow's prayer and sunrise times are displayed for your current location automatically, no need to manually enter your whereabouts. A green alarm icon means it's set and white is unset.

The compass is only as good as your hardware allows, avoiding magnetic fields, placing on a flat surface, and recalibrating (such as waving your device in a figure of 8 motion) will improve the reading.
