Sky Salah provides accurate Islamic prayer times for pilots at altitude. Unlike ground-based prayer apps, Sky Salah accounts for the horizon dip at flight level — at FL390, the horizon is depressed by 3.49°, shifting sunrise earlier and sunset later. The kinematic intercept engine projects your flight path forward and calculates exactly where and when each prayer event occurs along your track. Features: • Kinematic prayer intercepts — prayer times calculated along your moving flight path • Altitude-corrected calculations — horizon dip at cruise flight levels • Qibla direction relative to aircraft nose — in clock position format • Tactical Map with altitude-adjusted solar terminator lines • 6 calculation methods (MWL, ISNA, Egyptian, Umm al-Qura, Karachi, MUIS Singapore) • Mission Log — save and review waypoint prayer times • Traveler's Adhkar — supplications and prayer shortening guidance • 500+ airports with ground-level prayer times • Hijri calendar with Islamic event recognition • 100% offline — no GPS, no network, no data collection Built by a Muslim pilot, for Muslim pilots.
