JTravel - Jewish Compass

JTravel is the most accurate compass to Jerusalem and zmanim calculator, designed for Jewish travelers. COMPASS TO JERUSALEM Find the exact direction of prayer from anywhere in the world. JTravel uses true GPS bearing calculations — not magnetic north approximations — and can be verified against celestial bodies (sun, moon, planets). PRECISE ZMANIM Halachic times calculated from your exact position, altitude, and true solar time. Supports both GRA and Magen Avraham calculation methods. Tap any zman to learn the halachic source and reasoning. WORKS IN AIRPLANE MODE Enter your departure and arrival airports, and JTravel interpolates your position along the great-circle route.
