Empowering Muslims Worldwide with Precise & Private Qibla Direction.
Learn about Online Qibla Finder: our mission, client-side spherical geodesy algorithms, AR camera technology, and commitment to 100% private, zero-tracking Qibla direction.
Instant, universal access to the Qibla without mandatory app downloads or privacy-invasive tracking.
For over 1.9 billion Muslims worldwide, orienting toward the Holy Kaaba in Mecca (Al-Masjid al-Haram) is an essential precondition (Shart) for the validity of the five daily prayers. Yet, modern believers frequently encounter mobile applications that require invasive permissions, track continuous background GPS coordinates, mandate user registrations, or bombard worshipers with intrusive advertisements during sacred moments.
Online Qibla Finder was established by independent software engineers and Islamic astronomy enthusiasts to eliminate these barriers. We created a modern, zero-install web application that instantly converts any smartphone, tablet, or desktop browser into a laboratory-grade directional compass, interactive geodesic satellite map, and real-time augmented reality (AR) scanner.
By harnessing client-side HTML5 DeviceOrientation and Geolocation APIs, our algorithms run entirely inside the volatile memory of your browser. Not a single coordinate, orientation angle, or camera frame is ever transmitted to remote servers, logged in databases, or monetized for commercial advertising.
21.4225° N39.8262° EDesigned for Mathematical Integrity & User Sovereignty
Four foundational architectural commitments guide every algorithm, interface component, and update we build.
100% Client-Side Privacy
All calculations occur strictly within your browser's local RAM. Your exact geographic coordinates and camera feed never leave your physical device.
High-Precision Geodesy
Employs Great-Circle spherical trigonometry on the WGS-84 Earth ellipsoid to compute azimuth angles accurate to within fractional arcseconds.
Multi-Mode Versatility
Seamlessly transition between a 360° sensor compass, an interactive satellite geodesic line, an augmented reality camera, and a solar shadow alignment tool.
Universal Accessibility
Fully localized in 14 major world languages with full RTL support, optimized for high performance even on low-bandwidth networks.
How Online Qibla Finder Computes True Bearing
Direction to Mecca is defined as the forward azimuth along the shortest great-circle arc connecting the observer's coordinates to the Kaaba.
Spherical Trigonometry
Evaluates the inverse geodetic problem using initial latitude/longitude and Mecca's anchor points via forward spherical cotangent equations.
MEMS Sensor Fusion
Merges raw magnetometer triaxial readings with device accelerometer gravity vectors to continuously compensate for device tilt and tilt angle.
Solar Shadow Method
Provides an astronomical baseline for devices without hardware magnetometers, calculating the exact minute vertical shadows point toward Mecca.
📐The Great Circle vs. Mercator Projection Fallacy
A common misconception among travelers is using flat Mercator maps to determine direction. On flat cylindrical projections, a straight line represents a Rhumb Line (constant compass heading), which significantly distorts the shortest path across the curved surface of Earth. For instance, in North America, a straight line on a flat map suggests facing Southeast toward Mecca, whereas the true shortest geodetic path (Great Circle) actually begins toward the Northeast.
Our engine executes forward Great Circle formulas on the WGS-84 reference ellipsoid: tan(q) = sin(Δλ) / [ cos(φ₁) · tan(φ₂) - sin(φ₁) · cos(Δλ) ], ensuring that you face the shortest physical trajectory to the Kaaba across Earth's sphere.
🧭Hardware Calibration & Magnetic Declination
Smartphones use micro-electro-mechanical system (MEMS) magnetometers to measure the geomagnetic field. These sensors are susceptible to magnetic hysteresis and local magnetic fields from steel building rebar, laptop batteries, and magnetic phone cases. By executing a figure-8 motion, the operating system continuously estimates hard-iron and soft-iron distortion offsets.
Furthermore, magnetic compasses point to Earth's Magnetic North Pole, which continuously drifts. Our software integrates the World Magnetic Model (WMM) to calculate magnetic declination and automatically correct the needle to True Geodetic North.
Built by Independent Engineers & Astronomy Enthusiasts
All directional calculations, sensor fusion pipelines, and astronomical models are transparently engineered, peer-reviewed, and verifiable.
