Introducing Compass! • Check and lock your magnetic heading. • Measure surface levels with pitch and roll. • Save GPS location marks and export as CSV, GeoJSON or GPX. • Explore magnetometer, accelerometer and gyroscope readings. • View magnetic anomalies, FFT vibration peaks and the 3D gravity vector.
Compass, Level, GPS Marks, location logs & sensor diagnostics.
Explore useful navigation, measurement and sensor tools in one app. COMPASS • View your magnetic heading in degrees. • Lock your heading for easy reference. • Copy your heading or save it as a mark. • Sensor fusion and magnetic noise filtering help provide a steadier reading. 📐 LEVEL • Check whether a surface is level. • View pitch and roll angles in real time. • Check the alignment of shelves, tables and furniture. • Use the optional LED level indication. 📍 GPS MARKS • Save your current location as a waypoint. • View latitude, longitude and location accuracy. • Organise saved points using Default or Project. • Enable passive GPS logging when needed. • Export location data as CSV, GeoJSON or GPX. • Save and review location marks without route guidance. 📊 SENSOR DIAGNOSTICS • View magnetometer readings in microtesla (µT). • Monitor accelerometer values on the X, Y and Z axes. • View gyroscope readings in radians per second. • Explore magnetic anomaly visualisations. • Examine FFT vibration peaks and the 3D gravity vector. • If the compass heading gets stuck, move your phone in a figure-eight pattern. IMPORTANT INFORMATION • The compass displays magnetic heading, which may differ from true north. • Nearby magnetic objects and electronic devices can affect compass accuracy. • GPS accuracy depends on your device, satellite reception and surroundings. • Sensor features depend on your phone's hardware. • This app is not a utility locator, aviation navigation instrument or survey-grade measurement tool. • GPS logging is optional and can be switched on or off. Compass, Level, GPS Marks and Sensor Diagnostics — practical tools together in one app.
