CompassGuru

Find true direction and level any surface with CompassGuru — a fast, accurate compass and spirit level built entirely on your device's own motion sensors, with nothing sent anywhere. COMPASS Point your phone and see your heading update smoothly and precisely, fused from your device's gyroscope, accelerometer, and magnetometer for stable, low-lag readings — not a jumpy raw sensor feed. Cardinal directions are shown in both English and Chinese (North, East, South, West) for quick, clear reading at a glance. If nearby magnets or metal are distorting the reading, CompassGuru detects the interference and warns you, so you're never misled by a bad reading. SPIRIT LEVEL GUAGE Switch to the level screen to check whether a surface is flat or whether your device is held perfectly upright and plumb. A bubble shows your tilt in real time, turning green the moment you're level. Use "Set zero" to calibrate against a known-flat reference, so you can level relative to a surface you trust rather than just the device's factory sensors. BUILT FOR PRIVACY CompassGuru works completely offline. It has no internet permission at all — the app cannot send data anywhere even if it wanted to. There are no accounts, no analytics, no ads, and no tracking of any kind. Every sensor reading is processed on your device and discarded the moment you close the app. WHY COMPASSGURU Tilt-compensated, sensor-fused heading — accurate even when the phone isn't held flat Magnetic interference detection, so you know when to trust the reading Bilingual cardinal labels (English + Chinese) Spirit level with calibratable zero point Clean light and dark themes that follow your system setting No internet permission, no ads, no accounts, no tracking — ever Whether you're hiking, orienting a map, hanging a shelf, or just curious which way is north, CompassGuru gives you a precise reading without asking for anything in return.
