GPSense — GPS Test & Status

GPSense shows everything your iPhone knows about its position, clearly, on one screen. Check the quality of your GPS fix before you rely on it on a hike, at sea or in the field. STATUS • Fix status (3D / 2D / no fix) with the reason when there is no fix • Horizontal accuracy and an estimated source: GNSS, Wi‑Fi or cell • Coordinates in decimal degrees, degrees‑minutes‑seconds, degrees‑decimal‑minutes, UTM and MGRS. Tap to copy, or share. • Altitude above sea level with ± accuracy, plus ellipsoidal altitude • Speed with session maximum, course with cardinal direction • GPS time in UTC, age of fix and update rate • Barometric pressure and vertical speed (on iPhones with a barometer) WORLD • Borders‑only world map with the live day/night terminator and the sun’s position • Your time zone highlighted, local and UTC clocks, today’s sunrise and sunset COMPASS • Rotating dial with true or magnetic north, heading accuracy and a calibration hint • Course arrow when you are moving, and a pointer to your saved waypoint TRACKS • Record tracks while GPSense is on screen: distance, moving time, average and max speed, ascent and descent • Export any track as GPX and open it in your favourite mapping app WAYPOINTS • Save your position or type coordinates, then see distance and bearing on Status and the compass PREDICTED SKY • Where GPS satellites should be above you, from the nominal constellation. Clearly labelled as predicted: iOS gives apps no live satellite data. WIDGETS • Home Screen and Lock Screen widgets with your last position, and a Live Activity while GPSense is open APPLE WATCH • Fix, accuracy, coordinates, speed, altitude and pressure on your wrist • Complications with the watch’s last position on your watch face SETTINGS • Metric, imperial or nautical units • Keep screen awake, light/dark appearance PRIVATE BY DESIGN No accounts, no ads, no analytics, no network access. Your location never leaves your devices.
