GPSense — GPS Test & Status

Navigation

$0.99

See exactly what your iPhone knows about its position: fix status, accuracy, altitude, speed, heading, and your coordinates in five formats. 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.

  • This app hasn’t received enough ratings or reviews to display an overview.

Tracks keep recording with the phone locked or another app open, and show an elevation profile. • Pause, resume or stop a recording from the Lock Screen and Dynamic Island. • A larger Home Screen widget with accuracy, altitude, speed and the age of the reading, plus a record button. • A Lock Screen widget and watch complication that show the value you choose: coordinates, altitude, speed, accuracy or distance to your waypoint. • Siri and Shortcuts: ask for your position, save a waypoint, or start and stop a recording, also from the Action button. • Tap any value on Status to see it full screen in huge digits, handy on a bike mount or dashboard. • Coordinate converter: paste a position in DD, DMS, DDM, UTM or MGRS and get all five. • Barometric altitude you can calibrate to a known elevation or the local sea-level pressure. • Apple Watch: record tracks on the wrist, a waypoint complication, settings on the watch, and a watch app that works without the iPhone.
