Global Locator vs Trailseek

Your position in 19 coordinate formats, a GPS camera that stamps every shot, and tracks that lead you back — all worked out on your iPhone, signal or not. A precise coordinate reader, converter and navigation tool for hikers, geocachers, surveyors, photographers and travellers. EVERY FORMAT THAT MATTERS Decimal Degrees, DMS, DDM, UTM (latitude band or hemisphere), MGRS, USNG, UPS, GEOREF, Plus Codes, Maidenhead, Geohash and ECEF — plus the Greek (EGSA87), British, Irish, Dutch RD, Swiss LV95 and US State Plane grids wherever they apply, and optional Mapcode. Read older paper maps in ED50, NAD27 or OSGB36. Pan the map and every format updates together; copy any one with a tap. PASTE ANYTHING Auto Detect works out what you pasted — a grid reference, a map link, a geo: URI — and tells you what it found. Batch Convert handles a whole list or CSV at once. Scan a QR code to read a location, or show one to pass a point to another phone. MAPS THAT KEEP WORKING Maps standard, satellite and hybrid, plus OpenStreetMap and OpenTopoMap with contour lines. Areas you view stay available offline. Overlay the UTM/MGRS grid, favourites and tracks. NAVIGATE TO ANY POINT The compass says "Turn slightly right" with the distance, shows true or magnetic bearing, and waits for a good fix before saying you've arrived. Voice guidance works with the phone in your pocket; a Live Activity keeps the distance on the Lock Screen and Dynamic Island. AR navigation places a marker at the target's true bearing. TRACKS Record your route in the background, even when locked. See distance, moving time, speed, elevation gain and an elevation profile, then Retrace it back the way you came. Import and export GPX, KML and CSV. GPS CAMERA Photos and video stamped with coordinates, address, altitude, heading, time and a mini map, in four templates. RAW capture and Camera Control support, and the position saved in the photo's metadata. GPS Photos maps every shot and exports a PDF report, CSV, KML or KMZ. GEOCACHING Formula Solver for multi-caches, plus letter values, cross sums, ROT13 and Roman numerals. Corrected coordinates for solved puzzles, GPS averaging for hiding a cache, waypoint projection, distance and bearing, and a find log with notes. FAVOURITES AND FIELD LOGS Save places in coloured categories, with photos. Sort by name, date or distance, and get an alert when you come near one. Field Logs keep timestamped notes and photos at your position, exported as PDF, CSV, KML or KMZ. ALTIMETER AND GPS QUALITY GPS and barometric altitude side by side, air pressure and its trend, and QNH calibration. Speed, heading, course and magnetic declination. GPS Quality charts accuracy over time, recognises external receivers and predicts the satellite sky — GPS, GLONASS, Galileo, BeiDou, QZSS and NavIC — with DOP for the next 12 hours. WIDGETS, SIRI AND SHORTCUTS Home Screen, Lock Screen and StandBy widgets for coordinates, all formats, your target, altitude and pressure. Ask Siri where you are, save where you parked, navigate to a favourite, record a track or take a GPS photo. Open the camera from Control Center or the Action button. 25 LANGUAGES Fully translated, with right-to-left layout for Arabic and Hebrew and the compass rose in each language's own convention. Switch language inside the app. PRIVATE BY DESIGN No account, no ads, no analytics, no tracking — the developer collects nothing. Favourites and tracks can sync through your own iCloud, and Backup & Restore moves everything to a new iPhone in one file. Conversions, compass, altimeter, tracks and saved places all work offline. BUILT FOR THE FIELD Kilometres or miles, metres or feet. Light, Dark or System. GPS accuracy to suit your battery. 83 world cities built in. VoiceOver, Dynamic Type and Reduce Motion supported. Walking back to your car or reading a grid reference on a ridge — Global Locator gives you the number you need, in the format you need it.

Trailseek is an offline GPS app for hiking and backcountry travel. It records your track, marks waypoints, shows where you are on topographic and satellite maps, and points you back to any spot. Your location and data stay on your device. Maps - Free maps with no account: Apple Maps, satellite, hybrid, OpenStreetMap, OpenTopoMap, and USGS Topo. - A 3D terrain option adds relief to the Apple maps. - Download USGS Topo areas and use them with no signal. - Turn on a coordinate grid for latitude and longitude, UTM, or MGRS and USNG. Waypoints - Drop a waypoint at the map center, your location, or a long press. - Set a name, an icon, a color, and a note. - Attach photos from the camera or your library. - Search and sort the list. Tracks - Record distance, time, speed, and elevation. - Elevation comes from the barometer and GPS together. - Recording continues with the screen off. - Review a saved track's stats and elevation profile. Navigation - Follow a compass arrow to a waypoint, with distance, bearing, and ETA. - It uses GPS and the compass, so it works with no signal and no map. Coordinates - Show your position as decimal degrees, degrees decimal minutes, or degrees minutes seconds. - UTM and MGRS/USNG are always there. - Tap a value to copy it. GPX and sharing - Import and export waypoints and tracks as GPX. - Share a waypoint or track as a file, plain coordinates, or a maps link. Drawing - Draw on the map with Apple Pencil on iPad or a finger on iPhone. - Drawings stay fixed to the ground as you pan and zoom, and share between devices. iPad - The map fills the screen and the panels open as popovers. Apple Watch - Record a track, mark and browse waypoints, and navigate from your wrist. - See your track and waypoints on the watch map. - Waypoints and tracks sync with your iPhone. More - A ruler measures distance and bearing between two points. - Sunrise, sunset, moonrise, moonset, and the moon phase for your location. - A trip computer tracks distance, moving time, and average speed. Privacy - No account, no sign-in, no ads, and no tracking. - Your tracks, waypoints, photos, and location stay on your device. Trailseek does not collect them.
