GPS Altimeter — a GPS elevation meter and barometer built for hiking, trail running, cycling, skiing and travel. See live altitude, pressure, coordinates, compass, speed and total ascent the moment you open the app. Clear numbers, simple controls, ready for the trail. 【Key features】 • Live elevation: GPS + barometer fusion, elevation chart, session max and ascent stats • Nearby landmarks: match cities and peaks worldwide so you can compare altitude on the go • Calibration: set a known elevation or QNH sea-level pressure before you climb for steadier readings • Track recording: save elevation profile, distance, duration and map path — with optional background tracking • Watermark camera: stamp altitude, place name, GPS and date on summit photos for easy check-ins • History: keep points and tracks on device; export CSV to review every outing • Units: switch meters / feet to match your preference 【Who it’s for】 Hikers, backpackers, trail runners, ski tourers, cyclists and travelers who want reliable altitude and memorable summit photos. 【Accuracy notes】 GPS elevation varies with satellites, terrain and weather — open sky is usually better. The barometer is excellent for relative ascent; weather changes can shift absolute values, so calibrate when you can. Indoors, tunnels and dense forest may drift. App data is for reference only — use proper maps and gear outdoors, and never stare at your phone on hazardous terrain. 【Privacy】 Core samples and tracks stay on your device by default. Location, camera, photos and tracking permissions are under your control in system Settings. Download GPS Altimeter and make every climb clearer — and easier to remember.

Verdict
The clearest difference is in-app purchases: GPS Altimeter at none against Watch Speedometer Pro CarPlay's 2. GPS Altimeter also leads on update cadence (weekly vs monthly) and iOS requirement (15.0 vs 26.0). Watch Speedometer Pro CarPlay's advantage is ads (none vs shown). On price and device support there is nothing between them.
