Altitude Drive vs GPS Altimeter

See your altitude change in real time. Altitude Drive fuses GPS with your iPhone's barometric pressure sensor for a live elevation readout on iPhone and on CarPlay. WHAT IT SHOWS • Current altitude in feet or meters • Vertical rate of climb or descent (ft/min or m/min) • Road gradient as a percentage — the same definition highway grade signs use • Compass heading with cardinal labels • 5-minute altitude history graph WHY IT'S ACCURATE GPS altitude alone is noisy and slow. Altitude Drive pairs it with your iPhone's barometric pressure sensor for the small, fast changes — so a single step or a subtle road grade shows up immediately, while the GPS keeps the absolute reading honest. DESIGNED FOR THE ROAD — AND THE TRAIL On CarPlay, a clean dashboard view shows altitude, trend, gradient, and heading at a glance. Color tells you both direction (red, white, or green for descending, level, ascending) and severity (green through yellow to red as the rate intensifies) without taking your eyes off the road. On the phone, everything is large, monospaced, and readable in motion. Mount it on the dash, hand it to a passenger, or take it on a hike. TRIP COMPUTER Like a car's trip computer, Altitude Drive remembers the highest and lowest elevation you reach and your steepest climb and descent. Reset with a single tap for a new drive — your trip is kept even across app launches. PRIVATE BY DEFAULT No accounts. No ads. No analytics. No third-party SDKs. Your location data is processed entirely on your device and is never transmitted anywhere. REQUIREMENTS iPhone running iOS 17 or later. Location ("When In Use") and motion permissions, asked once on first launch.

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.
