Altitude Drive vs Altimeter Dashboard

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.
