Altitude Drive 앱 분석 (10월 4일)

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. PRIVATE BY DEFAULT No accounts. No ads. No analytics.
