Alt vs Altimeter Elevation Watch

Alt-O-Meter uses the barometer (air pressure sensor) in your late-model iPhone or iPad to calculate your precise height above sea level. Great for hiking, skiing, driving through mountain passes, flying, and more! • Reads ambient air pressure for a more precise reading than GPS. • Realistic, retro style. Looks like a classic airplane's altimeter! • Automatically calibrates for local atmospheric pressure. • ...also allows precise user calibration (optional; for advanced users) • Uses GPS hardware in devices that lack a barometer. • Completely free! No ads or in-app purchases.

Check your current altitude and see how much you have climbed. Altimeter shows your altitude, daily peak and elevation gain on hikes, bike rides and mountain drives. Use it on iPhone and Apple Watch, or view your altitude in CarPlay. ALTITUDE IN YOUR CAR The native CarPlay app has its own view for altitude, climb or descent per minute, grade, direction, peak and gain. It is an altitude display, not a navigation app. Set it up before driving. ALTITUDE WITHOUT SWITCHING APPS Start a Live Activity on iPhone to see altitude, peak and gain on the Lock Screen. Compatible iPhones also show these values in the Dynamic Island. Live Activity and the native CarPlay app are separate features. Widgets and Watch complications show your latest available altitude data. LOOK BACK AT YOUR ROUTE Record a track and open it on the map later. The line is colored by elevation; the color scale shows lower and higher sections. Daily history shows your altitude profile, peak and ascent. Monthly and yearly views help you compare your altitude history. FIT IT TO YOUR DAY • Display altitude in meters or feet • Check altitude on Apple Watch • Use Siri or Shortcuts to start a Live Activity or ask for your altitude • Optionally use existing Flights Climbed data from Apple Health in your analysis BEFORE YOU START Readings depend on GPS reception, sensors and location permissions. Background features require appropriate permissions. iOS and watchOS limit widget and complication refreshes; these are not continuously live displays. The app does not replace professional measurement equipment, navigation or safety equipment. ACCESS New users can try the app for two days. Continued access then requires a monthly subscription, annual subscription or one-time lifetime purchase. Existing purchases can be restored in the app. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
