## Description

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.
