## Alt-O-Meter 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.

## Alt-O-Meter Reviews in United States

### ***** "As close as you get to a flight-certified alitimeter without actually being one"
Update: The dev's very responsive reply fixed the issues and my Alt-O-Meter is back to "it just works"! Thank you, dev, for the quick reply!  5* and well deserved.

Kollsman window & QNH missing. QNH no longer settable or reported. Auto Calibrate button now called "Start Updates"; when active, nothing much happens but the 100' pointer hunts erratically by a few feet. iPhone 12pro/iOS 17.4.1/app v.2.1 Those issues aside, this app holds truest to an aviation altiimter of all the others Restoring the auto-calibrate feature a while back was a big plus. Hoping the current glitches are only temporary... 5-star app! (-1 for the current issues).

### ***** "Awesome!"
I love this app! Also useful for baking as recipes need to be adapted for the altitude. Love it!
-- riellyst1, 2021-08-06

### ****- "Simple and clean design"
Nice clean design and does almost exactly what I need except doesn’t support the rest of the world’s standard units. Any chance you could add mbar’s/hPa for the QNH setting, and meters for altitude? They do need to be separate settings as some countries like Australia use hPa for pressure but feet for aviation altitude.
-- Catana48, 2018-08-25

### ***-- "Not bad but..."
Siri says I'm at 771' and your app says I'm at 739' (auto-calibrated). 

One of you is off by 32' which could get someone killed.
