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.
What’s New
Version 2.1
Fixed a bug that caused the altimeter to display the incorrect altitude in a recent version of iOS
Ratings and Reviews
Nice clear display, and appears to work
If there were some explanatory notes, I would happily give this five stars ... but so far, it's a matter of blind faith.
The AutoCalibrate feature certainly does something; but I know not what that might be !
The meter responds appropriately to me carrying the iPad up & down stairs [which is impressive], but I will need to check it at some O.S. benchmarks before knowing how much confidence I can have in its readings.
Developer Response ,
Since this app determines altitude by measuring air pressure, the auto-calibrate feature uses a current weather service to determine your local atmospheric pressure. Otherwise you can tap the little window in the middle of the dial and set it manually.
Need’s metres
Love this app. But it would be useful to be able to switch it into metres.
Developer Response ,
Newest version now supports metric units. Enjoy!
Needs hPa
You need to be able to see/set pressure in hPa (which most of the world uses) as well as inHg (which is used in only a few countries).
Developer Response ,
Newest version now supports metric units. Enjoy!
