Description of Alt

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.

Reviews of Alt

  • 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).

    Thanks for the review! I’m glad you’re enjoying the app. In regards to your issue, please go to Settings->Alt-O-Meter and ensure that you’ve enabled the “Motion & Fitness” permission. The app needs that enabled in order to detect your ambient air pressure, otherwise it falls back on showing GPS altitude. No other motion or fitness data will be accessed by the app; only ambient air pressure. Thanks again for using my app, and I’m glad you’re enjoying it!

  • Awesome!

    I love this app! Also useful for baking as recipes need to be adapted for the altitude. Love it!
