Alt-O-Meter 4+

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).

Developer Response ,

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!

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.

Version 2.0 is now available with support for metric units. Enjoy!

Awesome!

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