Cant calibrate barometer without paying Barometer readings not available in hectopascals. USGS wildly innaccurate. SRTM came within cooee ± 5m at known height. This is no better than using a barometer app that can be calibrated and needs the internet. Pointless.
It's great! I used it to compare elevations hiking. My wife got altitude sickness at about 7,000 ft above sea level, so she chose not to go higher. That's good to know. My total climb was 2,000 ft! This app allows me to brag that in one day I climbed a height more than any building in the country.
ADs all over the screen When app is doing more work on CPU time to piss me off with damned Ad's then app is useless piece of crap.
Great app I am a pilot and this altimeter is as close as you can get to the real thing. Love it. Works great.
Oh My, How High Am I? It tells me.
Enjoying it I play on the water and am involved in hang gliding and hiking quite a bit. Comes in handy often.
