Okay for free Not bad once you figure out how to make the initial adjustments to calibrate. The altitude reading is difficult to see down in the hundreds of feet. The adjustment for initial calibration of the barometer is very sensitive and you have to have a little patience. Once calibrated, it has been right on for accuracy. I live less than a mile from the nearest NWS/NOAA weather reporting station at the airport. The reading has been exact to the official readings. There is no set point indicator.
Amazingly accurate Took me a few minutes to find a few good spots to calibrate the altitude/pressure with, but once it was calibrated, seems absolutely accurate. Returning to spots I know the altitude of, it reads perfect, even adjusting a couple of feet as I hold the phone higher or lower. Did not expect this out of my phone sensor!
Confusing Just installed this on new phone. I'm on 14th floor but the altitude is saying -47 metres and the pressure is 14.77psi? How would I know my correct altitude and air pressure? I'm currently in a foreign country and this app could be much more user friendly.
Still testing Can't calibrate my altitude. The app only allows a couple hundred feet adjustment. So far, altitude is useless.
You are reporting hectopascals to zero decimal places. (While you do have inches of mercury to hundredeths.) That will not do. Should also be able to type in my altitude instead of adjusting the oversensitive slider.
Nice clean app, the plural of "feet" is "feet" I know English is super weird, but the plural is the same as the singular form of the word "feet" and I think you should leave it, but if you do make an update maybe change that one thing. But still a cool app!
