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!
Thanks!! I have been drooling over buying a Sheraton banjo barometer but the price!! Now I can check for storms as long as my battery is charged, even if I can't get to a website that has the hPa for my location. Took minutes to calibrate and it would have gone quicker except that I had to look around the web to find out what the abbreviations mean. So now I have digits in addition to hearing the blue jays scream or the woodpeckers drum or chatter, both of which are also signs of a storm on the way.
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.
Well designed but incorrect conversion Easy to read and well designed. I've used it for pitot-static calibration. The inHg reading however is off by about 0.03 inHg, which may sound small but is actually about 30ft of altitude. Probably too much rounding of the conversion factor.
