Extremely accurate. I wanted to purchase the pay-for version but it doesn't keep a log of the barometric pressure, which is what I'm most interested in.
Useless! Waited 30 minutes multiple times on multiple locations on a clear sky on the mountain and this measured nothing. Other apps worked well though...
The location shown on the photograph is incorrect. No matter where i click the pic, it always shows one place. The elevation though is right.
Will not allow screen overlay even when I go to settings to allow it. The app does NOT work.
For up/down indoor stair climbers. Needs 1 second samples taken versus 1 Minute samples. Needs History graph horizontal in 01 feet or 05 feet increments versus current 50 feet.
Now you can pick elevation for any point directly from the map.
Added several maps layer.
