The app name describes it perfectly. It simply uses GPS to find altitude and it doesn't require Wi-Fi or mobile signal to function. The app also gives latitude and longitude very precisely which is what GPS was designed for. Determining precise altitude from GPS is not quite as quick. However position yourself for as much unobstructed sky as you can and accuracy progressively improves. TEST: First altitude was 26 ft above actual. After 3 min altitude was exactly correct.

Does exactly what it says and as far as I can tell it's accurate to within a few metres vertically. Thank you to the Devs, this just works, no fuss, clear display, simple to use. :-)

??? Who has the most accurate elevation??? Ive tried 3 different apps and they all disagree on the altitude. From 20 meters to +100meters difference.
