Very useful

This altimeter app works great. We have used it for hiking, for driving around in the boonies, and for navigating city streets.

It works well even when cellphone coverage is spotty. We used it once to get to our car from a slot canyon, saving us miles in the heat. It performed almost as well as our $150 GPS.

Those who complain about the beeping? Dont they know how to turn the sound/ringer off? Silly people!

This is a great app for the price!
