Works!

I used this in the mountains and the city and it agreed closely with posted altitudes. It was a little bit slower than CURRENT ALTITUDE FREE (the one with the airplane logo) but has a simpler display, something I appreciate after seeing so many apps with worse graphics than GoDaddy! Other than that either of those two free apps are keepers.
