I got an altimeter/GPS speedo app for my iPhone last week and got a chance to test it out in the Colorado Rockies. I compared the
GPS speedo to the car and it was basically right on. The altimeter was very close to the posted altitude at several places I stopped and exact to the foot at the Alpine Visitors Center at Rocky Mountain National Park at elevation 11,796 feet. The only thing that didn't seem to work was me - I got altitude sickness - headache and nausea when I was above 10K'. Lots of snow in the mountains still at about 11K' and above. I got to see a lot of damage from last fall's floods in the Boulder/Estes Park areas and beyond. It was very extensive and many roads are temporarily repaired or still closed. I also got to see some of the damage caused by the mountain pine beetle. Very large areas of pine forest have been devastated by this tiny insect.
Now I can see how fast my boat is. The app is called Altimeter and Speedometer ver 1.0.3 by Thibault Vilon. I think the price was $0.99.
