HeightMeter displays your current altitude.
It also displays the altitude at which you started your trip, and allows you to enter a goal altitude.

Once you enter a goal, HeightMeter shows you how many meters are remaining until you reach your goal, and estimates your arrival time based on your speed.
The app uses high-contrast white-on-black fonts so that you can read the data even in sunlight.

Whether you're an alpinist, climber, mountain biker, skier, or just in general interested in your altitude: this app is for you.


Testing

I tested the application in the Austrian alps. The data was compared to a good, old, analogue Swizz altimeter.
The results: Obviously, the altitude data displayed in this app is only as good as the data received by the GPS receiver. For good altitude precision, the GPS receiver needs signals from satellites that are close to the horizon.
That means - in general - the better your view, the better the altitude data.
In my tests, the accuracy was +/-50m in valleys, whereas closer to the top of the mountain, there was virtually no difference between HeightMeter and the altimeter.
