There are at least a dozen compass apps for Android cell phones, plus
some that seemingly incorporate GPS, too. My Android phone happens to
have GPS. I use the phone a lot, running any number of apps, and i
usually get two full days out of it before the battery runs down to 20%.

You're on your own for the straight edge and protractor.

My son has an Android and he turned the compass app on. I held it
near a steel object and I was amazed that it deflected as a magnetic
compass would. The built in compass is NOT GPS based but seems to have
a solid state flux gate sensor that responds to the earths mag field.
I am very impressed by the Android.
