Journey efficiency

Ever been walking around a town, and wondered if there's a shorter way to get to where you're going?

Or wondered if you going down that side road and over the roundabout is shorter than the way you usually go?

Well, you can work it out with Google Maps.

Or you can install an Android app I wrote, make both journeys, and see which one's most efficient. (This doesn't take into account time, only distance.)

You can get the app here: http://files.calum.org/JourneyEfficiency.apk.
