Entertaining app.
The meters work perfectly and are customisable. Graphics are smooth, clean, and easy to read at a glance. This program does NOT have the option to turn off GPS to help save battery life. This program does NOT utilize the built in compass on the iPhone 3gs and is not nearly as good as it would be if it did. Both of these would be easy to implement into an update. Otherwise I love the app.
