Using RoadBump is as simple as 1, 2, 3, 4. When you launch RoadBump, the "Waiting for GPS"  text is displayed until an accurate enough GPS signal is found. As soon a good signal is found, the text changes to being "Start".

When you press "Start", the text changes to "Stop". Drive the path you want to record and then press the "Stop" button.

When you press "Stop", you have made a recording. Now you can choose what you do next.
