RoadLabPro

Road Lab Pro is designed as a data collection tool for engineer by the World Bank in collaboration with Beldor Center, SoftTeco and Progress Analytics LLC. (http://progressana.com).
With accelerometers on your smartphones, this app evaluates road conditions, map road networks, detects major road bumps, and reports road safety hazards.
You can even upload a picture of potholes, black spots, or road accidents, etc with a simple tag. No data plan is required for running this app. All data collected can be emailed to yourself or uploaded to your own Dropbox account when wifi is available. To use the app, the mobile device has to be placed on a stable surface in your vehicle, preferably mounted vertically and tightly to the vehicle windshield.

Continued use of GPS running in the background can dramatically decrease battery life.
