Petrolr - Track Driving Habits, Routes, and Fuel Economy With Your Phone for iOS

Keep track of your fuel efficiency, driving habits and routes with Petrolr. Use Petrolr to turn your car into a connected car! Petrolr doesn't need any extra hardware to work -- NO OBD REQUIRED. Just your phone. We've used millions of lines of telemetry to build a computer model of vehicle performance. Applying that model to the data from your phone's GPS and accelerometer sensors allows Petrolr to estimate your vehicle's fuel economy(MPG) and performance characteristics.Continued use of GPS running in the background can dramatically decrease battery life.
