Do you have a need for speed? Operation: Speed is a simple speedometer app for your Android mobile device that can help feed the speed demon within. It will show you how fast you are going from 0-100 mph, and you have the ability to store as well as share and compare speed on the Swarm leaderboards. The app is only meant for racetracks and private roads, and the lower the speeds the more accurate it is. It is only as accurate the frequency at which the GPS data is received, but it is great fun and a great starting point for leisure and entertainment use.
