Turn your Android phone into a speedometer with SpeedView
Turn your Android phone into a speedometer to track current speed, average speed, and get 0-60 mph time and quarter-mile time.
Tracking your car's trip data can be fun and interesting, but not all cars come with an advanced trip computer. Using your Android phone's GPS sensor, SpeedView can act as a speedometer with some additional data functions.
The main screen of SpeedView displays a linear compass at the top, an analog speedometer, trip information and a speed graph. You can tap on the analog speedometer to switch to the numeric speedometer, while tapping on the trip data allows you to choose which information you want to display. You can choose between time, average speed, maximum speed, elevation, and clock.
Tapping on the linear compass will activate compass-mode, which displays a larger graphical compass.
To access more detailed trip information, tap on the speed graph. You'll find total distance, moving time, stopped time, total time, moving average, and overall average. This is where you'll also find the car acceleration option, if you want to get 0-60 mph and quarter-mile times while driving on a closed track.
Another cool feature of SpeedView is the HUD (head-up display) mode, which you can access in the settings, under the User Interface section. Check out a video demo of HUD mode below.
That's it. SpeedView is free, but also comes in an ad-free version (SpeedView Pro) for $2.95.
