Speed is a drop-dead simple speedometer for Android that uses the location data from the GPS to provide a near-accurate representation of how fast you’re actually traveling. Featuring lush graphics and a clear, legible display, Speed is the perfect bicycle, boat or train speedometer. Both kilometers and miles per hour are supported, and a landscape mode for widescreen operation. Simply tap the dial to switch between miles, kilometers and knots.If you’re on Android 3.x or above, double-tap the dial to flip it upside down so you can reflect it off a surface (like a windshield) as a heads-up-display.NOTE: As this works using the GPS, you will have to be moving at a certain minimum speed for it to register, and from testing it seems to be 5km/h. Ergo walking won’t normally make the dial update unless you have super-accurate GPS coverage.Some phones have better GPS than others; if you’re having problems using Speed feel free to send us an email with your make of device and what ROM you’re using and we’ll see if we can help!
