Machmeter

Machmeter shows your current forward velocity as a factor of the speed of sound, or MACH.

Use in any vehicle or no vehicle at all-- impress your friends with detailed readouts showing just how much slower than the speed of sound you are actually traveling.

Machmeter is for entertainment purposes only. It should never be used in place of an accurate speed gauge under any circumstances.

To enter a ten-second demonstration of simulated speed, double-tap with three fingers.
