BMW M Power Meter App for iPhone

Car enthusiasts with iPhone’s should be happy to know BMW just released a free app that measures acceleration runs and g-forces on any car. Using integrated movement sensors, the App captures:

-Speed (mph / km/h)
-Forward acceleration (Forward g)
-Lateral acceleration (Lateral g)
-Travel time for a specified distance (e.g. 1/16-, 1/8-, 1/4-, 1/2- and full-mile runs)
- Acceleration to a specific speed (e.g. 0-30, 0-50, 0-60 and 0-100 mph times)

Sounds pretty cool, but how and how well does the handy little download really work? From MotorTrend:

“The iPhone must be laid flat pointing in the direction of travel or sitting upright at 90-degrees in order to get a measurement, so you might need a passenger to hold it or a mount for it. Getting the app to take an accurate measurement was a bit tricky as the car must be at a complete stop when you start recording and it seems to take a second to begin measuring after you press start.”

“…Does this mean the M Power Meter is inaccurate? Not at all, it just means we’ll have to take it with us the next time we go to the track and make a couple of extra runs against the VBox to find out…” (1)

The M Power Meter App can be downloaded from the Apple App store and features three free design skins: “Sport”, “Lava” and “Midnight”.
