BMW has launched the M Power iPhone app, the Bavarian automaker's second free application to promote its brand. However, unlike its previous offering, this app is actually sort of useful.
The M Power app measures vehicle acceleration using your iPhone's (or iPod Touch's) built-in accelerometer. After securing the iPhone (via a windshield mount or just tossing it in a cup holder), the app will measure 0-60 mph times other user-customizable speeds in mph or kph. The app will also measure forward and lateral G-forces for users who want to take a spin on a skidpad. Users can also unlock different skins on BMW's Web site to customize the look and feel of the app.
Although branded with the BMW M badge, the M Power app will work for any car that you can fit an iPhone into. Unlike my favorite paid iPhone accelerometer-based speed computer, Dynolicious, BMW's app doesn't look like it will calculate your vehicle's horsepower or torque. But at the low cost of "free," the M Power app is a hard bargain to turn down.
