Sorry but it doesn't even work well as a pedometer. I've done 30 minutes on the treadmill, 30 minutes on the elliptical, and 30 minutes on the stationary bike, and none of them registered. It is registered when walking IF you swing your arms. Curiously, this is recorded as walking while seated and rocking in a rocking chair. If the price was $20 I wouldn't be surprised but at this price I would expect more. Oh, one star was for the timing feature. At least the clock works!
