While a pedometer only counts steps, an accelerometer provides information on the total volume of physical activity, including the number of steps, as well as detailed information about the ...

Overall, the authors noted that heterogeneity was “high” for pedometer use and “moderate” for accelerometer use. Among the pedometer-based interventions used, the study participants reported an ...

"With an accelerometer, motion is much more precise," Fitbit CEO Park says. "A pedometer, for instance, uses mechanical mechanisms for counting steps.

For the extra size, you do get some features. For one, there is a 16×2 LCD display and an ADXL335 accelerometer, and you can probably imagine some other cool features for such a device.

This pedometer style counter uses NASA-esque technology to calculate your physical activity and how many calories you're burning. Just enter your weight, clip the Accelerometer to your belt and ...

With it, via I2C, I could add an Arduino Pro Mini, and an I2C Oled Display and make a watch capable of having all this information, plus a pedometer (by analysing accelerometer data).
