The Fitbit One is a clip-on based fitness tracker with a 1 inch monochrome OLED display, compatible with iOS, Android and includes, Step counting, Sleep tracking, and Calories.

Unfortunately, the Fitbit One has been discontinued. There are some retailers who still have some to sell, but you'll have to look around. Knowing Fitbit, there is always something new coming. I know the Zip is still around, but it doesn't have all the features of the One.

The One is typically worn clipped to a waistband or pocket, thus making it practically impossible to trigger false steps by movement other than walking. This model was also dead on in our step and distance tests, where we compared it to a manual count and measurement over multiple trials, averaging only 0.1% off.

Experts consider Fitbits surprisingly accurate, but they're not perfect. Because movement is subject to different factors, they're known to undercount or overcount steps at times. Walking on a plush carpet or pushing a shopping cart or stroller may cause Fitbit to undercount steps.

A: It is not really waterproof but I can say that it has survived an accidental dip in the lake after a canoe tip and my sister put hers through the wash and it is still going, btw a full cycle through the wash and dryer and less steps than a half marathon.
