Getting to know your Fitbit One
This section tells you how best to wear and recharge your tracker.
Placement
The One is most accurate when worn on or very close to your torso. A clip designed
to keep the tracker secured to your clothing is included in your package.
A sleep wristband for your One is also included in your package.
To avoid losing your tracker, we recommend that you wear it in your pocket, clipped
to your pocket, or clipped to your bra.
The One is not designed to be worn in direct contact with the skin. Always use the
silicone holder when clipping it to a bra or waistband, with the display facing
outward. Do not wear the One inside your bra.
Some users may experience skin irritation even when wearing the One as instructed
on the bra or waistband. If this occurs we recommend clipping it on your pocket,
belt, or other external piece of clothing.
The One is sweat-proof and rainproof. It is not waterproof and should not be taken
swimming.
Changing the display for left-handed use
By default your tracker is oriented for right-handed individuals. If you're left handed,
you can reorient the display to make it easier to read. To do so, log into your
fitbit.com dashboard and click the gear icon in the upper right. Click

Devices
and then find and adjust the
Left-handed
button.
Battery life and charging
The One is powered by a rechargeable built-in battery. Your fully charged One has a
battery life of up to two weeks.
