Common Questions:

Who is the FitBit One a good fitness tracker for?

The FitBit One is recommended for everyday fitness by FitBit. This essentially means that this device is just for any person to wear around and track what they do. It isn’t meant for “active fitness” or “performance fitness,” which are the other two FitBit product classifications. So basically if you are planning on using this to monitor your active excercise, you might want something else. This is more something to wear around all day, including while sitting at a desk.

Can I share stats and compete with friends with the FitBit One?

Yes, you can share your data and compete with friends by  syncing your FitBit One with your mobile device or computer. Sharing is completely up to you, but if you compete with friends it might motivate you to do more or take those extra couple steps each day. FitBit tries to make the competition feel friendly. You can also send people messages.

What is the difference between the FitBit One and the FitBit Zip?

The FitBit One has the ability to track your sleep quality and also includes a silent alarm. The FitBit One also tracks floors climbed. There is a button on the One that lets you scroll through stats. This added functionality means the One is more expensive than the Zip, typically around 50% more (that is what it was at the time of writing). Find out more in our FitBit Comparison.

What is the difference between the FitBit One and the FitBit Flex?

The FitBit One and FitBit Flex both are typically the same price, and so people are confused about the differences. The two devices are actually quite different. The One is a clip on device that has an OLED screen to display a few of your fitness stats. The Flex has no such screen and must be synced with another device for you to see your stats. The Flex also is a wristband, so you don’t need to clip it onto anything, which could make it easier to wear.

What comes in the box with the FitBit One?

What Others Are Saying:

Jill Duffy, PC Mag:  “The Fitbit One is a sleek, sturdy, and affordable device that can help you monitor your physical activity and motivate you to increase it. It’s the best fitness gadget on the market for non-athletes.”

Bethany Gordon, TopTenReviews:  “If you’re looking to start making healthy choices, the Fitbit One encourages you to get up and move, and it is highly compatible with all your peripherals.”

Brent Rose, Gizmodo:  “If you’re considering the Fitbit Zip, then sure. It’s certainly better, due to the altimeter, improved screen, and recharability. And the silent alarm is a cool feature.”


The FitBit One is a clip on device that can be worn in a wrist band. A lot of reviewers seem to label that as a bad thing, but you have to realize that this type of device is built intentionally for people looking for exactly that, a clip that can go in a wrist band or clip anywhere. If you want something to wear on your wrist all day or all the time, this isn’t that (consider the FitBit Flex instead). However, if you want a device that you can clip somewhere on yourself during the day, and you have the option of wearing it at night, then the FitBit One might just be for you.

This device really stands out in the clip-on fitness tracker market as it is the most expensive clip-on, but also the one with the most functionality. You get a nice OLED Display and of course get to use the great FitBit app, which works on lots of devices. The battery in this device also is pretty good, lasting up to 14 days.

The negatives are that the device isn’t perhaps that comfortable to wear (although no clip-ons really are), it only comes in two color options (pink or black), there are no phone alerts, and there is no optional heart rate capability.

If you are looking for the best clip on fitness tracker, the FitBit One might be the device for you! If you are only considering the One based on price, check out our comparison table of the best fitness trackers under $100.
