Fitbit One Review

The design of the Fitbit One, a popular fitness tracker, is compact and user-friendly. When comparing its design to other fitness trackers, the Fitbit One stands out with its small and oval-shaped design, making it easy to carry. It features a clippable design that can be attached to clothing, providing convenience for users.

However, there have been reports of the clip coming loose and causing the device to be lost, which may be a drawback for some users. Additionally, the Fitbit One is not as convenient or secure as wristband-style devices.

Despite these limitations, the Fitbit One is still highly portable and lightweight, easily clipped to clothing or slipped into pockets. However, there is a risk of losing the device when using the clip, especially with large messenger bags. It is important to note that accidental washing of the device is also a concern.

Usability And Setup

Continuing the discussion from the previous subtopic of design, the usability and setup of the Fitbit One fitness tracker are crucial aspects to consider. Here are three key points to note regarding usability challenges and the setup process:

  1. Intuitive Interface: The Fitbit One features a straightforward interface with a single button to toggle through different screens. Users can easily navigate and access various functions without much complexity.
  2. Setup Process: Setting up the Fitbit One is relatively simple. Users need to create an account on Fitbit’s online service, download the companion mobile app, and follow the step-by-step instructions to sync the device with their smartphone or computer. However, some users have reported minor issues with Bluetooth connectivity during the setup process.
  3. Usability Challenges: While the Fitbit One offers a user-friendly experience overall, there have been some reported challenges. These include occasional syncing problems, inaccurate sleep tracking, and the clip design sometimes coming loose, leading to the risk of losing the device.
Fitbit One Review


The Fitbit One is a clip-on fitness tracker that is very small and simple, which is why it did so well on our posture test. With an 8 out of 10, this tracker tied for the best score in this area. When clipped into your pocket or belt, this model is so small and light that you almost forget you have it on.

With its small, plastic square shape that looks a lot like a USB flash drive, this model’s design is about as straightforward as it gets.


We finally looked at these goods’ display quality as the last thing we did. The Fitbit One got a 6 out of 10, which is a little better than normal. The smaller screen on this model doesn’t show a lot of information, and it’s not even close to high definition, but it does a good job of showing you the basics.

It’s a little hard to read this model in bright sunlight, but it works fine when there isn’t much light. We liked that this model responds very quickly when the button is pressed, which is different from other models that can be very hard to wake up. On the One, there are no smart notifications for calls or texts. Instead, it gives you fun, personalized motivation throughout the day to help you reach your exercise goals.


Moving on to the topic of value, there are several factors that contribute to the overall worth of the Fitbit One fitness tracker.

One of the key considerations is battery life. A rechargeable battery that powers the Fitbit One typically lasts a full work week without needing a power boost. This is a significant advantage, as it ensures that the device can be used consistently without the need for frequent charging.

Additionally, the Fitbit One offers good connectivity options. It can connect to PCs and Macs using a USB Bluetooth adapter, as well as link to smartphones over Bluetooth. While compatibility with smartphones is currently limited, Fitbit plans to expand Bluetooth communication with the Android app to include more phones. This enhances the device’s versatility and usability, further adding to its overall value.

Fitness Impact

Fitbit One Review

Our most important and weighted parameter, fitness impact, is critical for this product category. The Fitbit One scored 7/10 in this area. We rated each tracker based on its ability to calculate stairs climbed, count steps, track cycling and a high-intensity cardio workout, and track other physical activities. We also examined each device’s community and how you could compete with pals.

The step counter on these items is popular since many individuals aim for 10,000 steps a day. We tested many trackers, but this model was the most accurate. Wearing the One clipped to a waistband or pocket makes it nearly impossible to trigger false steps by movement other than walking. This model averaged 0.1% off in our step and distance tests compared to a hand count and measurement over several trials.

For more competitive users, you can cheer for or insult your pals and check their top badges. Facebook integration allows you to find friends with this model.

This model only tracks running, walking, and hiking; other activities require human data entry on the website. We tested this model and it calculated stairs climbed well.

Health Impact

The second most critical test metric is health effect. Health effect includes heart rate, diets, motivation, and sleep tracking, however it is closely related to the previous metric.

Fitbit One Review

Fitbit One dropped to 5 out of 10 in this area. Without heart rate monitoring, this model falls behind the leaders in this statistic. This model estimates resting metabolic rate (rMr) calories burned throughout the day, helping you improve your diet. We projected rMr for our tester using a basic method and this tracker was accurate.

The accompanying wristband lets you wear this tracker while sleeping. This model tracked sleep averagely, mirroring our tester’s restlessness and wakefulness. Sleep tracking requires a button press.

This device wakes you up softly with a vibrating alarm but doesn’t remind you to exercise if you’ve been idle. This model has no extra features other than a flower emblem to show your progress toward your objective.
