How Can I Tell Which Fitbit I Have?

There is a good reason why Fitbits are one of the most popular smartwatches today. 

Other smartwatches do not provide the same level of convenience as Fitbit.

Fitbit is, for the most part, self-contained.

Some watches are required to be synced with phones or to be connected to a cellular data network. 

Fitbit has become increasingly popular over the past few years, resulting in hundreds of models being released. 

This makes it difficult to determine exactly which Fitbit you own. 

That does not mean, however, that it is impossible.

Find out the differences between each Fitbit model and which one you possess by reading on. 

How do I choose a Fitbit? 

Locating the model number on the back or side of the watch is the easiest way to determine the type of Fitbit that you have. There are five digits in the code, starting with FB, followed by three numbers. Your Fitbit model can be found by searching for that. 

Visual identification is also possible through an examination of images online and our description provided here.

The first Fitbit watch was released in 2009, and the company was founded in 2007. 

Due to the vast variety of Fitbits created since then, it can be difficult to know which Fitbit you own, especially if it has been with you for some time or if it is a gift. 

It is possible that you do not know the exact model of your Fitbit even if you have a current model. 

Moreover, Fitbit releases several models in a single year. 

We’ll make it easy for you to locate the particular Fitbit that you own. 

Read on to discover which Fitbit you own. 

Smartwatches vs. trackers 

Fitbit had two different kinds of products, despite looking the same. 

The other is a simple tracker that counts your steps, calories burned, and other workout data. 

Fitbit has also got a smartwatch with a lot of cool features. 

These watches have more features than something like an Apple Watch. 


There is a high likelihood that you have a tracker if your watch does not include features such as Amazon Alexa or sleep tracking. 

There are three Fitbit trackers: the Inspire, the Charge, and the newest Fitbit Luxe. 

Fitbit Inspire is a cost-effective tracker that offers several basic features. 

Typically, it comes in one solid color, but it comes in a variety of colors. 

Slender in design, it has one button on its side. 

With its wider, more square-shaped face, the Fitbit Charge is easy to use. The device is easy to identify since it does not resemble the typical Fitbit. 

This is the company’s latest fitness tracker, the Fitbit Luxe.

When it comes to appearance, it is a combination of the Inspire and Charge models.

If you find the Inspire too small or the Charge too bulky, then this is the perfect product for you. The Inspire has rounded edges, while the Charge and Charge HD have sharper edges. 

Smart Watches 

There are many features found in smartwatches that trackers do not possess. 

This includes voice recognition software such as Amazon Alexa and Google Assistant. 

So, to determine the type of Fitbit smartwatch you own if you have voice recognition, please read the following information. 

Fitbit’s Versa 2 smartwatch was released in 2019.

This watch has a square face with a button in the middle of one side. 

There is little difference between the Fitbit Versa 3 and the Versa 2. It can be difficult to discern the differences based merely on appearances. 

It is possible, however, to determine whether you have a Versa 2 or a Versa 3.

The 3 is equipped with GPS, while the 2 does not. 

A month after the release of the Fitbit Versa 3, Fitbit released the Fitbit Sense. 

Sense is very similar to the Versa but is considerably more expensive. 

The Sense is primarily marketed for its electrocardiogram function.

You can simply check to see if this feature is available. You know you have a Fitbit Sense if you see the electrocardiogram function. 

Discontinued and older Fitbit products 


There are dozens of Fitbit products, including clip-on trackers as well as devices that appear more like bracelets than watches.

The band on these devices does not have a latch but instead relies on elastics or rubbers to attach the device to the arm. 

This category of product includes the classic Fitbit Flex and earlier models in the Charge lineup. The Fitbit Flex was first introduced in 2013 and is considered to be one of Fitbit’s most iconic models.

This device was innovative for its time, monitoring sleep patterns and movement 24 hours a day. The wristband makes it easy to identify.

No clasp secures the device around the wrist. Instead, it is secured by a flexible, but stiff wristband. 

Based on the Fitbit Flex, the Fitbit Force was developed. 

An always-on clock was incorporated into this release at the tail end of 2013.

The product was recalled in 2014 after reports of allergic reactions. 

A year after the Fitbit Force was released, the Fitbit Charge was released as a replacement. 

Several of its features are the same as those of a Force, including a textured wristband that makes it easy to identify. 

Due to its larger screen, the Fitbit Charge 2 is easier to recognize than the original Fitbit Charge. 

Among the lineup, Charge 3 was the first to include an oxygen saturation sensor. 

Please check for an oxygen saturation sensor if you are not sure which Charge you have. 

This feature is not available on the original Charge or Charge 2. 

Spotify is now available for Fitbit’s Charge 4 trackers. 

The Charge 4 will be released in early 2020 if you have a Charge 3 that includes Spotify. 

Fitbit’s Alta features the well-known design of its original Flex.

It has, however, been significantly upgraded. 

The OLED screen of this device provides a brighter display. 

Like the Flex, the Fitbit Alta HR is a wearable fitness device. The device features an all-known sleep stage monitoring feature. 

Smart Watches 

The Fitbit Surge appears similar to the Fitbit Charge and Sense, however, its design is square and more angular. 

This watch may be easily identified by the fact that its band is of the same width as its face. 

Fitbit Blaze is designed to compete with other popular smartwatches. The Versa replaced it after a relatively short period on shelves. 

Its square face and multi-button layout make it easy to identify. 

The Fitbit Ionic differs from all other Fitbits in many ways. 

The watch’s face is sharp and square, and its wristband is roughly the same width as the face and becomes increasingly thin as it reaches the ends. 

Serial Number of Fitbit 

The serial number of the Fitbit you own can be found by looking up the model number. 

Most Fitbits make it easy to find the serial number inside the phone. 

Simply go to settings and find “Regulatory Information.” The serial number is a string of 12 or more characters. 

You can easily find out what type of Fitbit you have by searching for this serial number.
