Comparison between Fitbit Inspire 2 and Fitbit Inspire 3.

Let's take a closer look at the differences between the two fitness trackers in detail. Let's see which tracker is better for you and whether a switch might be worth it for you.


In terms of design, a lot has changed between the Fitbit Inspire 2 and Inspire 3. Overall, the successor is wider and longer built. In return, the Inspire 3 has become somewhat thinner. The thickness of the Fitbit Versa 4 and Fitbit Sense 2 has also been reduced compared to their predecessors.


The display differs tremendously when comparing the Fitbit Inspire 2 and Fitbit Inspire 3. The Fitbit Inspire 3 has a color display with an always-on option as well as a light sensor. The Inspire 2 still had a monochrome display, which in today's fitness trackers really no longer meets the current standard.

Does the Fitbit Inspire 3 have GPS?

Both fitness tackers from the comparison have only connected GPS and no integrated GPS. This makes the Fitbit Inspire 2 and Fitbit Inpsire 3 among the few Fitbits without built-in GPS.

Connected GPS means that the fitness trackers use the GPS from your smartphone. Thus, you need to carry your smartphone for recording GPS always with you.

Does the Fitbit Inspire 3 have a SpO2 sensor

Yes, new to the Fitbit Inspire 3 is the SpO2 sensor, which was not available on its predecessor. This sensor is used to measure or monitor oxygen saturation. By monitoring the oxygen saturation of the blood, the fitness tracker can detect and report health changes.

Heart Rate Measurement

Heart rate measurement has become a standard feature of fitness trackers, thankfully. Models without a measurement of heart rate are also relatively useless in my eyes.

Both the Fitbit Inspire 2 and Fitbit Inspire 3 have a heart rate measurement. However, only the newer Fitbit Inspire 3 gives out messages at high or low heart rate.

An ECG offers in comparison neither the Inspire 2, nor the Inspire 3. However, this is also little surprising.

Counts the Fitbit Inspire 3 floors?

No, furthermore the Fitbit Inspire 3 does not have a height sensor. Thus, the two fitness staplers do not differ in this point and both can not count floors. In my opinion, also not the most important point. Especially in high or oppressive temperatures, counting floors does not work very reliably either way.

Fitbit Pay

In comparison, neither fitness tracker offers Fitbit Pay. Also, no Google Wallet or Google Maps has been announced for the Fitbit Inspire 3. This is a special feature of the new Fitbit Versa 4 and Fitbit Sense 2 models, so you can't make contactless payments with either the Inspire 2 or its successor.

Which Fitbit Inspire is better?

Clearly, the Fitbit Inpsire 3 from 2022 is a lot better than the Fitbit Inpsire 2. When buying new, I recommend you direk to buy the Fitbit Inpsire 3*, which does not have a big surcharge. The predecessor, Fitbit Inspire 2*, looks much inferior due to its monochrome display. Zumdem you have to do without the SpO2 sensor in the Fitbit Inspire 2.

The differences between the Fitbit Inpsire 3 and Fitbit Charge 5 become so geinger. For the relatively low price, the Fitbit Inspire 3 is really a good fitness tracker.
