Fitbit Sense vs Versa 3 & Versa 2 vs Apple Watch vs Garmin Venu & Vivoactive – Fitbit finally get their act together

Yesterday Fitbit announced their latest 2 smartwatches, finally embracing built-in GPS, making them both viable alternatives as sports watches compared to many brands.

Both watches look good, but I think the Versa 3 may struggle due to competing options. The Fitbit Sense is the star of the show, while it may be quite expensive; it offers a range of features that competing brands don’t.

In particular, there is the skin temperature sensor on the wrist, which no one else currently offers, they have also upgraded the optical HR sensor and the watch can now offer heart rate, ECG, breathing rate, Heart Rate Variability (HRV), SpO2  and electrodermal activity.


Last year some health tracking features such as SpO2 didn’t really offer a great deal of useful functionality. Your lungs tend to be OK or not OK, and most of the time, you will know one way or the other. It can be useful for a handful of conditions such as sleep apnea, though.

With COVID-19 things have changed. SpO2 levels are affected by  COVID-19, so in theory, this can be a variable used to identify infection. Skin temperature is a symptom of many viruses and this again can be used as an early warning for COVID-19.

No company has come out with any specific COVID-19 tracking/early warning feature, but Fitbit has talked about their prediction capabilities around illness, and it is likely that these tracking features will be a major selling point for the Sense.


The first Fitbit watch was the Ionic, and this came with GPS built-in, they then ditched it for the first two Versa watches.

Thankfully it is not included with both the Versa 3 and Sense. This is an important feature for me, and most people serious about fitness tracking, and it brings the two watches inline with pretty much every other fitness or smartwatch available on the market (that’s how stupid it was to not include it with the Versa 1 & 2).

Battery Life

Fitbit claim over 6-days battery life for both watches, which is quite important because it offers them one significant advantage over the Apple Watch S5 and S3.

It also makes them comparable to Garmin, though they Vívoactive 4S has 7 days battery and 8 days for the Vívoactive 4.  The Garmin Venu lasts a little less at 5 days
