Intro:
Over the last weeks I’ve extensively tested the new Fitbit Versa 4 alongside its more expensive brother, the Sense 2. And in this video we will take a comprehensive look at the heart rate accuracy, sleep tracking performance, GPS tracking and step counting accuracy of this brand new watch from Fitbit. As always, my videos are not about listing the specs, but instead we will focus on independent and unbiased performance testing of this new Fitbit Watch.

I did want to make two remarks before getting to the test results. The first is that this Versa 2 looks very similar to the Sense 2, and the main difference between the two is that the Fitbit Sense 2 has a few additional health features. Specifically, the Sense 2 can measure your electrodermal activity and help with stress management, it can also take an ECG measurement to potentially detect a type of irregular heart rhythm called Atrial fibrillation or AFib in short, and finally it will measure your skin temperature changes between nights, which could help you track your menstrual cycle, or the onset of a fever. The second thing I wanted to mention is the pricing; The Fitbit Versa 4 will set you back about 230 dollars, whereas the Sense 2 is slightly more expensive at 300 dollars. If you do decide you want to buy one of these two watches, I would base it on both the test results I am going to show you, and also if the additional features that the Sense 2 offers are something you would use. Now, let’s dive into the test results.

Overall the Fitbit Versa 4 did not impress me. Similar to the Fitbit Sense 2, it did not really feel like an upgrade compared to previous generations. The heart rate tracking was honestly pretty bad, and the GPS tracking was also quite underwhelming. The step counting was OK, though not great, since it counted quite some steps when it was not supposed to. The only thing I can really recommend it for is for sleep stage tracking; which is something that Fitbits seem to be good at in general.
