I tested the Fitbit Inspire 2 against a scientific EEG device, and tested the heart rate and step counting accuracy.

This is the first Fitbit I have used. It has some new features kzfaq.infoUgkxbkrje8Y7BaqRkAjimw-55ajvVo7RbcIp and I like the information that it gives me.I think the phone app could be designed to be a bit more accommodating, as it can be confusing to use. The rubber band is comfortable, and normally I do not like rubber bands for my watches, but this is comfortable.I am looking forward to seeing if this helps me stay accountable in my fitness endeavors!My only gripe is the box was very damaged when it arrived, however, the tracker is performing perfectly!

Thank you so much, Rob! I waer a Fitbit Alta HR for several years and always have issues with my heart rate measuring (I use a Polar H10 to compare my HR while running). The measuring differs up to 25-30 higher while training which is a lot - nonetheless I am a huge Fitbit fan and your test gave me the last push to try out the Inspire 2. Used your affiliate link to support your channel. 🙏

Great video! One suggestion: on the HR scatter plot, perhaps you could make the data points from the weight lifting activity a different color dot compare to the cardio activities. Or even make a separate scatter plot with just the cardio (cycling/running) activities. It seems like most of the mismatch is from weight lifting which it appears most optical wrist trackers don’t capture. Thanks!

@sammyt3514 3 жыл бұрын

The Inspire has basically the same functions as my Fitbit Alta HR (could be the same internal parts in a different casing for all we know!), which I tested against the full professional sensors used on me during a sleep study and found to be remarkably accurate compared to the results of that sleep study. Of course, my comparison was basically comparing the amount of time I spent in each phase, which was roughly the same, so it wasn't nearly as detailed an analysis as Rob used in this video, but they were impressive all the same.
