– New sensor: This now has 5 LEDs (3xGreen, 1xRed, 1xInfared) compared to the previous 2xGreen. Here’s what’s new in Whoop 4.0 versus Whoop 3.0: Since I cover all of this stuff in far more depth in this post, I’m gonna keep this section as brief and to the (bullet-)point as possible. Oh, and I also bought a bunch of Whoop Body stuff too, to test, also in this review.) What’s New in 4.0: That’ll go back to them shortly, and I’ll just keep the one I own. Back in October, while that was happening, Whoop also delivered a 4.0 media-loaner unit to get started on testing.
#BAND IN A BOX 9.0 REVIEWS UPGRADE#
(Note: I bought this unit myself, in that I’m a paying Whoop subscriber, and thus, I reserved my upgrade early and waited a while. A lot of nuances, and a lot of things to digest. Therefore, that brings us to one singular question: Is Whoop 4.0 finally accurate? For that, there’s a lot to talk about. And given the entirety of Whoop’s data is based on heart rate sensing, all further calculations were just hot air.īut 4.0 promised significant steps in its accuracy. It was objectively horrible – not just by my tests, but by virtually every trusted reviewer in this space. And the sum total of Whoop 3.0 is that it was arguably one of the worst mainstream optical HR sensors ever made. Some 400+ workouts, each with 2-4 other heart rate sensor devices. In fact, I’d take a pretty safe wager that nobody on this planet has as many comparative workout sets (in terms of quantity of comparative HR sensor devices per workout in total) than I do with respect to Whoop. It doesn’t even let those two Whoop pillars of functionality (training & sleep) mix much in its grading of your results for each pillar.įor those semi-long-time readers, you’ll know I started testing the previous generation Whoop 3.0 nearly two years ago. It’s not a daily step counter, nor a smartwatch with a display, nor an activity tracker.
Stepping back to basics though, Whoop’s purpose in life is to try and figure out whether or not you’re training too much or too little, and whether or not you’re sleeping too much or too little.
Inversely, if it’s accurate – then we can dive deeper into whether there’s value in the greater Whoop platform, given its pricing of $30/month (albeit substantially less if you buy it in 12 or 18-month chunks). Thus, if that heart rate sensor is inaccurate – absolutely nothing else in Whoop’s app matters. See, the entirety of Whoop as a platform revolves around that heart rate sensor. But the real difference you (should) actually care about is the change to the heart rate sensor itself.
#BAND IN A BOX 9.0 REVIEWS SKIN#
Sure, it now includes both skin temperature as well as SpO2 sensors. While the new Whoop 4.0 looks physically similar to the previous 3.0, it’s a significantly different beast of hardware. It’s been a few months since Whoop announced their new Whoop 4.0 sensor, and after enough use for me to call this review ready – it’s time to dive (deep) into the details.
