Whoop 4.0 features an updated sensor configuration that provides more accurate readings, and during our testing, we didn’t see any drops in measurement accuracy from our time with the Whoop 3.0. While the physical improvements to the 4.0 are great, Whoop made upgrades to the tracking and app that makes the new strap even more in-depth and easier to use. Whoop’s core of strain, sleep and recovery is still stellar
That full charge will give you about five days of juice, so you don’t have to worry about charging it all the time. Thankfully, Whoop has kept the same battery life for both the sensor and the detachable battery, meaning it takes about two hours to charge the pack and an hour and a half for the pack to charge the strap.
In fact, it’s about the size of a standard smartwatch. The battery pack still adds some bulk to your wrist since it slides onto the strap to charge, but even with it attached, the Whoop 4.0 doesn’t feel bulky. This was a massive game changer for us because now if you accidentally forget to take the battery off your strap while you’re washing your hands or doing the dishes, you won’t need to worry about it breaking. On top of these upgrades to the band itself, Whoop has also created an all-new waterproof battery pack. Instead of unhooking both sides of the clasp from the sensor like you would on the 3.0, the 4.0’s clasp easily slides off so you can spend less time taking your old strap off. The material of the strap feels much better than the old version, with a smoother, softer design. Whoop has also reworked its strap and clasp system, which is what holds the sensor on your wrist. It’s much smaller and feels noticeably more comfortable. When we tested the 3.0, we didn’t really think it felt bulky on our wrist, but when we put on the 4.0 we immediately felt the difference. The Whoop Strap 4.0 improves on its predecessor’s design with a sensor that’s 33% smaller.
Amazon’s Halo and Halo View offer a similar formula, but rather than just providing more data, they toss in recipes and workout classes too.Ī welcome upgrade from the Whoop Strap 3.0 The other big difference, again, is that the Whoop Strap is a monthly membership compared to other trackers that you buy outright. Compared to other fitness trackers and smartwatches, it offers a deeper dive into your health that’s super useful in tailoring how you approach your exercise day by day, but the Whoop Strap 4.0 is purely for fitness. And if you already have a Whoop membership you can get the upgraded strap for free.
How it compares: The Whoop Strap 4.0 is definitely a worthwhile upgrade from the 3.0. You can join for $30 per month with a six-month membership or commit to a longer membership and pay as low as $18 per month up front, totaling $324. However, like the Whoop Strap 3.0, this fitness tracker requires a membership. The brand also released Whoop Body, a line of clothing that can hold your Whoop tracker so it doesn’t always have to be on your wrist.
What you need to know: Whoop Strap 4.0 is smaller and sleeker than its previous iteration with a few added features like skin temperature and blood oxygen readings as well as a haptic notification alarm function. However, if you’re an athlete or a fitness fanatic who craves in-depth data, the Whoop Strap 4.0 is for you. If you’re just looking for a strap to count calories and steps, a tracker like the Fitbit Inspire 2 will do the job.
Who this is for: The Whoop Strap 4.0 is for people who want to optimize their workouts and recovery. Your CNN account Log in to your CNN account
