I would be the first to confess I used to be doubtful in regards to the Whoop 4.0. In brief, a fitness tracker with out a display sounds rather a lot like a glorified bracelet. Nonetheless, after practically a month strapped into Whoop’s ecosystem, I humbly admit I’m altering my tune. The Whoop 4.0 hasn’t solely satisfied me a display isn’t mandatory, it has me questioning if I need to return in any respect.
About this text: I examined the Whoop 4.0 for over three weeks. The unit was offered by Whoop, however Whoop had no say within the course or printed content material.
A really fashion-forward wearable

In a market oversaturated with choices, the Whoop 4.0 is a novel machine. Its minimalist design features a small, light-weight tracker (roughly 33% smaller than the Whoop 3.0), a cushty knit band, and a metallic clasp. No colourful AMOLED show, or perhaps a black and white LCD one. No display in any respect. Which means no notifications, on-screen stats, or distractions, and all these omissions have a pleasant impact.
For starters, the Whoop 4.0 is solely handsome. The Luxe bands specifically are genuinely engaging, and I obtained a lot of unprompted, optimistic remarks all through my testing interval. Contemplating I wore my band through the Thanksgiving holidays, I used to be grateful for the go-to icebreaker throughout household small discuss. “Ah sure, that is the Whoop 4.0, I’ve a reasonably blue strap for it again on the resort too!”
With no flashy display and animations, the Whoop strap gives a stark distinction to lots of the hottest wearables. It doesn’t simply mix in together with your wardrobe, it accents and elevates on a regular basis put on. With that intent, Whoop sells an enormous vary of colorways so discovering a band that matches your fashion is straightforward.
Loads of trackers tout swappable bands for mixing up your look — I’ve a number of Apple Watch bands however not often differ from my go-to nylon staple. In distinction, throughout this evaluation interval alone, I swapped my Whoop band at the least a dozen occasions. An entire sucker for something inexperienced, I wore my Ivy possibility with its stylish gold clasp essentially the most. Throughout USA World Cup video games, I swapped into the blue equipment for good luck (it didn’t work). The usual black I reserved for sweaty runs and hikes. In brief, the Whoop band feels rather a lot much less like a tracker than a customizable accent. The bands aren’t low cost ($49-$99), however it is going to doubtless really feel definitely worth the splurge.
With no show, the highly-customizable Whoop 4.0 is a chic accent for on a regular basis put on.
It’s additionally simply essentially the most comfy wearable I can bear in mind testing. Contemplating it’s designed to be worn 24/7, that shouldn’t be stunning. Nonetheless, tons of trackers make the identical declare, and that is the primary I’ve discovered to very practically stay as much as the hype. The exception I encountered was a private choice. I attempted to put on the band within the bathe, and post-rinse, the moist strap gave me the heebie-jeebies. Fortunately, the crew at Whoop despatched me various bands so I used to be in a position to swap right into a dry possibility.
If, nonetheless, you’re unusually comfy sporting what seems like a moist sweatband for just a few hours, you can theoretically hold your machine on nonstop. It’s water resistant to depths of ten meters (a lot deeper than my bathtub) for up two hours and protected for swimming in chlorinated water or salt water.
A battery constructed for all-day put on
Like previous generations, the Whoop 4.0 is meant to stay in your wrist, together with whereas charging. The upgraded battery pack is even waterproof and might be a part of you and your Whoop band throughout a bathe if that’s ever mandatory. A swift double faucet on the battery will show its cost degree. A crimson standing gentle means you’re low and a inexperienced one means you’ve gotten juice left within the tank.
The strap is designed to be worn 24/7, together with whereas charging, so customers by no means miss essential information.
I discovered it most handy to cost throughout work hours because the pack is light-weight and secures on nicely sufficient for typing away at a pc. The band provides off an actual bulky-turtle vibe with the battery hooked up, so I wouldn’t make a behavior of leaving the home with it clipped on anyway. Plus, a substitute battery prices $49, which is not any small charge in the event you lose it whereas out and about.

The battery pack itself fees through the world’s shortest USB-C cable. As a neat freak who loathes twine nests, I genuinely admire the utilitarian design. I left my battery plugged in all through the Whoop evaluation interval (outdoors of the time it spent on my machine) and it didn’t disrupt my desk house within the slightest. As soon as on the tracker, the battery charged the machine in simply over two hours. Every cost lasted me about 5 days. Once more, practically per week between fees is extraordinarily handy and an enormous advantage of skipping out on a power-draining show.
And in addition all-night put on
One other unexpected plus of the screen-free wearable is disruption-free sleep. Regardless of sleep modes and preset schedules, I’m usually distracted by my smartwatch in mattress. If I’m not being woken up by a shiny display, I’m already awake, disabling sleep mode to ship one final trivial textual content.
Not solely is the Whoop 4.0 comfy sufficient to put on whereas sleeping, however it precisely tracked my sleep. The most recent mannequin added SpO2 monitoring in addition to a temperature sensor, and each are leveraged for in a single day information. It was spot on for sleep and wake occasions, and my sleep levels aligned carefully with my Fitbit Versa 3, a notably correct sleep tracker. As with different information units within the Whoop app, I admire how well-organized sleep evaluation is offered. Since these options are largely carried over from the earlier mannequin, I gained’t go into an excessive amount of element.
The band is a really correct sleep tracker, and Whoop efficiently turns your sleep information into actionable insights.
Personally, I discovered the Journal characteristic of Whoop’s sleep-tracking suite fairly helpful, though the every day immediate is considerably aggressive. “What occurred yesterday?” instantly will get my coronary heart fee up. As earlier than, customers can specify what behaviors they need to report after which analyze how these behaviors have an effect on their sleep over time. I noticed predictable traits when it got here to caffeine and alcohol consumption, however I used to be considerably shocked to see how a lot my sleep correlated with hydration and sure psychological well being elements corresponding to gratitude, out of doors time, and social success.
This side of the Whoop expertise is a superb instance of how an unobtrusive tracker can present very actual worth when paired with a sturdy app. The sleep insights Whoop gives are straightforward to translate into sensible adjustments.

Whoop cuts out plenty of the main points that may flip health monitoring into an obsession with stats as an alternative of an avenue for wellness. Nonetheless, athletes who depend on real-time information corresponding to tempo, distance, or coronary heart fee zones is not going to be followers of the screen-free wearable. Likewise, out of doors fans searching for navigation instruments and onscreen mapping also needs to store elsewhere. If you happen to usually have to know the time, Whoop can’t aid you both.

The Whoop band presents completely no on-wrist advantages past aesthetics and a surprisingly efficient alarm. (The haptic is new on this era, and, if enabled, will wake you through the optimum sleep cycle.) Every thing else occurs within the app, the place Whoop emphasizes the steadiness between how exhausting you’re employed and the way your physique recovers.

Exercises may be uploaded to Strava, and you can too broadcast Whoop’s coronary heart fee information to third-party apps and gadgets like Peloton.
As the road between health trackers and smartwatches continues to blur, the Whoop strap stays a uncommon instance of pure monitoring. It’s not providing to make telephone calls, play music, or make contactless funds, and actually, it’s form of good. Many people are so emotionally hooked up to our telephones, a second display hooked up to our our bodies isn’t mandatory. Will I am going again to Apple or Garmin? Sure, most likely. However this month has been a refreshing reminder that connectivity may be exhausting, and that on-screen metrics are typically fairly draining. The Whoop 4.0 presents an alternate.
