The new Whoop 4.0 is now available

Whoop, the company behind the performance-focused watch trusted by some of the biggest names in sports, has unveiled its next-generation tracker. This is Whoop 4.0.

The Whoop Strap 3.0, which launched in 2019, can still be worn inside a knitted band and still requires a monthly subscription. This provides access to rich information on sleep, recovery and training.

The Whoop 4 offers several improvements

Whoop claims its new device is 33% smaller than its predecessor. It now includes a pulse oximeter to monitoring blood oxygen levels and a skin temperature sensor. SpO2 is now standard on smartwatches and fitness trackers from Fitbit, Apple and Samsung.

Temperature tracking, on the other hand, is less common; Fitbit being the only major player to have adopted this technology in a significant way.

It also boosts sleep functions with a new sleep coach. It uses haptic alerts to wake you up at optimal times based on sleep cycles and sleep time guidance.

Battery life is the same as the Whoop Strap 3.0 at 5 days.

Along with new sensors, the Whoop 4.0 has “enhanced sensor configurations”. They should measure heart rate more accurately. It’s good news. Indeed, despite its place in my ranking of the best heart rate monitors, the optical heart rate monitoring of the Whoop Strap 3.0 was not precise. It was far from 100% reliable for all exercises tested.

I find moving it up the arm in the bicep sleeve that Whoop provides more. It improves accuracy. It’s clear that Whoop also acknowledged this fact. The Whoop 4.0 is also accompanied by a new range of Body clothing. This will allow you to wear the device in more places on the body.

The Body collection is divided into two ranges: Training and Initimate. The first including sports bras, leggings, arm warmers and shorts. The Intimate range includes briefs and bras.

The Whoop 4.0 is available with the same subscription and the new Body garments as well as the SuperKnit and HydroKnit bands will only work with the new Whoop.
