Whoop, the company behind the performance-focused wearable favoured by some of the biggest names in the sporting world has unveiled its next generation tracker. It’s called the Whoop 4.0.
The follow-up to the Whoop Strap 3.0, which launched back in 2019, can still be worn inside of a knitted band and still requires a £19 monthly subscription to gain rich sleep, recovery and training insights. With 4.0, you’re now able to track from different parts of the body, which explains the move to drop Strap out of the name.
Essential reading: How Whoop is taking inspiration from Nike
Whoop says its new device is 33% smaller than its predecessor and now includes a pulse oximeter to monitor blood oxygen levels and a skin temperature sensor, which are sensors that have already appeared on smartwatches and fitness trackers from the likes of Fitbit, Apple and Samsung.
It’s also bolstering sleep features with a new sleep coach that uses haptic alerts to wake you up at optimal times based on sleep cycles and sleep time advice. Quoted battery life is the same 5 days delivered by the Whoop Strap 3.0, so there’s no improvement on that front unfortunately.
Along with new sensors, the Whoop 4.0 has ‘upgraded sensor configurations’ which it says should lead to more accurate heart rate measurements. That’s good to hear because despite grabbing a spot in our rundown of the best heart rate monitors, the optical based heart rate monitor on the Whoop Strap 3.0 wasn’t 100% accurate or reliable for all exercises we tested it out with.
We actually found moving it up the arm into the bicep sleeve Whoop additionally offered, improved accuracy. Clearly Whoop has recognized this as well, as the Whoop 4.0 is also joined by a new Body garment range, which will allow you to wear the device in more places around the body.
The Body collection is split into a Training and Initimate ranges, with the former including sports bras, leggings, arm sleeves and shorts. The Intimate range includes boxer shorts and bras.
The Whoop 4.0 is available on the same £19 a month subscription and the new Body garments along with SuperKnit and HydroKnit bands will only work with the new Whoop.
If you’re a current Whoop member, you’ll have first access to Whoop 4.0 through a free upgrade.
It’s been a busy time for Whoop who recently announced it acquired Push, the Canadian startup that launched the Nexus and Push Band wearables designed to help better track weighlifting and CrossFit workouts.
We’ll be testing out the new Whoop and some of its new garments to see if this is a wearable you need in your life.
