Yesterday (September 08th, 2021), Whoop announced its all-new fitness device, the Whoop 4.0. The device is 33% smaller than its predecessor. However, it is packed with five LEDs, four photodiodes, a pulse oximeter, a skin temperature sensor, and more.
One of the most significant developments with the Whoop 4.0 is the result of Whoop’s dedication to making a wearable that is truly wearable. Using the catchy slogan “it’s not a watch, it’s a Whoop,” the Whoop 4.0 can be worn on your wrist as a traditional fitness tracker but also in various items of Whoop apparel. This includes boxers, bralettes, leggings, and performance tops.
So let’s have a look at what we know so far…
Whoop 4.0 Design
As we have already mentioned, the Whoop 4.0 is 33% smaller than the Whoop 3.0. That is pretty much where the design differences change. However, if you plan to use it hidden in boxers or bralettes, it doesn’t necessarily need to be the most stylish.
There has also been an upgrade to the bands. This isn’t a surprise. The Whoop 3.0 did receive some negative feedback regarding the bands’ amount of time to dry. SuperKnit bands now come as standard that Whoop says is comfy enough to be worn 24/7 yet durable enough to deal with day-to-day life. There are also plans to release a quick-drying, HydroKnit band aimed at those wanting to use the device in water.
This is where things get really interesting; there is a lot to talk about. Firstly, the device is now waterproof, a massive plus for many users.
Another criticism common with the Whoop Strap 3.0 was the lack of accuracy when monitoring heart rate etc. Whoop certainly took notice as there are now five LEDs on the underside of the device – three green, one red, and one infrared.
Furthermore, skin temperature and blood oxygen will also be tracked. Heart rate monitoring includes continuous tracking, resting heart rate, heart variability, and respiratory rate.
On the wellbeing front, the Whoop 4.0 includes a range of personal coaches such as a strain coach to help avoid under or over-training. A sleep coach that can wake you when you have reached your optimal sleep time and a behavioral journal enables you to track behavioral patterns such as diet, stress levels, and caffeine intake. This can be used to see how specific patterns of behavior affect your sleep and training schedules.
Whoop 4.0 Battery
The most significant development of this device is the all-new battery design. The Whoop 4.0 is the first tracker ever to use Sila’s new silicone anode battery. There is a lot of tech speak behind this development, but the result is a longer cycle life and higher energy density. Consequently, despite the addition of multiple sensors, the Whoop 4.0 can still provide the same five-day battery life as its predecessor.
Further good news is that Whoop has also made the portable battery pack waterproof. The battery pack has always been a great feature of Whoop’s devices. Being able to charge your device without actually taking it off has several advantages.
As we mentioned above, the Whoop 4.0 is designed to be used on your wrist and with Whoop’s new range of apparel. Whoop has said that all garments are designed to hold the device as close to the body as possible. Furthermore, with their new “Any-Wear” technology, the device can identify whereabouts on the body it is being worn. Apparel available from Whoop currently includes:
- Compression tops
- Sports bras
- Athletic Boxers
- Regular Boxers
Whoop 4.0 Price and Availability
As you may or may not know, Whoop provides a membership platform, and unfortunately, you can not get your hands on the Whoop 4.0 without being a member. Those that are already members and have at least 6 months left on their membership will receive a free upgrade to the Whoop 4.0. Otherwise, you will need to choose the membership package that best suits you to get the device for yourself.
Whoop expects to start shipping from the last week of September.
