WHOOP 4.0 is a 24/7 fitness and health wearable that provides actionable sleep, recovery, and training insights to optimize human performance.
The next-gen 4.0 improves upon WHOOP 3.0 and prioritizes a more sleek, discreet profile that’s 33% smaller.
An upgraded sensor configuration helps capture more accurate heart rate data and new blood oxygen and skin temperature metrics. It is engineered with haptic alerts for a smart alarm that gently wakes the user at the optimal time based on their sleep needs and cycles.
The reimagined industrial design is powered by a groundbreaking battery that delivers 17% higher energy density than found in 3.0. 4.0 features a new Fast Link slider that makes it easier to swap the soft, durable SuperKnit bands developed for 4.0. The modular nature of the sensor unlocks the ability to collect data across multiple places on the body with a first-of-its-kind line of technical garments, WHOOP Body.
WHOOP implements a streamlined, portable charging block that intuitively slides over the sensor module like a backpack, allowing the strap to be charged without taking it off. 4.0 improves the on-the-go charging experience with wireless charging, achieving a thinner profile, more seamless usability, and an IP68 waterproof rating that allows it to be worn in more settings than before.
With a smaller size and new functionality via WHOOP Body, WHOOP 4.0 makes wearable technology truly wearable.
