Frequently asked questions
Your Apple Watch captures the same core biometrics Whoop relies on—heart rate variability, resting heart rate, sleep stages, and activity strain. Century decodes that data with pro-level coaching so you get the clarity and motivation Whoop is known for, without buying another band.
No extra hardware required. Century fully unlocks the sensors already on your Apple Watch (or compatible wearable) so you can ditch the duplicate straps. We automatically import your daily metrics and transform them into recovery, readiness, and sleep insights tailored to you.
