WHOOP
Screenless wrist strap tracking strain, recovery and sleep
No display at all. This subscription wearable is built around a daily strain and recovery score, derived from heart rate variability, resting heart rate and sleep, and it appeals to people who train hard and want a number telling them to back off. Like all wearables it is better at trends than at absolutes, and it is a recurring cost rather than a one-off purchase.
