Valerie is right - WhoopStrap 3.0 is good - interesting new features - Bluetooth BLE, 5-day battery, heart rate broadcast (can be picked up by certain treadmills, rowers, bikes, etc). There is also a new live coach feature, which may be attractive to some. At the team level, there is more raw data and additional analytics available to coaches. Individual users still cannot access/own their own data. Still no love for n-of-1 individual scientists. In Whoop’s defense, they claim the volume of multiple-measurements-per-second data is prohibitively complex and “large” - though I suspect some in this community have resources and interest to address the challenge.
