The Morpheus chest strap provides the best data for HRV and workout tracking compared to armband devices.

“at the end of the day I said look the chest STP is giving us the best dat much it's unambiguous If people really want to wear an arm Bice device because they just don't want to put the chest rep on we work with the Rhythm the goost Rhythm 24 it uses the exact same sensor that Morpheus uh used in our original armband that you have and so if they want to do that they can they can measure that way but from a accuracy perspective from both the HRV and the workout it just made sense for us to standardize that use the chest strap and make it as as universal as possible rather than trying and sell two devices which people were ultimately somewhat unsure of”
