The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
they would use an algorithm firstbeat had an algorithm and I'm sure heart math has its own algorithm and they're both proprietary to impute from that whether they believed that the user was in a more parasympathetic or sympathetic state or under a period of profound stress like exercise

when I got really into this there were basically two companies that were doing the analysis heart math and first beat I chose to work with first beat even though I would say at the time both of their algorithms were excellent but the first beat was a you actually that it came with its own like little EKG thing
