- matco11 11y agoYou are right. A few months ago Jawbone UP3 definitely had HRV listed in the heart health features. That's specifically why I was looking to buy it. I guess that's close to impossible with an optical sensor.
- andrewjshults 11y agoEven the standalone optical HRMs (e.g., Scosche RHYTHM+) aren't good enough to do HRV[1] even though their accuracy compares favorably with the chest strap models[2] [1] http://www.dcrainmaker.com/2014/05/scosche-antbluetooth-optical.html http://www.dcrainmaker.com/2014/05/scosche-antbluetooth-opti... about 10% down the page [2] http://www.dcrainmaker.com/2014/05/scosche-antbluetooth-optical.html#optical-hr-accuracy-geekfest http://www.dcrainmaker.com/2014/05/scosche-antbluetooth-opti...
