that’s our intention in depending on the Active Minutes metric as opposed to
a 10k benchmark. Making sure you’re being properly “rewarded” for sustained
physical activity rather than a blanket number of steps taken. Many trackers
(and wrist-based devices) are reported to overestimate steps - which is why
we aim to meet the accuracy of foot pods. (Murmurings of that indicated
.)
Why does my Heart Rate data differ between Motiv Ring and (Polar, Apple
Watch 3, etc)?
●
Motiv will only report average measurements per minute, so if the max
HR is not sustained over a span of a minute or so, the minute average
for that time will be lower than what other trackers can report, as they
can report HR with higher temporal resolution.
●
There is a trade-off between higher temporal resolution and battery life.
So if we were to report HR more frequently, our battery life would drop,
and we decided that battery life is more important for your ring, as it is
a 24/7 monitor, and not fitness-training focused.
●
Wrist-worn devices often have a much stronger optical signal to work
with, and have a lot less ambient interference because the optical
sensor is more protected under a larger area. So our algorithms have to
be even more robust than what is run on wrist-worn trackers. Given the
constraints of available chips for our form factor, our limited real-estate,
and our desired battery life, that is a serious challenge.
4. Steps While Driving?
The vibrations of the car/bus on the road or those of the trian on the rail line
may sometimes transfer to your hand and look like steps to the ring.
Especially when your ring-wearing hand is resting on the door, window or the
