That page doesn't say specifically, but my recollection is that it's otherwise every 10 minutes if you're still. In non-workout mode they don't measure heart rate if you're moving; presumably not accurate enough.
All-day heart-rate monitoring can only be claimed by devices with a battery life of at least a day.
- Naritai 9y agoNeither page offered any sort of metric on what constitutes 'accurate'. so how do you know FitBit doesn't just have a lower standard than Apple does?
- dwighttk 9y agoright... I mean "continuous" on a digital device is still going to have some sample rate... Apple Watch has a 10 minute sample rate most of the time and some higher sample rate when they are doing "continuous" monitoring during a workout. Fitbit must have a great way to store that data if they really are doing "continuous" monitoring all day.
