Apple Watch will add support for native sleep tracking with watchOS 7, tying it along with new options like Wind Down on iPhone and iOS 14. In new interviews following WWDC, Apple VP of applied sciences Kevin Lynch provided extra particulars on the technique behind the corporate’s implementation of sleep monitoring with Apple Watch.
Chatting with the Independent, Lynch defined that Apple spent “lots of time studying concerning the science of sleep” earlier than including sleep monitoring to Apple Watch.

Lynch explains that the main focus, “Is admittedly about getting sufficient sleep and the principle factor about that’s the problem of going to mattress. There are such a lot of issues on the earth to distract us and occupy our consideration. Supporting folks in managing that transition is the place the magic is.”
One of many differentiators between Apple Watch’s native sleep monitoring app and third-party apps is the quantity of knowledge offered to customers. Many third-party apps provide particulars on issues like deep sleep and sleep phases, however Apple’s app forgoes that technique:
“In our testing, what we’ve discovered is that it’s very obscure what’s happening in your mind from a tool that’s not studying {the electrical} indicators of your mind,” Lynch explains. “In any of those adventures we go on when constructing issues right here we ask, what is going to take advantage of distinction for those who, from a mainstream perspective, might be simple, useful and empowering.”
In a separate interview with CNET, Lynch elaborated a bit extra on the testing Apple did earlier than concluding that the period is a very powerful sleep information level to trace:
“Even in our research, we had folks put on EEGs on their heads, so we acquired perception into {the electrical} exercise of their mind, along with what we’re capable of sense on the wrist with Apple Watch,” Lynch says. “And we’ve realized quite a bit about how the principle factor right here is admittedly about period.”
Lynch additionally stated that Apple needs to keep away from inflicting folks nervousness concerning the quantity of sleep they get however relatively offering recognition when the targets are achieved:
“There may very well be nervousness that individuals have about going to sleep, and that nervousness itself can truly trigger extra issues when it comes to going to sleep,” Lynch says. “Many individuals are already effectively conscious that they haven’t been getting sufficient sleep, and so we’re not including to that, however we’re positively acknowledging when you might have achieved your targets.”
And naturally, Lynch emphasised that privateness is on the forefront of Apple’s implementation of sleep monitoring — in contrast to a few of the competitors.
Corporations like Fitbit have used anonymized consumer information for years to check demographic sleep patterns and enhance observations on sleep, however Apple doesn’t plan to do this. As a substitute, Apple has been constructing its machine studying fashions from information collected via inner research.
“And that takes a very long time. So we’ve been engaged on this for some time,” Lynch says. “We deal with the information that’s being collected on a consumer’s system with a excessive degree of sensitivity round privateness. … Apple isn’t seeing your sleep information.”
