Hatch Sleep Clock reads your breathing and micro-movements using a motion sensor. It works through bedding and blankets and from 2-4 feet away.
When you first set up Hatch Sleep Clock, it’ll calibrate to your breathing and movement patterns over the course of seven nights. Beyond the first seven nights, your device will continue to learn your unique rhythms, getting even more precise by the day.
Does Hatch Sleep Clock track sleep stages?
Yes. Hatch Sleep Clock uses your breathing and movement patterns to measure four key things: breathing rate, movement, whether you're in bed or not, and total sleep time.
These four data points are what Hatch Sleep Clock’s algorithm uses to derive your sleep stages.
You can see your sleep stages and overnight insights in the Sleep tab of the Hatch Sleep app. An arc visual represents your total sleep, as well as the time you got in bed and the time you got out of bed:
As you continue to use Hatch Sleep Clock, it will also begin to determine your sleep efficiency and night-to-night consistency.
If you select Sleep Details beneath the arc, you’ll see the full, in-depth breakdown of your sleep, color-coded by sleep stage.
Underneath the Sleep Details section, you’ll see a river view that outlines your last seven nights of sleep. This feature allows you to easily view your consistency in regards to bed time, rise time, and your total sleep time.
How does Hatch Sleep Clock know I’m asleep if I’m not wearing anything?
Motion sensors work well for tracking sleep, and that’s because your body moves and breathes differently in each sleep stage. For example, deep sleep is typically very still, REM involves more subtle movement, and light sleep falls somewhere between the two. Hatch Sleep Clock can pick up these minute differences between sleep stages that are normally invisible to the naked eye.
TL;DR, your breathing is very different when you’re awake versus when you’re asleep, as well as when you’re moving through different sleep stages. Using the latest in sleep tracking technology, Hatch Sleep Clock can easily tell the difference.
