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 metrics: 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.
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 on the Sleep tab, you’ll see the full, in-depth breakdown of your sleep, color-coded by sleep stage.
Underneath the Sleep Details section on the Sleep tab, 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. Hatch Sleep Clock can easily tell the difference.
Does Hatch Sleep Clock work if two people share the bed?
Yes. When you set up your Hatch Sleep Clock, it's calibrated to only cover your half of the bed if you share one. Someone sleeping on the other side of the bed won't impact your individual data.
Does the Hatch Sleep app need to be open while I’m using it?
No. Hatch Sleep Clock can be operated from the device itself, so you can leave your phone out of the bedroom.
What’s the difference between Hatch Sleep Clock’s tracking and the sleep tracking you get from a ring or wristband?
Contactless devices like Hatch Sleep Clock work by detecting the movement and respiration rate associated with each sleep stage and then use an algorithm to infer when you’re awake, when you’re asleep, as well as each of your sleep stages.
Consumer wearable devices like rings and wristbands might infer sleep based on movement, skin conductivity, pulse rate, or other body signals. These are then used as a proxy for detecting when you’re awake, when you’re asleep, as well as each of your sleep stages.
TL;DR: you’ll get a breakdown of sleep stages from both kinds of sleep trackers.
However, aside from not requiring something to wear, Hatch Sleep Clock is different from other sleep trackers because it helps people actually improve their sleep. Once Hatch Sleep Clock has tracked your sleep for seven nights, it’ll begin to identify your unique patterns and offer small tweaks and adjustments that can help you get better rest. the algorithm identifies what will work best based on your unique sleep patterns and listening preferences.
These recommendations include audio and light options that are available right in your Hatch Sleep Clock, like specific podcasts, audiobooks, sleep music, and more.
How accurate is Hatch Sleep Clock?
Hatch Sleep Clock's sleep detection technology is independently validated in peer-reviewed research at 97% accuracy, compared to clinical polysomnography (sleep studies) at 99%.
