The Hatch Sleep Clock tracks your sleep without a ring, a watch or a mat under the sheets. It sits on your nightstand and uses low-power radio pulses to read your breathing. This Hatch Sleep Clock review covers what the $249.99 device does well, where its tracking falls short, and who should buy it.
Wired reviewed the clock on 20 October 2026, about two months after it went on sale. By then Forbes, Tom’s Guide and others had lived with it too, so there’s enough testing to judge it fairly.
Key takeaways
- The Hatch Sleep Clock costs $249.99 and went on sale in August 2026, after Hatch first announced it in June.
- It has no camera, no microphone and nothing to charge. It senses chest movement from a few feet away.
- Hatch says the sensing tech is 97% accurate at detecting sleep compared with a clinical sleep study. That is the company’s figure, not one reviewers measured.
- You don’t need a subscription to see your sleep data. Hatch+ only adds to the sound library.
- Reviewers agree it works best for one person sleeping alone. Partners and pets can blur the data.
How does the Hatch Sleep Clock track sleep without touching you?
Think of a bat’s sonar, only much weaker and using radio. The clock sends out pulses that Hatch says use a fraction of the energy of a Wi-Fi router. The pulses bounce back, and the clock reads the small rise and fall of your chest.
From that signal, Hatch says the clock works out your breathing rate, movement and restlessness, and whether you’re in bed at all. It then estimates when you fell asleep and how you moved through light, deep and REM sleep. REM (rapid eye movement) is the stage linked to vivid dreams.
Independent reviewers suggest placing it at about mattress height, around 2 to 4 feet from you. It also learns your patterns over the first few nights, so the first week of data will be rough.
What does it do besides tracking?
A lot, and that’s the point. It’s a sunrise alarm, a sound machine and a wind-down coach. You pick a wind-down time, and the clock slowly adds soft light and ambient sound. In the morning it brightens gradually to mimic sunrise.
You won’t get a nightly sleep score. Instead, as Mugglehead reported at launch, it looks at trends and suggests changes, such as moving your bedtime, getting morning sunlight or cutting screen time. Hatch says these tips draw on CBT-I, the talking therapy for insomnia (cognitive behavioural therapy for insomnia). The controls are on the clock itself, so your phone can stay out of the bedroom, a habit that ties into the wider debate about screen time.
Is the Hatch Sleep Clock accurate?
It’s accurate enough to show trends, but don’t read too much into a single night. Hatch cites a third-party study that puts sleep detection at 97%, compared with 99% for polysomnography, the hospital sleep test with wires on your head. Note the fine print: that 97% is for spotting sleep versus wake, not for sorting sleep into stages.
Real bedrooms are messier than a lab. In its review on 28 August 2026, Forbes saw total sleep time differ from an Oura Ring by an hour or more on a few nights each week. Apartment Therapy’s tester found the clock sometimes logged a husband or a dog getting in and out of bed as tossing and turning.
Hatch’s own help pages admit pets near the bed can skew the data. The clock tracks whoever sleeps closest to it, so a partner who drifts toward your side can end up in your results.
How does it compare with other sleep trackers?
| Device | How it tracks | Price | Best for |
|---|---|---|---|
| Hatch Sleep Clock | Radar on the nightstand | $249.99 | Solo sleepers who hate wearables |
| Hatch Restore 3 | No tracking | $169.99 | Sunrise light and sound only |
| Withings Sleep mat | Pad under the mattress | $199.99 | Hidden tracking with no bedside gadget |
| Google Nest Hub (2nd gen) | Radar plus screen and mics | Varies | People already using Google’s smart home |
| Oura Ring 5 | Worn on a finger | Ring plus paid membership | Couples and data-heavy users |
The Nest Hub is the closest rival. It adds microphones that can pick up snoring and coughing, plus a screen and a voice assistant. Hatch’s clock has none of those, which is less capable but more private.
Do you need a Hatch+ subscription?
Not for tracking. Your sleep data and insights come free. You get a 30-day trial of Hatch+, and after that the full library of more than 2,500 sounds, stories and meditations costs $5.99 a month or $59.99 a year, according to Mugglehead. The clock still needs the Hatch app and its cloud service to work.
Hatch offers a 30-night trial and a one-year warranty. My take: a one-year warranty feels short for a $250 bedside gadget you could keep for five.
Who should buy it, and who should skip it?
Buy it if you sleep alone, you can’t stand wearing a ring or a watch in bed, and you want a sunrise alarm anyway. In that case the tracking is a cheap upgrade, since the Restore 3 costs only $80 less and tracks nothing.
Skip it if you share the bed with a restless partner or a dog, if you want precise sleep-stage data, or if you already own a good wearable. You’d be paying for numbers you already have.
What happens next
At launch the clock was sold only on hatch.co, with Amazon and other retailers expected to stock it later in 2026. Wider sales usually bring discounts. Because the clock improves through software, its sleep-stage estimates could get better with app updates, so later reviews may land differently.
The bigger trend is clear. Radar sleep sensing used to be a niche Google experiment. Now it’s showing up in alarm clocks, and more makers will likely follow.
FAQ
Does the Hatch Sleep Clock have a camera or microphone?
No. Hatch says it uses only a low-power radio motion sensor that reads breathing and movement. It has no camera and no microphone.
Can the Hatch Sleep Clock track two people?
Not reliably. It’s built for one sleeper and tracks whoever is closest. Partners and pets moving nearby can affect the results.
Is a subscription required to see sleep data?
No. Sleep tracking and insights are included. Hatch+ ($5.99 a month or $59.99 a year after a 30-day trial) only unlocks the full audio library.
If you sleep alone and hate wearables, start with Hatch’s 30-night trial: give it a week to calibrate, then compare its trends with how rested you actually feel.
