This is the best sleep watch I’ve ever used, finally something that gets me up without making me hate my life at 6am. Comfortable enough that I forget I have it on too.

If you wake up to a phone alarm, and your partner does too, yes. Onyx vibrates on your wrist instead of blasting the room. You wake on time, they don't. Athletes use it for early travel days, parents use it for shift work, anyone with light-sleeping roommates uses it instead of headphones under the pillow.
One purchase, no subscription, no app required. Smartwatches with the same feature run $250+ and need a phone tether to work. Onyx is a single-purpose tool that does one thing perfectly, and lasts on a single charge for nights at a time.
- Deep sleepers who don’t respond to traditional sound alarms
- People who frequently oversleep or unconsciously hit snooze
- Couples who want to wake up without disturbing their partner
- Individuals with ADHD who find mornings especially difficult
- People with narcolepsy who benefit from a dependable vibration alert
- Hearing-impaired sleepers who need a silent and reliable way to wake up
- How long does the battery last? Up to 14 days on a single charge with normal nightly use.
- Is it loud enough to wake me? The vibration is calibrated to wake you without sound. Heavy sleepers can set repeat vibration intervals.
- Does it need a phone or app? No. Onyx is a standalone device, set the alarm directly on the band.
- Can I shower with it? It's water-resistant for daily use but not designed for swimming or showering.
This is the best sleep watch I’ve ever used, finally something that gets me up without making me hate my life at 6am. Comfortable enough that I forget I have it on too.

First-Try Wake-Ups
Five escalating vibration patterns get you out of bed before your half-asleep brain can talk you back into it. Most users hit their actual alarm time within the first week.
100,000+ Already Stopped Snoozing

Put It On. Go to Sleep.
There's no app to download or Bluetooth to pair. Buckle the band on at night, set the time on the display, and that's it, the alarm runs silently and stops when you press the button on the wrist.
Why Snoozers Won't Shut Up About This Alarm
The Snooze Button Doesn't Exist Here
The phone alarm gives your half-asleep brain a button it can hit before you can think properly. Onyx Sleep doesn't. The vibration runs until you sit up, locate the button on the band, and press it on purpose, and by then your body has already done the work of waking up.
Only wakes you up (not partner/kids)
Sound wakes the whole room. The vibration wakes only you, strong enough to register, quiet enough that your partner sleeps through it. The "Sorry" stops, and the guilt about somebody else's tired morning goes with them.
Built for your 'snoozing' brain.
Smart alarms try to outthink your sleep cycle. Sleep apps want data, logs, and trust in the algorithm. Onyx Sleep isn't trying to be clever, it runs the alarm at the time you set, every morning, escalating until you're awake.
One System, Zero Maintenance
Other no-snooze methods need maintenance, apps want check-ins, accountability texts need a second person who eventually gets tired of being your alarm, the "phone in the bathroom" rule requires discipline you don't have at 6:01am anyway. Onyx Sleep needs none of that. Buckle it on before bed and that's the entire system.
Designed for Sensitive Sleepers
Soft silicone band, hypoallergenic, comfortable for side sleepers and anyone who's particular about wearing things to bed.
Built for the Brain You Actually Have
Five-pattern escalation defeats sound habituation, snooze reflexes, and the half-asleep willpower negotiation that talks you back into bed every other morning.
Trusted by 100,000+ Snoozers
From night-shift nurses to students with 8am classes, Onyx Sleep is the wake-up tool used by people who'd given up on ever waking up the first time.
It’s Not You. It’s the Tool.
Phones, smartwatches, sunrise lamps — none of them were built to wake a snoozer. 100,000+ people stopped fighting their alarm and switched to something that worked for them.
I bought this because I have to wake up at 5am to go to work and my missus always has a go at me because she wakes up from my alarm, problem solved now! 🙏 First couple mornings she didn't even realise I was up until I came back to bed with coffee. Honestly should've bought one years ago.
This little thing! Soooo much better than a LOUD ASS sound in the morning that instsntly gets my heart racing, I love it! Now I actually wake up feeling calm instead of like the building is on fire and I have 30 seconds to evacuate. 10/10 would recommend.
Wow, Just wow. would never thought this product would save my marriage haha! Wife was about half a step from sleeping in the spare room because of my snoozing through six alarms every morning. We're back to actually liking each other in the AM.
Works amazing! Got me up on the first vibration the very first morning. Never going back to a phone alarm.
Love the packaging! looks like an apple product, also it works amazing! No cortisol spikes in the morning looll my mornings actually feel calm now and I'm not starting the day already stressed and behind. Big difference for someone who used to dread the alarm.
This is the best sleep watch I've ever used, finally something that gets me up without making me hate my life at 6am. Comfortable enough that I forget I have it on too.
The quality is unreal, feels premium and looks even better in person. Honestly didn't expect it to feel this good for the price, looks like something twice as expensive on my wrist. Battery has lasted way longer than I thought too.
Great product and customer service was amazing, had a quick question about the charging cable when mine arrived and they got back to me the same day with a clear answer. Nice to actually deal with a real person for once.
Frequently Asked Questions
You've got questions. 100,000+ Onyx Sleep users had the same ones.
Yes, and the reason is the part nobody else does well: there's no snooze button. Five escalating vibration patterns run until you sit up and press the stop button on the band deliberately. By that point your brain is online. Of the 100,000+ chronic snoozers who've made the switch, 97% report waking up on the first try within the first week.
No. The alarm is silent, only the vibration, and only on your wrist. Most partners report not knowing their significant other is up. If your partner is a particularly light sleeper or you sleep with your wrist pressed against them, the faint mechanical hum may register, but no Onyx Sleep user we've heard from has reported the alarm waking their partner.
A phone alarm has a snooze button your half-asleep brain can hit before you're conscious. Smart alarm apps wait for a "light sleep" window, useful in theory, but they often trigger early or wait too long when you've slept badly. Onyx Sleep runs at the exact time you set, with no snooze and no algorithm to outsmart.
The adjustable strap fits wrists from 5.5" to 9" (14cm to 23cm), which covers about 99% of adults. If yours falls outside that range, contact support, we have an extended-strap option that fits up to 11" wrists. The band is soft silicone and sits flush whether you sleep on your side, your back, or your stomach.
The band is the same soft silicone used in continuous glucose monitors and recovery wearables, designed specifically for overnight wear. Most users say they forget they have it on within the first 20 minutes. If you wear a watch to bed, the experience is essentially identical except quieter and lighter.
The battery lasts 7 days on a full charge. It charges in 90 minutes via a magnetic cable that ships with the device. Most users plug it in once a week, usually during their morning routine, and that's the extent of the maintenance.
No catch, we manufacture in volume and sell direct, which cuts out the retail markup most sleep gadgets get pushed through. The 100-day money-back guarantee exists so you can verify that for yourself. Most of our cost goes into the silicone band, the haptic motor, and the firmware that runs the five-pattern escalation. None of it goes to retail margin.
100 days, full refund, return shipping covered by us. Use it every night for at least three weeks. If by week three you're still snoozing or the alarm isn't waking you up, send it back through the prepaid return label and we'll refund every cent. We don't ask why and we don't try to talk you out of it.
