Wake up silently through powerful wrist vibrations — even if you're the deepest sleeper in the room.
12,847 people
finally sleep well.
Phone alarms were never built
for heavy sleepers.
You set five alarms. You still wake up in a panic. Your partner already hates the sound. There has to be a better way.
Five alarms in, you're still half-asleep and racing the clock.
A blaring tone becomes background noise to a heavy sleeper.
They wake up too — and resent you a little more each morning.
Half your evening is spent dreading whether you'll oversleep.
The same device that wakes you keeps you scrolling past midnight.
Meet ONYX.

Questions people ask
before buying.
Yes. ONYX uses a calibrated dual-frequency motor that's 4× more powerful than phone haptics. We've tested it with self-described 'impossible to wake' sleepers — 96% woke up in under 30 seconds during clinical trials.
The band weighs just 22g (lighter than most rings) and uses hypoallergenic medical-grade silicone. Most users say they forget they're wearing it within minutes.
A single charge lasts 14+ days with daily alarms. A full charge takes about 90 minutes via the included USB-C cable.
You can set up to 5 independent alarms. Perfect for weekdays vs weekends, naps, workouts, or split shifts.
Zero. ONYX is 100% silent — only the wearer feels the vibration. Your partner, roommate, or dog won't hear a thing.
IPX7 rated — splash-proof, sweat-proof, and safe for showers.
Pop the core off the band and plug it into the included USB-C magnetic dock. Twice a month is all you'll need.
100-Day Wake-Up Guarantee.
If ONYX doesn't help you wake up on time, send it back. We'll refund every penny — no questions, no hoops, no charge. We're that confident it'll change your mornings.
Tomorrow morning
starts tonight.
