Loud alarms spike cortisol before your eyes open.
Your brain reads a sudden loud noise as a threat.
Cortisol and adrenaline flood your system in milliseconds.
Heart rate jumps.
You wake up already in fight-or-flight — before your feet hit the floor.
That's why you feel groggy, anxious, and behind by 9 AM.
And if you share a bed, your partner gets the same spike.
Except they didn't sign up for it.
Onyx is a silent vibration alarm worn on your wrist.
No sound.
Only the person wearing it wakes up.
99% wake on time.
You start the day calm.
They keep sleeping.
If it doesn't wake you up — for any reason — you have 100 days to send it back.
That's the Wake-Up Guarantee.
