Why Kilvon exists
"I get up at 5. For years my alarm was my phone. Every morning the whole bedroom paid for my schedule.
So I tried waking to a vibration on my wrist, from a $30-a-month fitness band. It fixed my mornings. Nobody next to me woke up at 5 anymore. And the tap didn't hit me like the phone siren did.
The problem: I was renting a $30-a-month band for a one-button job. And the next version made the tap weaker. So I built Kilvon. One job, done quietly, bought once."
— Magnus, founder
Sound wakes the room. Touch wakes you.
A sound alarm is built to wake a room, not a person. The noise hits your partner at full volume. Your own brain has heard that ringtone a thousand times, so you snooze it. They can't.
Kilvon takes the air out of it. A vibration on your wrist reaches you through your body. Only the wearer feels it.
Nothing has to cross the room to reach you. So nothing reaches your partner either. They stay asleep three feet away.
It's an alarm, not a smartwatch. A smartwatch is a general-purpose computer that also has an alarm. It buzzes at 3 AM for a low battery, wants charging most nights, and brings a screen into the bed. Kilvon has one button and one job.
What the research actually says
97% of deep-sleep lab tries ended with the sleeper awake from a wrist vibration, most within 52 seconds (Attali et al. 2020, n=20)
100% vs 92%: a stop-start vibration woke everyone tested, a steady one didn't (Ashley 2007, n=111)
55.6% of phone-alarm mornings end with a snooze (Scientific Reports 2025, 3M+ nights)

My watch already has a silent alarm.
My watch already has a silent alarm.

Why not a $12 alarm clock?
Why not a $12 alarm clock?
