Wakes you. Not the room.
It vibrates on your wrist at the time you set, gentle at first, then stronger. Nobody else hears a thing.

A buzz on the wrist, not a sound across the room.
Set right on the band. Nothing to pair.
The buzz starts soft and builds.
About 2 weeks per charge, depending on use.
No sound. A vibration on the wrist wakes the person wearing it.
Nobody else has to be the alarm.

The display lights up with a tap and stays dark while you sleep. One button sets the alarms and stops them.
The USB plug is built into the strap. Plug it into any USB port and you're set for the next 10 to 14 days.
Most alarms just get louder. Neatmelt moves the wake-up to the wrist.

Almost certainly. Sound is the input a sleeping brain is best at ignoring — that's why the fifth alarm works no better than the first. Hushweft delivers a physical signal directly to your wrist and escalates through three intensity levels until you respond. In our 60-night trial group, 96% of self-identified heavy sleepers reported waking on time every morning after the first week.
No. Smartwatches use small notification motors designed to get your attention while you're awake and holding a conversation. Acanthacea uses a wake-grade LRA motor tuned for the vibration threshold that reaches deep sleep. It's also the only thing the device does — which is why it runs two weeks instead of two days.
It can't. There's no speaker in it. The only person who registers the alarm is the person wearing it.
Never. You set the alarms with the buttons on the band. That's the point — most people buy this specifically so they can stop keeping a phone on the nightstand.
It's 28g on soft silicone with nothing protruding from the case. Wear it slightly loose the first few nights while you adjust. The overwhelming majority of users say they forget it's on within a week.
Three, independently. Most people run one weekday alarm, one weekend alarm, and one spare — or stack all three a few minutes apart as a built-in snooze.
