Questions, answered honestly.

Yes. It physically vibrates firmly on your wrist, like a phone buzzing in your hand.

Honestly, it depends: Most heavy sleepers find the vibration enough. While others don't, if you, in the past have slept through things like blaring smoke alarms, 5-10 phone alarms and more, then to be honest, no.

It's designed not to: there's no ringing, just a vibration on your wrist. The motor hums faintly, while still waking you up.

Create up to 10. Each on its own custom schedule.

Yes. You can set your alarms for Monday to Friday, and on Saturday and Sunday, our alarms stay quiet.

No app, no Bluetooth, no account, and no subscription. Everything is set on the band itself.

Yes, an alarm is an alarm. We built it for mornings, but it's your band.

The USB plug is built into the band; unclip the strap and plug it into any USB port. There's no cable in the box.

Up to 30 days per charge, depending on how many alarms you use. The easiest habit is a quick charge every Sunday.

It weighs 17 grams, about the same as three sheets of printer paper, on a soft silicone strap.

The band is one piece with a metal buckle, so there's no insert to pop out. It fits wrists from 130 to 235mm.

No, take it off to shower or swim. We don't claim it's waterproof.

It's one of our favorite uses: for a partner who sleeps through alarms, or a son or daughter heading to college. The 30-day guarantee still applies.

Couples with different wake times each wear one. The price per band drops when you buy two or three.

Yes, we designed Sotto for all ages. 

About 8–12 days. We'd rather tell you that than promise two days and miss.

No. It's an alarm, and it doesn't diagnose, treat or improve any condition.

It's worth mentioning to a doctor if you regularly sleep through alarms. Sometimes there's a fixable reason that no alarm can solve.
