How it works

One band, one button, no app. Here's the whole routine.

Your first night with Sotto.

  1. Charge it

    Unclip one end of the strap and plug the band into any USB port.

  2. Set the time

    Follow the complete English quick-start card provided the box.

  3. Add your alarms

    Pick the time and the days you want the alarms. Weekends can stay off.

  4. Wear it to bed

    At the alarm time, it vibrates on your wrist. Press the button to stop the alarm.

  5. Charge it on Sundays

    A weekly top-up means you never have to worry about the battery.

Honest about who this is for.

We'd rather you know now than after you've paid.

For you if

  • You share a room or home and wake at different times from others
  • You're a light or normal sleeper
  • You want an early alarm that doesn't wake anyone else up

Maybe not for you if

  • You regularly sleep through smoke alarms, loud clocks, and people shaking you
  • You want an alarm that's 100% guaranteed to wake anyone up. No alarm is.

Heavy sleeper? Wear it as your first alarm and keep your phone as backup. Read our heavy-sleeper page

Setup questions.

Still wondering? Ask a real person

How many alarms can I set?

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

Can I turn it off for the weekend?

Yes, you can set your alarms from Monday to Friday, and on Saturday and Sunday, our alarms will stay quiet.

Is there an app?

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

How do I charge it?

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.

How long does the battery last?

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

Can I shower in it?

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

Tomorrow morning, let them sleep.

30-day money-back guarantee. No app, no cable, no subscription.
