A couple asleep at night, each wearing an Apple Watch. An iPhone and the STOP GÜGU character sit on the nightstand.

Watching over
your sleep,
till morning.

STOP GÜGU listens for snoring and gives your Apple Watch a gentle tap — just enough to shift how you're lying.

Frequently asked questions

Do I need an Apple Watch?

Yes. STOP GÜGU works by buzzing your Apple Watch when it detects snoring, so an Apple Watch is required for the current test.

Won't the vibration wake me up?

We're tuning it to be as unobtrusive as we can. Everyone feels it a little differently, which is exactly what we hope to learn from our testers.

Is this a medical device?

No. STOP GÜGU is not a medical device, and it is not intended to diagnose or treat snoring or any related condition.

Does it cost anything?

No. STOP GÜGU is free for the whole test period.

What do I have to do as a tester?

Just answer a short survey once you've had a chance to use it.

If I apply, am I guaranteed a place?

We review each application against the places available and the devices you have, then get in touch with the people we'd like to invite.

One small thing
for tonight's sleep.
