Detailed Frequently Asked Questions
Everything you need to know about OZI in one place.
What exactly is OZI Sleep?
OZI Sleep is a contactless, under-sheet sleep tracker. It slides beneath your bottom sheet and measures heart rate, breathing, movement and sleep stages — no wearable, camera, or microphone.
How is OZI different from a smartwatch or ring?
Nothing to wear or charge. OZI senses through pressure and vibration from under the sheet, so there's no skin contact, no nightly charging, and no screen light to disrupt your sleep.
Do I need to turn it on every night?
No. OZI stays under your sheet and starts tracking automatically when you get into bed.
Is OZI a medical device?
OZI is a wellness product, not a certified medical device. It gives medical-grade insights to help you understand your sleep, not to diagnose conditions.
