Product description

Clinically Validated Sleep Tracking — Without Wearing a Thing

Real-time heart rate, breathing patterns, and sleep stages — validated in clinical studies. No wearable. No camera. No subscription.

Why Parents and Sleep-Conscious Adults Choose OZI

OZI delivers the depth of top-grade wearables — without anything on your body. And unlike every other sleep tracker built for individual use only, OZI lets parents monitor their children’s sleep in real time from their phone. No camera. No wearable on the child. Guardian Mode alerts you the moment something seems off.

PREMIUM-LEVEL ACCURACY

OZI delivers 98% correlation and matches top-tier wearable sleep trackers across core sleep accuracy metrics in independent studies. It is also 45% more accurate than popular fitness bands and smartphone apps, with precision detection for exact bed entry, sleep onset, and micro-awakenings. By capturing the details many devices miss, OZI provides a more complete and dependable picture of your sleep.

The only non-wearable sleep tracker with published clinical validation data.

Fall Asleep Faster. Wake Up Feeling Human.

Soundscape

Drift off with adaptive sleep sounds — white noise, rain, ocean waves, and more — automatically turned off the moment OZI detects you’ve fallen asleep. No need to set a timer. OZI handles it.

Smart Alarm

Set a wake-up window and OZI does the rest. It monitors your sleep stages in real time and wakes you at the lightest point within that window — so you emerge from sleep naturally, not dragged out of deep sleep by a jarring alarm. Choose a 5, 10, 15, or 30-minute window. Works every night, automatically.

See What’s Happening Right Now — Get Notified When It Matters

Real-time

Unlike Withings Sleep Analyzer and most non-wearable trackers that only show data after the night ends, OZI delivers live heart rate, breathing rate, and sleep stage data throughout the night. Open the app at any time and see exactly what’s happening.

Guardian Mode

Configure exactly what triggers an alert — low heart rate, high heart rate, bed exit timeout, breathing changes — and how you receive it: push notification or email. Set monitoring windows so you only get alerted during hours that matter. Guardian Mode is designed for parents watching over children, but works for anyone who needs nighttime peace of mind.

Know How Your Child Is Sleeping — Without a Camera in Their Room

Every parent checks on their kids at night. OZI means you never have to leave the bed. Place the mat under your child’s sheet and monitor their heart rate, breathing, and sleep stages in real time from your phone. Guardian Mode alerts you instantly if something seems off — nothing wakes them, nothing touches them. Supports up to 8 devices so every child in the house is covered in a single app.

Top-Tier Accuracy. No Subscription. Total Peace of Mind.
