The Story
Simple. Disposable. Clinical Accuracy from the Comfort of Your Bed.
Forget the wires, the uncomfortable headgear, and the confusing instructions. Heartstrong Sleep brings you the NightOwl®, the world’s smallest and most convenient home sleep apnea test.
Designed for simplicity without sacrificing accuracy, this fingertip-sized sensor uses advanced PAT (Peripheral Arterial Tonometry) technology to monitor your sleep health over multiple nights—giving us a complete picture of your rest without interrupting it.
Why Choose the NightOwl?
-
Zero Stress: No bulky equipment. Just a tiny sensor taped to your fingertip.
-
Multi-Night Data: We record up to 3 nights of data to ensure we don't miss a thing (because one bad night shouldn't define your diagnosis).
-
Completely Disposable: When you're done, simply discard it. No return shipping, no cleaning, no hassle.
-
Instant Analysis: Your sleep data is securely uploaded to the cloud the moment you wake up, allowing our board-certified physicians to interpret your results faster.
What The Device Measures
Despite its size, the NightOwl is a powerhouse, tracking critical biomarkers to detect Obstructive Sleep Apnea (OSA):
-
Blood Oxygen Levels (SpO2)
-
Heart Rate (Pulse)
-
Body Movement (Actigraphy)
-
Peripheral Arterial Tone (PAT)
How It Works
-
Order: We ship the NightOwl directly to your door.
-
Sleep: Download the app, tape the device to your finger, and sleep as usual.
-
Results: Results are captured and uploaded to the cloud for physician review.
- Done: Once data is confirmed and reviewed by physician, you can dispose of the device.
The path to perfect sleep starts with a home sleep test!
