The Access Gap
Most people with sleep apnea haven't been diagnosed yet.
About 80% of people with obstructive sleep apnea haven't been diagnosed. Getting each patient tested takes devices, shipping, follow-up and scoring, and that work adds up for a busy clinic. Wesper takes it on so more patients can be tested.

What is Wesper?
Wesper develops FDA-cleared home sleep testing medical devices. Our ecosystem brings together two wearable tests, Wesper Lab and Wesper Lite, a clinical portal, and a managed service for dropship, patient support and optional interpretation.
How does Wesper compare with in-lab polysomnography?
Wesper devices show 95%+ AHI correlation to in-lab polysomnography (PSG), with narrow limits of agreement (Sleep Medicine 2025; JCSM 2023).
What is the difference between Wesper Lab and Wesper Lite?
Wesper Lab uses two patches on the chest and abdomen to capture direct respiratory data, including an FDA-cleared airflow signal without a nasal cannula. Wesper Lite is a PPG-based sleep test in a ring format that is easy to deploy and easy for patients to use.
Does Wesper Lab need a nasal cannula?
No. Wesper Lab measures an FDA-cleared airflow signal from its two wearable patches, so patients sleep without a nasal cannula.
Can patients test for more than one night?
Yes. Multi-night testing comes standard with Wesper, and repeat studies stay on the same patient record for longitudinal follow-up.
Is Wesper secure and HIPAA compliant?
Yes. Wesper is HIPAA compliant and holds SOC 2 Type 2.
Who can use Wesper home sleep tests?
Wesper home sleep tests are ordered by healthcare providers for their patients. Patients complete the sleep test at home. Wesper home sleep tests are indicated for adult use only.
