About Wesper

Wesper was founded by Amir Reuveny and Adi Mordechai. It is a health technology company focused on simplifying how sleep disorders are identified and monitored without relying on traditional in-lab studies.

The brand’s core offering is an FDA-cleared at-home sleep testing platform designed to deliver high-resolution physiological data. The system captures signals such as respiratory effort, airflow, and sleep staging, providing a more detailed view of sleep patterns in a home setting. The platform also gives access to booking demos through its website.

Core Offering

1. Home Sleep Testing (HSAT)

   Home Sleep Testing (HSAT) evaluates sleep disorders such as obstructive sleep apnea by collecting physiological data during your normal sleep routine. The system uses wearable, wireless patch-based sensors that you apply before sleep and remove after waking, allowing data collection in a non-clinical environment.

   The system delivers Level 3 HSAT data, including measurements such as thoracic and abdominal respiratory effort, airflow, blood oxygen saturation (SpO2), heart rate, and body position. It also tracks snoring, respiratory rate, movement, and skin temperature, along with advanced metrics like sleep staging and hypoxic burden. These parameters are used to identify breathing interruptions and oxygen fluctuations that may be associated with sleep apnea and related concerns.

   Data is collected continuously throughout the night and analyzed using automated algorithms to detect respiratory events and sleep stages. The platform provides access to both raw data and interpreted results, which may support clinical review.

   According to the brand, the technology has been evaluated against polysomnography, with reported correlation in measures such as the apnea-hypopnea index (AHI). The service also includes guided setup, real-time updates, and access to support, which may help ensure proper use during testing.

Wesper Advantages

   The brand also claims to integrate operational and clinical workflow support through a unified service model. It combines hardware, software, guided onboarding, remote monitoring support, and provider-connected reporting into a single ecosystem.

Wesper Limitation

1. Dependence on Proprietary Algorithms

   Wesper relies heavily on automated scoring systems. Sleep apnea scoring, oxygen desaturation detection, central apnea classification, airflow estimation, and total sleep time analysis depend on internally developed AI-assisted processing models and software logic. As many of these outputs are generated through derived calculations rather than direct measurement alone, the accuracy and interpretation of results depend significantly on the company’s internal signal-processing methods and modeling decisions.

   The official site also provides limited technical transparency into how these systems operate in routine use. It does not publicly provide detailed documentation covering algorithm architecture, model version history, preprocessing standards, event-classification methodology, or software-update governance. It is difficult to inspect or validate how signal interpretation changes over time as software systems evolve. You may want more transparency if you prefer systems where core measurements come from simpler, directly interpretable channels and publicly documented scoring logic.

Wesper Alternatives
