Brian C.
US Navy veteran with service-connected sleep apnea. CPAP user since 2023. I built CPAP Clarity because I wanted to understand my own therapy data without installing desktop software or trusting a cloud service with my health information.
Every article on this site is written from the perspective of someone who actually uses CPAP every night. I cross-check clinical claims against published research (AASM guidelines, peer-reviewed studies) and verify every data feature against OSCAR and manufacturer apps before it ships.
CPAP Clarity is free, private, and funded by affiliate links and community support. Your sleep data never leaves your browser.
