Sanso - Your Apple Watch tracks SpO2 nightly. Now you can see it.

For 10 years, I woke up exhausted every morning. I told myself it was stress, or just getting older. Then I found my Apple Watch blood oxygen data — buried deep in a menu I'd never opened. My SpO2 had been dropping every single night. Turned out I had sleep apnea. After treatment, the exhaustion vanished overnight. Ten years. The data was there — I just couldn't see it. Sanso surfaces your Apple Watch SpO2 data every morning with a plain-language AI explanation. No digging through menus.
