About Sanso: Blood Oxygen SpO2 Log
Your Apple Watch has been measuring your blood oxygen (SpO2) every night. Most people never look at it. Sanso makes that data visible — automatically, every morning. --- What Sanso does --- Daily SpO2 Report Each morning, receive a summary of your previous night's blood oxygen levels — rated Normal, Check, or Alert. No manual tracking. Just wear your Watch. SpO2 Graph See how your blood oxygen changed throughout the night, hour by hour. Spot patterns you'd never notice from a single number. AI Insights Sanso sends your SpO2 stats to an AI and returns a plain-language explanation of what you're seeing. No medical background needed to understand your own data. SpO2 History Browse past reports by date. The longer you use Sanso, the clearer your personal baseline becomes. --- How it works --- Sanso reads SpO2 data already stored in Apple Health by your Apple Watch. No new device needed. No pairing required. Just install and your data is ready. Compatible with Apple Watch Series 6 and later (SpO2 sensor required). Apple Watch SE (1st and 2nd generation) is not supported. --- Important --- Sanso is a wellness app, not a medical device. It is not intended to diagnose, treat, or screen for any medical condition. If you notice concerning patterns in your data, please consult a healthcare professional. AI Insights use Anthropic's Claude API to explain your SpO2 statistics. No raw health data or personally identifiable information is transmitted. Your explicit consent is required before any data is sent. See our Privacy Policy for details. --- Requirements --- - iPhone with iOS 17 or later - Apple Health access - Apple Watch Series 6 or later (recommended for SpO2 data) --- Support --- Questions or feedback: [email protected] --- Legal --- Terms of Use: https://sanso-tariteru.vercel.app/terms Privacy Policy: https://sanso-tariteru.vercel.app/privacy
What’s new
Version 1.3 · Updated August 7, 2026
We rebuilt the report screen. - Days now stack in a scrollable timeline instead of swiping one day at a time - Every card shows that day's chart, with your sleep hours shaded behind it - The History tab is now part of Reports Notifications changed too. - No more fixed daily reminder. You only hear from us on days your oxygen dipped - If it goes below 90%, you get a heads-up right away - You can pick what time the daily summary arrives Also - Stats reordered to Status / Alert / Check / Lowest SpO2, each with its threshold - Fixed a bug where the streak counter reset in the morning
