Oura shows the tag. Corio shows the nights. You tag your nights — late meal, workout, magnesium, hot room. Oura keeps the list and analyzes almost none of it: custom and repeating tags never get a Discovery. Corio takes every tag, including those, and shows the nights behind it against your own baseline — so you know what moved your HRV and sleep, and what didn't. Oura says what. Corio says why. WHAT THE DEVELOPER'S OWN 298 NIGHTS SHOWED Real numbers from one Oura Ring, computed the same way Corio does it for you — each tag's nights against your own 7-night baseline. No averages from other people. • Late bedtime → sleep score 84 → 76. Every hour later cost about 5 points and 40 minutes of sleep. • Late bedtime → HRV: 0%. Same nights, HRV didn't move (31.3 vs 31.7). The drop was sleep duration, not recovery. The score can't tell you that — the tags can. • One warm night, no AC → HRV 49 → 29, resting heart rate 53 → 59, on a night with 8.7 h of sleep and a sleep score of 91. The score looked fine. The body didn't. HOW IT WORKS 1. Connect — sign in with Oura. Corio pulls your nights and the tags you already log in the Oura app. They keep arriving even when Corio is closed. 2. Tag as usual — in Oura or in Corio. Late meal, caffeine, workout, travel, illness — anything. Late meals, workouts and late bedtimes are tagged for you automatically. 3. Get the receipt — every morning: what changed, by how much, and the exact nights that prove it. A preliminary read after 3 nights, the full receipt at 5. Share it if you like.

Corio calculates your physiological age by analyzing your Oura Ring data, such as readiness, HRV, resting heart rate, and sleep. It presents this as a single number, indicating whether your body is functioning younger or older than your chronological age. ### How does Corio use my Oura Ring data? Corio connects directly to your Oura Ring data, automatically importing readiness, sleep stages, HRV, resting heart rate, SpO2, and temperature. It uses this information to provide detailed insights without manual entry. ### Can Corio track my recovery hour by hour? Yes, Corio offers hour-by-hour recovery tracking by monitoring HRV throughout the night. It also provides a full sleep hypnogram detailing REM, deep, and light sleep phases, and a live scale for stress and recovery. ### How does Corio help me understand my daily habits? Corio displays your meals, workouts, and heart rate on a single timeline, allowing you to see the direct impact of activities like late dinners or intense workouts on your sleep and recovery. ### Does Corio offer personalized insights? Yes, Corio builds correlations based on your unique data, not general population averages. This means it identifies what specifically raises your HRV, rather than relying on generic recommendations. ### Can I compare my recovery with friends using Corio?
