Oura Ring is one of the best health tracking devices on the market. It collects your biometrics with remarkable accuracy. Longvai takes over where Oura ends — explaining what that data means, why it changed, and what you should do about it.
Oura Ring excels at hardware: always-on sensing, accurate sleep staging, comfortable to wear 24/7. Longvai excels at software intelligence: contextualizing your data, running statistical experiments, predicting readiness, and answering your questions in natural language.
If you wear an Oura Ring, Longvai makes it dramatically more valuable. Import your Oura data into Longvai and unlock the interpretation layer that Oura's app does not provide.
HRV tracking
Records HRV with excellent accuracy using infrared optical sensors
Ingests Oura HRV data, contextualizes against your 30/60/90-day baseline
Sleep stages
Detects deep, light, REM, and awake time with high accuracy
Correlates sleep architecture with next-day readiness, training, and meals
Readiness score
Proprietary algorithm combines HRV, resting HR, sleep, temperature
Transparent AI reasoning for every readiness prediction — you see why
Insight generation
General recommendations based on readiness score
Root-cause analysis grounded in your personal data patterns with Gemini AI
Experiment tracking
Limited — no statistical testing for personal interventions
Full n=1 experiment engine: Mann-Whitney U + Cohen's d + AI narrative
Data ownership
Data lives in Oura cloud; CSV export available
You import Oura data into Longvai; own and query your full dataset
Questions & answers
No conversational AI for your data
Care Chat: ask anything about your data in natural language
Doctor export
Basic data sharing
Detailed Markdown/PDF summaries with selective section sharing
Hardware
Physical ring — always-on, no charging during day, comfortable
Software — works with Oura, other wearables, or manual data entry
Illness prediction
No illness early-warning feature
Multi-metric illness early-warning from HRV + resting HR + sleep patterns
Oura tracks HRV, sleep stages, temperature, and readiness with its usual accuracy. Nothing changes on the hardware side.
Use Oura's CSV export (available in the app) or connect via the Oura API to stream data automatically.
Upload the CSV or configure the API connection. Longvai ingests your entire Oura history.
Now your Oura data has context. Baseline comparisons, root-cause analysis for readiness dips, illness early-warning, and Care Chat — all using your actual Oura metrics.
Add the AI intelligence layer to your existing wearable data.
