Oura requires a $299 ring before you can access a single metric. Kreev works with the Apple Watch already on your wrist. Start for free — no upfront hardware cost, ever.
Oura's Readiness Score benchmarks you against population data. Kreev uses Z-score statistics against your own rolling baseline — so a night of 7.8 hours is evaluated against your typical sleep, not a global average.
Oura gives you a readiness score and brief tips. Kreev generates a full plain-language AI narrative every morning — explaining each metric's contribution to your score and how it compares to your baseline.
