WHOOP requires you to buy their proprietary band and commit to 12 months. Kreev uses the Apple Watch you already own — no new hardware, no annual contract.
WHOOP benchmarks your recovery against population data. Kreev uses Z-score statistics against your own rolling history — so your score reflects how you are doing compared to your normal.
WHOOP gives you a number without showing its work. Kreev publishes its methodology and generates a plain-language AI narrative every morning explaining exactly why your score is what it is.
