Is Oura Ring or WHOOP better for sleep tracking?
Both are among the best sleep trackers available and significantly more accurate than Apple Watch or Fitbit for sleep staging. In independent studies (comparing to clinical polysomnography), Oura and WHOOP perform similarly for detecting sleep stages (light, REM, deep), though both have accuracy limitations. Oura Ring Gen 4 improvements in sensor accuracy have been validated. Key differences: Oura's temperature deviation tracking is valuable for detecting illness onset or menstrual cycle phase shifts (temperature rises after ovulation). WHOOP's Sleep Coach proactively tells you what time to go to sleep to hit your sleep debt goal — actionable guidance Oura doesn't provide in the same way. For women who want cycle tracking: Oura. For training-focused recovery: WHOOP.
Year 1: Oura Ring Gen 4 ($349) + $5.99/month × 12 = $420. WHOOP with annual plan: $239/year (no hardware cost). WHOOP is cheaper in Year 1. Year 2+: Oura $72/year ($5.99/month). WHOOP $239/year. Oura is dramatically cheaper starting in Year 2 — about $167/year less. 3-year total: Oura ~$564 vs WHOOP ~$717. Oura wins on lifetime cost if you keep either device over 2+ years. However, WHOOP upgrades your hardware for free as new versions release — your $239/year includes the latest WHOOP hardware. Oura charges full price for new ring generations. For frequent upgraders, WHOOP's model is more cost-effective long-term.
