Frequently asked questions

Is Oura Ring 4 worth $349?

Yes if you want passive sleep tracking + women's health features + 7-day battery. Skip it if you don't want the $5.99/mo subscription — the hardware works without it but the meaningful insights live behind the gate.

Do I need the Oura subscription?

Yes for full features. Basic sleep + activity work without it. Cycle Insights, Readiness Score history, and Rest Mode need the subscription. Yearly cost: $71.88.

Oura Ring 4 vs Whoop 5 — which is better?

Whoop wins for athletes wanting recovery science and 24/7 strain tracking. Oura wins for passive daily use + women's health + no-band comfort. Oura is cheaper long-term ($299 + $71.88/yr vs Whoop $239 + $360/yr).

Where's the cheapest place to buy Oura Ring 4?

Amazon today at $299 (with Prime free shipping). Oura.com is MSRP $349 but includes the 30-day trial + free finger-sizer kit — worth it if unsure about ring fit.
