Whoop 4.0 costs $227 more than Oura Ring 4 over 24 months โ€” despite advertising free hardware. Whoop's mandatory $30/month subscription (12-month minimum) means first-year cost is $360 before the device even unlocks its features. The "free hardware" framing is the most misunderstood element of the Whoop value proposition. Use our interactive TCO calculator to model costs across 1, 2, and 3 years in USD or GBP.
