What to choose
If you pay for Whoop for its recovery analytics, WITU gives you a jewelry-grade tracker with medical-grade optics and drops the subscription fee — and if you want real ECG, the Patch and Chest Strap are in the same ecosystem. Whoop remains a strong choice for those who specifically value its training community.
Over 3 years a Whoop subscription is ≈ $1,000. WITU is a one-time device purchase.
