Screenless, Recovery-First — The Athlete's Gold Standard
A purpose-built screenless band focused entirely on recovery, strain, and sleep — no notifications, no display, no distractions. Continuously monitors heart rate at 100 Hz, HRV, skin temperature, respiratory rate, and blood oxygen 24/7. Worn by professional athletes across the NFL, NBA, MLB, PGA Tour, Premier League, and CrossFit Games.
Daily Strain, Recovery & Sleep Scores — Actionable Intelligence, Not Just Data
Proprietary algorithms convert raw biometrics into three actionable scores each morning: Recovery (green/yellow/red based on HRV, RHR, sleep, and respiratory rate), Strain (your cardiovascular load target for the day based on readiness), and Sleep (your recommended bedtime and duration for tonight).
140+ Habit Journal — Discover What Actually Affects Your Recovery
A unique Journal feature tracks 140+ daily behaviors — hydration, meal timing, supplements, alcohol, caffeine, screen time — and statistically correlates each habit with your personal recovery metrics. Discover which habits actually impact your sleep and performance, not just what works for the average person.
