NNOXX Inc

NNOXX Inc. sells AI-enabled, wearable muscle-oxygen and metabolic sensors that stream real-time performance data to a companion mobile app. Hardware bundles run $399-$699, situating the brand in the premium tier for consumer fitness tech. Sales are direct-to-consumer through nnoxx.com and select specialty-sport retailers. The company’s USP is the first consumer sensor that non-invasively quantifies nitric-oxide bioavailability alongside muscle oxygen saturation, giving users a live “NO Score” that predicts fatigue and recovery windows. The device clips to a calf sleeve, syncs with Garmin, Apple and Strava, and is used by NFL teams and Olympic cyclists for in-workout pacing and post-session redox tracking. Target buyers are data-driven endurance athletes (runners, cyclists, rowers) and strength coaches who already track HRV, VO2 max and lactate but want earlier, muscle-level warning signals. The brand speaks to the “quantified-self” ethos: train smarter, delay fatigue, validate nutrition or nitrate-loading protocols. NNOXX competes in the crowded field of wearable biomeasurement, yet differentiates by moving the measurement site from wrist or chest to working muscle and by adding a proprietary nitric-oxide metric that legacy optical sensors cannot deliver.
