Phreno

Phreno pairs with the Noggin headband to track head impacts in real time. Built for athletes who play hard — football, skiing, mountain sports, and action — Phreno captures every significant hit so you can train smarter and play with confidence. WHAT'S INSIDE • Dual-Sensor Precision — A high-G accelerometer and IMU gyroscope measure both linear and rotational forces on every hit. • Real-Time Impact Alerts — Instant notifications when a significant hit is detected. • Always-On Smart Design — Noggin activates automatically with your gear and powers down after sessions. • Offline Reliability — On-board memory stores hits when you're out of Bluetooth range. Sync later. • Long Battery Life — Up to 7 days per charge. USB-C rechargeable. HOW IT WORKS 1. Charge and pair your Noggin headband with Phreno over Bluetooth. 2. Wear Noggin under your helmet or gear. 3. Review impact history, g-force data, and session stats on your iPhone. DISCLAIMER Phreno is not a medical device and is not intended to diagnose or treat concussion or brain injury. Always consult a qualified health professional after a significant impact.
