Worn Behind the Ear.
A complete head impact monitoring ecosystem. Designed to keep athletes safe without changing how they play.
Discreet. Comfortable. Accurate.
A small sensor worn behind the ear with a skin-safe adhesive. No mouthguards, no helmets — just stick and play.
Everything Your Team Needs
Team charging case, mobile app for sideline alerts, and a web dashboard for long-term tracking — all in one kit.
Simple Setup. Instant Detection.
Get your team protected in three easy steps.
Attach
A sensor is given to each player on the team. It's attached with a simple adhesive behind the ear. The sensor is worn during training and matches.
Monitor
While playing, the sensor sends head impact data to the sideline app in real time, so coaches, team staff and parents always know what’s happening on the pitch.
Review
Alerts appear on the sideline app the moment an impact passes your threshold. You decide what happens next. A full history of each player’s impacts is available in the app.
Objective Data for Subjective Decisions
Our advanced sensor technology converts on-field impacts into actionable objective insights, specifically calibrated for the demands of contact sports.
Live Sideline Alerts
Instant transmission of impacts above your threshold to pitch-side, so staff can make informed decisions quickly.
Sport Agnostic Design
A small sensor that simply sticks on behind the ear. No mouthguards or helmets required. Works for any sport.
Universal Fit
No custom moulds required. Sensors can be shared across the entire squad and reassigned between players seamlessly.
Linear and Rotational Kinematics
Validated measurement of both linear g-forces and rotational acceleration to capture the full impact profile.
Cumulative Load Monitoring
Track total head impact exposure over time to manage contact load in training and games.
Secure Cloud Storage
GDPR-compliant data storage, keeping a long-term impact history for every athlete across multiple seasons.
Quantify the Unseen
Not all impacts are seen.
Live G-Force Telemetry
Continuous stream of linear acceleration data sent from player to sideline.
Rotational Kinematics
Secondary analysis of rotational acceleration, a key indicator in concussion mechanics.
Real-Time Detection
Impacts are detected and recorded instantly, giving sideline staff immediate visibility.
