How It Works

Simple Setup. Instant Detection.

Get your team protected in three easy steps.

01

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.

02

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.

03

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.

The Ecosystem

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.

Live Demo

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.
