Outfit the whole roster.
Phreno puts sensors on compatible team helmets and gives coaching staff one place to review the motion each device measured across the roster.

You find out after the season.
Coaches see the impacts that stop play, but other events may never be recorded. Phreno adds time-stamped device measurements while symptoms and qualified clinical assessment remain the basis for medical decisions.
Athletes underreport
Nobody wants to come off the field. Self-reporting is the weakest link in the chain.
One athlete isn’t a baseline
A device reading gains context from that athlete’s prior measurements, but it never becomes a medical clearance threshold.
Volume is invisible
The cumulative load across a season never gets counted, only the single hits that drew a whistle.
Kit the team once.
The sensor uses an adhesive mount on compatible helmets. Check each helmet manufacturer’s guidance before mounting; athletes then pair the device with the Phreno app.

Email our teamPhreno is a monitoring instrument, not personal protective equipment. It does not protect against injury, does not replace a helmet, and is not a medical device or a diagnosis. It does not clear an athlete to return to play. Follow the helmet manufacturer’s mounting guidance, your program’s medical protocols, and the guidance of a qualified clinician.
