Decision-making changes under stress.
In high-pressure environments, stress can affect judgment, attention and response – often before we consciously recognize it.
A Proven Connection
Key decisions should never be made under stress. Yet first responders such as police officers, firefighters and healthcare workers must make split-second decisions every day – without knowing if they’re already under stress. In fact, half of all mistakes made on the job may be the result of decision-making compromised by stress.
The Right Frame of Mind Matters
When we’re in the right frame of mind, we make better decisions. But how do we know when we’re in the right frame of mind? It’s actually quite simple. The best (and only) objective way to measure stress is by tracking heart rate variability (HRV).
Here’s how we make the invisible measurable.
From data to action.
Code 4 doesn’t stop at showing physiological data. It labels stressors, triggers and recovery patterns, then turns those signals into information people can understand and act on.
Stress Testing at its Best
The first to use A.I. to manage and predict stress levels, Code 4 Pro is an extremely accurate and versatile tool for stress management and mitigation.

HRV & Stress Management
See stress before it becomes burnout. Code 4 reads heart rate variability in real time and turns it into guidance that adapts as your data changes – helping users understand stress, recovery, and resilience over time.
Multi-User View Dashboard
One dashboard gives teams a shared view of performance – who may be under stress, how they’re recovering, and where attention is needed most.
