Airo works by measuring the state of your nervous system on a second by second basis. It is the complete solution to tracking your mental strength, whether you want to increase cognitive performance or relieve stress.

It is a tool for self-regulation. And like most tools, there is a process here. It is:

Science of tracking

Airo fundamentally works by measuring the state of your nervous system on a second by second basis.

Your body looks at most situations you meet - people, red lights, losing your phone, meetings, seeing your lover, breaking up, and even your own thoughts - in two ways: "fight-or-flight" or "rest and digest".

"fight-or-flight" means your sympathetic nervous system will be turned up.

“rest and digest" situation means your parasympathetic nervous system will be more active than the other one.

Airo works by tracking which of the two nervous system is firing, and it does so every second. It measures your Heart Rate Variability (not to be confused with Heart Rate) - HRV is the variation in the duration of your heartbeat, which caused by your nervous system.

This is how Airo tracks your mental health state - whether it be minor depression and anxiety or major mental illness or high performance. The scientific evidence is overwhelming. Scientists across the world have studied HRV for depression, anxiety, weight-loss, PTSD, stress, heart surgery and it is astounding how well it works.

Here are some papers, in case you're like us and find papers interesting.

Ideally, you want a flexible system that is able to fight or recover as needed but the busyness of our lives has evolved far beyond what our bodies are used to. It is now more important than ever to keep the body and mind in balance.


Since Airo is tracking your body continuously, it is pretty easy to detect patterns of both stress and performance. This means that everything Airo tells you is about you - it is not calculated from some standard someone came up with for people like you. What Airo tells you is a measurement of you, for you.

Relieve Stress & build resiliency

Controlling the breathe kicks in your parasympathetic system. This means that if you were to start controlling your breathe right now, you would activate your rest & relax nervous system, and this would make you feel calm. Try it :)

All of us breathe at different rates. We also all have a specific breathing rate that has the most calming affect on us in the shortest amount of time. Since Airo is already tracking your body continuously, it can detect which breathing method gives you the most benefit. You’ll get used to that breathing rate and apply it every time you need to feel centered!

Boost Performance

Airo automatically highlights your focus point, i.e. the times in your routine where you are performing at your best (and so your nervous system is too!). This lets you think back to what made that happen. Was it the walk? The sip of water? The phone call?

This way you can also objectively know whether you are ready to push yourself in that moment or should you do some exercises to get there. Of course, Airo will help you with those exercises.

Accuracy & Validation

Most wearables are based on co-relation, Airo is based on direct measurement. It is directly measuring your nervous system so there is 0 chance of error. It is being used in studies at the University of Guelph and mental health clinics in Kitchener-Waterloo area.

However, there is one case in which Airo may not work. If you are engaged in vigorous motion i.e. running, Airo will not be able to track you. This is because the up and down movement of the sensor prevents it from getting an accurate reading. But then again, if you are engaged in vigorous motion, you are experiencing stress anyways. When you stop, Airo will continue to detect your recovery patterns.


Note that Airo is continuous. That means Airo tracks you every second of every day while you are wearing it. It is the only device in the market to do this.

Works with your care provider

Airo is a scientific grade device used by health researchers of various types. We’ve built an analysis and monitoring platform. This can be used by your healthcare provider to give you feedback right away.
