How do you want to stand in life — and what does your body say about it?

Lifestyle Monitors builds instruments with which you explore for yourself how your daily life affects you. No quick fix, no finger-wagging — an exploration at your own pace, with instruments that do their work and then step aside. We have two: the StressChecker, which measures your daily tension in 90 seconds, and the Healthy Lifestyle Monitor, with which you learn to read your whole lifestyle.

How do you still know what is yours, in a world that constantly demands your attention?

What does your body say, before your mind notices?

Our instruments make visible what your sensing system often no longer perceives in the hectic pace.

For yourself, for your practice or for your organization — our instruments follow three routes:

Why now

The pressure on our daily functioning has fundamentally changed over 15 years. Two influential thinkers describe exactly what many people feel — and why an honest measurement of your tension is more valuable today than ever.

Byung-Chul Han

Philosopher — The Burnout Society

We live in a performance society in which we exploit ourselves. The pressure no longer comes from the outside, but from within. Burnout and exhaustion thus grow unnoticed — until the body itself gives the signal.

Hartmut Rosa

Sociologist — Acceleration & Resonance

Modern society demands continuous acceleration. The pace at which we live drifts further and further away from what body and mind can keep up with. Without pauses and honest signals, contact with what is good for you disappears.

What this means for you

In a world that only gets faster, the ability to take your own body seriously is no longer a luxury. A short, honest measurement shows what your sensing system no longer perceives in the hectic pace — before it becomes a problem. That is what our two instruments are for: the StressChecker for your daily tension, the Healthy Lifestyle Monitor for the bigger picture of your lifestyle.

Two instruments, one measurement basis

The StressChecker and the Healthy Lifestyle Monitor share the same proven measurement — but they look at different scales. One zooms in on your day, the other on your lifestyle over the weeks. Choose what fits you, or combine them; they reinforce each other.

StressChecker

Insight into your daily tension — in 90 seconds.

With a heart rate monitor you measure how daily stimuli, your way of thinking and your lifestyle work through into your autonomic nervous system — and thus into how you feel. We call that result the Relax Index: a number to compare measurements, not a verdict.

In dialogue with your own answers you learn whether stress or fatigue lies behind your tension. Ninety seconds a day, and after a few weeks you see your own patterns.

From €6.95 per month. Runs in any browser, no installation.

Healthy Lifestyle Monitor

Learn to read your Inner Compass.

The Healthy Lifestyle Monitor (HLM) makes your Inner Compass visible — body, emotions, thoughts and conscience. Each day you rate eight lifestyle factors in two minutes, from sleep to meaning. This is how you discover what fits you and what works — not through willpower, but by becoming aware of who you want to be. A mirror, not a finger-wag.

For those who seek the bigger picture and want to begin change with themselves. Optionally you measure the same Relax Index — with the same sensor.

From €9.95 per month. Also in the browser, on any device.

For your practice or your organization

Do you work as a coach, therapist or lifestyle professional? Both instruments have a Pro version with which you guide clients remotely — on the basis of their own data, with respect for their privacy. And for health days and events there are measurements on location.

No hype — 15 years of practical experience

The measurement method behind both instruments is not new. Since 2010, the StressChecker has been used by private individuals, coaches and health professionals — in the Netherlands, Germany and beyond. That same proven measurement forms the basis under the Healthy Lifestyle Monitor.

The StressChecker measures your autonomic nervous system through heart rate and heart rate variability, in accordance with the guidelines of the Task Force of the European Society of Cardiology (1996) for HRV measurement. Not a medical device, but a reliable instrument for self-reflection and professional guidance.

Confidentiality as the starting point

Our instruments revolve around the most personal question there is: how you are really doing. That only works if you can be sure that this information stays with you. You pay a subscription — that is our business model, so your data does not have to be.

No advertising, no data sales, no profiles for third parties. Your data is stored on our own server in the Netherlands, and you keep control.

Why we build this

Behind our instruments stands a diagnosis of our time and a different view of self-reflection: the Columbus Catalyst Code. Lasting change does not come from willpower, but from becoming aware of who you are — and who you want to be.
