The StressChecker offers three ways to measure, suited to different moments in your day.
90 seconds
Your daily measurement. At rest, at a fixed time — in the morning, for example. It gives you your Relax Index plus personal feedback. Those who do this consistently recognize patterns over weeks and months.
90 seconds
A measurement in a concrete situation. Before an important conversation, after work, after exercise. This shows you how your body responds at particular moments.
3 to 5 minutes
An active session in which you practise with your breathing. You see in real time how your heart rate responds — and how you can bring about relaxation yourself.
Not just a number — a readable account of what your body is showing.
A clear value on a scale of 0 to 10, based on the combination of your heart rate and heart rate variability. No abstract figures — a directly readable indicator.
With every measurement you receive a short, personal reflection. What stands out? What does this measurement say in relation to your self-assessment and earlier measurements?
Before each measurement you answer a few short questions: how relaxed you feel, how vital, and what is on your mind. This gives every measurement context — not just a number.
Your own estimate is shown alongside the objective measurement. Sometimes they match, sometimes they don't — and it is precisely that difference that is instructive.
The monthly subscription is the ideal start if you want to try StressChecker out flexibly first, without committing for a whole year.
You measure with StressChecker primarily for yourself. If you work with a coach, therapist or naturopath who also uses StressChecker Pro, you can pair your measurements with their Pro account.
Your home measurements then appear automatically in their dashboard — so the guidance between sessions is supported with real data. The pairing happens only with your explicit consent.
Because you pay for the subscription yourself, your measurements, your account and your history remain fully preserved even after a course of treatment ends. You can continue with a new coach — or on your own.
The pairing happens with your explicit consent. You can end it at any time — when a course of guidance concludes, when you switch coaches, or simply because you want to.
StressChecker works independently. A pairing is an option, not a requirement. You can start at any time — alone, or together with a professional.
With the annual subscription you pay € 69 for 12 months of access — that works out to € 5.75 per month instead of € 6.95. You can switch from the monthly to the annual subscription at any time.
A compatible heart rate monitor. StressChecker works with any Bluetooth heart rate monitor (e.g. Polar H7, H9 or H10) and with our own Bluetooth heart rate monitor (€ 49.50) or USB heart rate monitor (€ 37.50). The heart rate monitor is not included with the subscription — you buy it once.
A device with a browser. On a Windows PC or Mac you can use both heart rate monitors; on Android and iPhone/iPad only the Bluetooth heart rate monitor. iPhone and iPad users download the free Bluefy browser from the App Store; all other devices use Chrome, Edge or Firefox.
No installation, no apps. StressChecker runs directly in the browser — you can get started right away.
