How do Polsen watches work?
The Polsen watch is a health tracker disguised as a classic, screen-free watch. Powered by research-grade PPG and motion sensors, it captures your body’s response to daily demands second by second — continuously, never sampled or averaged. All your data and personalised health insights live in the subscription-free Polsen app, giving you a complete and actionable picture of your health without the distractions.
How are Polsen watches different from other wearables?
Most wearables focus on fitness metrics — steps, calories, sleep stages — and reduce everything to a daily score. Polsen watches go deeper. Powered by the Reactivity Monitor™, they track second by second how your body responds to daily demands, measuring stress frequency, recovery time, and cumulative load — nervous system metrics no other tracker captures.
The result isn’t a score telling you how you did. It’s a complete picture of what your body actually went through — and the tools to act on it before the load builds up. No subscriptions, no dopamine loops, no data sold. Just the clearest view of your health, always in your hands.
Do Polsen watches track physical activity, steps, and sleep?
Yes, Polsen watches track all the basics: activity, steps, sleep duration and stages, night HRV (heart rate variability), and resting HR (heart rate), plus, unique stress metrics continuously captured in the Reactivity Monitor™.
How are Polsen watches manufactured?
Our watches are designed at Polsen Health HQ in Amsterdam and produced in Finland. All components including our research-grade sensors are specially selected to be both durable and skin-safe. We only use high-quality materials to ensure the best experience.
Do I need a subscription to access all my data and features?
No, you do not need a subscription. As soon as your Polsen watch is out of the box, the companion app and all features are completely free to use. Your health data belongs entirely to you, and we don’t charge you for core functionalities.
How does Polsen Health manage and store user data?
We respect your privacy and never access your data unless you choose to share it. Shared data is securely stored on EU-based AWS servers (Frankfurt) with advanced encryption and is used only to improve the app and algorithms. You can download your data anytime, and we will never sell or distribute it to third parties.
Where does Polsen Health ship to?
Currently, we ship within the European Union and to Canada, Norway, Switzerland, Turkey, the United Kingdom, and the United States of America.
Customs regulations prevent us from shipping elsewhere, but we are exploring how to expand our shipping destinations to include new countries.
Our Fulfilment Team carefully packages your order at Polsen Health HQ in Amsterdam.
