HealthyPi Move is a compact, wrist-worn, open-source vital signs monitor designed for developers, researchers, and health-tech innovators as well as health enthusiasts looking to own their data !
It offers full access to physiological signals such as ECG, heart rate, SpO2, temperature, blood pressure trends, and EDA/GSR, all without cloud dependencies or data restrictions. All data is stored locally and can be accessed directly through open APIs and developer tools.
Built with cutting-edge sensors and powered by the Nordic nRF5340 dual-core MCU, it’s ideal for building, testing, and exploring new ideas in digital health, biosignal analysis, and activity monitoring.
The HealthyPi Move comes ready for everyday use and research applications, in one device.
Features:
- Open-Source Platform: Full access to firmware, hardware, and APIs
- Comprehensive Monitoring: Tracks ECG, SpO2, heart rate, HRV, temperature, blood pressure trends, EDA/GSR, and motion.
- Cross-Platform Companion App: Works on Android, iOS, macOS, Windows, and Linux.
- Data Control: Store and sync data locally via BLE or USB-C — no cloud dependency, no lock-ins, no subscriptions.
- Firmware Upgradable: Built on Zephyr RTOS with Over-the-air firmware update support.
- Efficient Power Management: Up to 5 days of battery life on a single charge with USB-C charging.
- Modular & Repairable Design: Built for longevity, experimentation, and customization.

Important Warning
Although HealthyPi Move has many of the features of a medical-grade patient monitoring system, it does NOT have any certifications for medical use and is considered a consumer device for CE and UKCA marking purposes. It is NOT officially approved for medical or diagnostic use. It is your responsibility to ensure your safety when using the device. Furthermore, you should never power the device from a non-isolated power source or connect it to any other medical devices that are not isolated from the mains power supply. If you are planning to use the device for medical purposes, FDA or IRB approval is required. Please consult with your local regulatory authorities for more information.
