First and foremost, thank you for your continued support and enthusiasm throughout our journey. Since fulfilling all the orders, we’ve been closely listening to your feedback, tracking real-world usage, and working diligently to improve both the firmware and mobile app experience.

We’re happy to announce the release of a feature-packed update for your HealthyPi Move device. This upgrade brings significant enhancements to connectivity, data recording, user control, and real-time monitoring, making your HealthyPi Move more capable and intuitive than ever before. This update also restores most of the features that were missing in the initial release, and adds several new ones that we believe will greatly enhance your experience. Let’s walk you through what you can expect in this major update.

Improved new screens design and navigation

The main screens are now more intuitive and user-friendly, with a fresh minimalist design that makes it easier to navigate through the various health metrics and settings. The new layout is designed to provide quick access to the most important information only, without any unnecessary clutter.

More screens will be added in the future, and behind the scenes, we’ve also made significant improvements to the underlying codebase to make is easier to add new screens and features in the future. A few more screens are already in the works, including sleep tracking, hrv monitoring and more trend displays on the watch itself.

Backed by a powerful new mobile app

The HealthyPi Move mobile app also has undergone a complete overhail, resulting in a more intuitive, responsive, and feature-rich experience. The new app is designed to seamlessly integrate with your HealthyPi Move watch, providing you with real-time health insights and control over your device. Current functionality include the ability to get signal trends, download ECG records, calibrate blood pressure, and more—all from the convenience of your smartphone. This release also greatly improves the app stability in terms of connectivity and data handling.

Blood Pressure Trending (BPT) Support

We’re excited to introduce the first version of Blood Pressure Trending (BPT) support in the HealthyPi Move app. This feature allows you to track your blood pressure trends over time using non-invasive, cuffless estimation methods based on pulse transit time and waveform analysis. This makes use of the finger based PPG sensor, which is included along with the HealthyPi Move and can be plugged into the onboard USB-C port only when required. Finger PPG is a well-established method for estimating blood pressure trends, and we’re thrilled to enable this capability to the HealthyPi Move.

BPT calibration is now available in the app, allowing you to set your baseline BP values using an medically approved blood pressure monitor. This is a crucial step to ensure that the HealthyPi Move can provide accurate relative changes in your blood pressure readings. Once calibrated, the app will display your BP trends alongside other health metrics, providing a comprehensive view of your cardiovascular health.

Note: This is not a replacement for medically approved BP monitors, but rather a way to track relative changes (from your calibrated level) in your blood pressure over time.

Live Stream Physiological Signals

The latest update brings robust real-time signal streaming to the HealthyPi Move app, letting you view multiple physiological parameters directly from your device. Whether you need to look at the signal for troubleshooting, research, or just curiosity, this feature provides a live view of your health data right on your smartphone. You can now live stream:

• ECG (Electrocardiogram)
• Wrist PPG (Photoplethysmography)
• Finger PPG
• GSR (Galvanic Skin Response)

Note: Streaming begins only when there is proper physical contact between the sensor and the body:

• Finger PPG activates when your finger is in contact with the fingertip sensor.
• Wrist PPG, ECG, and GSR require contact with the skin at the appropriate wrist location.

Record and download ECG

With this latest update, 30 second ECG recording can be taken on the HealthyPi Move and is stored internally on the device itself. The new HealthyPi Move app now allows users to view the list of all stored ECG recordings on the device, download them to their mobile device, and save them in CSV format for further analysis or sharing. This feature is particularly useful for users who want to keep a history of their ECG events or analyze heart activity trends over time.

Whenever you initiate an ECG measurement on the Move Watch, the device captures and stores a 30-second raw ECG recording in its internal memory. These recordings remain saved on the device until they are manually fetched or deleted. Using the Fetch Recordings option in the app, you can:

• View a list of all stored ECG recordings available on your Move Watch
• Select and download individual ECG records of requirement directly to your mobile device.
• Save downloaded records locally in CSV format for sharing, or further analysis.

SpO2 can now be measured using both wrist and finger PPG sensors

We always had two PPG sensors on the HealthyPi Move watch, but the initial firmware only supported wrist PPG for SpO2 measurements. We’ve now added the ability to choose between two sources of PPG for SPO2 measurement:

• Wrist PPG: The default method using the wrist-mounted PPG sensor. This is suitable for most users and provides a good balance of comfort and accuracy during daily activities. However, it may not be as accurate during high-intensity activities or when the wrist is in motion.
• Finger PPG: An alternative method using the fingertip sensor for more accurate readings. The Fingertip sensor needs to worn on the index finger for accurate readings as mentioned in one of our very early updates

This flexibility allows you to select the most suitable method based on your activity level, comfort, and accuracy needs. The device will prompt you to choose your preferred SpO2 sensor method every time a recording is initiated, ensuring you have control over how your SpO2 data is collected. We recommend using the finger PPG sensor for more accurate and stable readings. The wrist PPG sensor works great for heart rate monitoring though.

Seamless BLE Pairing & Auto-Reconnect

We’ve added Bluetooth Low Energy (BLE) pairing functionality that enhances security of the connection between your HealthyPi Move watch and the mobile app. It also simplifies the user experience by allowing the app to automatically reconnect to your HealthyPi Move watch without needing to reselect it each time you open the app.

When you first connect your HealthyPi Move watch to the app, you will be prompted to enter a pairing key displayed on the Move. This pairing key is random and ensures that only your app can communicate with your HealthyPi Move watch. Once paired, the app will remember this connection, allowing for quick and secure reconnections in future sessions.This means:

• Secure connections to keep your data private
• No repeated selection each time you open the app
• Faster auto-reconnect when performing syncs, calibrations, or streaming
• Smoother experience when switching between features like live data and records

This is a foundational step for making your interaction with HealthyPi Move more fluid and hassle-free. All future updates will use the same BLE pairing method, ensuring a consistent and secure connection experience.

Note: As of the time of writing this update, the syncing of data from the watch to the app is still done only when the "Sync" button is pressed in the app. We are working on making this automatic in the future, so that you can just open the app and see the latest data without needing to press the sync button. Expect this in a future app update.

Behind the Scenes: Software Stability & Performance

We have also made some significant improvements to the underlying software architecture of both the HealthyPi Move watch and the mobile app. These changes are designed to enhance performance, stability, and responsiveness, ensuring a smoother user experience overall. The codebase has also been refactored to make it easier to maintain and extend, allowing us to add new features and improvements more quickly in the future and more developer friendly.

• Improved BLE communication stability
• Refined file handling and sync logic
• Smoother navigation in the Android app
• iOS app is under final stage of review
• Developer-friendly updates to the firmware codebase

A few caveats to note

While we’ve worked hard to ensure a smooth experience, there are a few caveats to keep in mind. These will be quickly addressed in future updates, but we want to make sure you knew what to expect now.

• Power Consumption: The new features, especially live streaming, may increase power consumption. We recommend charging your HealthyPi Move regularly to ensure uninterrupted usage. The power management algorithms have not yet been fully optimized for the new features, but we are actively working on improving battery life in future updates.
• iOS App: The iOS app is currently under review and will be available soon. We’re working closely with Apple to ensure it meets their standards.
• Firmware Update: Ensure your HealthyPi Move watch is updated to the latest firmware version to take full advantage of these new features. We will also do quick bug fix updates in the coming weeks to address any issues that may arise. The firmware update DFU process from the app is still in beta, so we recommend using the manual DFU process for now. Instructions for this can be found in the HealthyPi Move documentation.

We’ve prioritized stability, responsiveness, and compatibility in this update to ensure every user—whether a developer, hobbyist, or everyday wellness enthusiast—has a positive experience.
