LabRecorder

A simple Android app to record heart rate (HR) and RR-interval data simultaneously from two Polar BLE heart rate sensors.

How to Use

Install the App: You can install the app directly using the app-release.apk file in the repository. Grant the necessary Bluetooth permissions when prompted.
Enter Group ID: Type a unique name for your recording session in the Group ID field.
Scan & Connect: The app automatically scans for Polar devices. Once found, they will be auto-assigned. Click Connect and wait for the status to change to "Connected".
Record: Click Start Recording. You can log events using the Start/Stop Interval and Mark Timestamp buttons.
Stop: Click Stop Recording to save the session.

Recorded data is saved as .csv files on your device. You can find them in the following directory:
