HACK Lab HRV

HACK Lab HRV is a heart rate and HRV data recording tool designed for use with compatible Bluetooth Low Energy heart rate sensors and chest straps. The app connects directly to nearby sensors over Bluetooth and records heart rate and RR interval data in real time. Multiple sensors can be connected and recorded simultaneously, making the app suitable for structured research and data collection involving multiple participants. During each recording session, HACK Lab HRV continuously captures measurements from all connected sensors and stores the collected data locally on the device. Key features: • Scan for nearby compatible heart rate sensors • Connect to multiple sensors simultaneously • View live heart rate and RR interval measurements • Monitor the connection and streaming status of each sensor • Start and stop structured recording sessions • Record data from all connected sensors during a session • Track session duration and collected RR samples • Save completed sessions locally on the device • Review previously recorded sessions • Export recorded data as CSV files • Export detailed RR interval, heart rate, timing, and device information for further analysis HACK Lab HRV provides a simple interface for collecting heart rate and RR interval data while keeping recorded sessions organized and ready for further analysis. Technical information: HACK Lab HRV communicates with compatible Bluetooth Low Energy heart rate sensors using the standard BLE Heart Rate Service and Heart Rate Measurement characteristic. The app is intended for data recording and research purposes and is not intended for diagnosis, treatment, or clinical decision-making. Recorded session data is stored locally on the user's device. HACK Lab HRV does not transmit recorded heart rate or RR interval data to external servers. A compatible Bluetooth Low Energy heart rate sensor and Bluetooth access are required for data collection.
