HRV Train 1.2

HRV Train is a straightforward and effective heart rate variability biofeedback application designed to help users manage stress and enhance resilience. One notable feature of HRV Train is its commitment to user privacy; the app does not transmit any data from the iOS device unless explicitly shared via email.

Compared to HRV Trace, HRV Train lacks built-in audio or video recording capabilities, having been developed specifically for users who do not require such features. It is important to note that there is no upgrade path from HRV Train to HRV Trace due to fundamentally different database structures. For those interested in incorporating audio and video with their heart rate recordings, HRV Trace would be the recommended option.

The app provides real-time visualization of beat-to-beat heart rate and activity levels, allowing users to readily assess their stress levels based on the shape of the heart rate graph. Specific patterns correlate with varying states of stress, enabling users to better understand and modulate their relaxation or activation levels according to situational needs. This can facilitate appropriate responses, such as slowing down during rest or preparing for calmness under pressure.

HRV Train is intended primarily as a tool for stress management and resilience enhancement, rather than for medical treatment or diagnosis.

To use HRV Train, a compatible heart rate monitor is required for transmitting data via Bluetooth LE to the iOS device. The app has demonstrated compatibility with several monitors, including the Polar H7 and H10, Cardiosport TP3, TP5, and TP5+, as well as the Zephyr HxM Smart.
