## What is HRV Train?

HRV Train is a simple and effective heart rate variability biofeedback app that you can use to to reduce stress and increase resilience. HRV Train also keeps your data private. The app does not send any of your data off the iOS device unless you specifically email it to someone.

HRV Train is similar to HRV Trace, but it lacks any audio or video recording capacity within the app. HRV Train was created at the request of people who did not need the recording capability. THERE IS NO UPGRADE PATH FROM HRV TRAIN TO HRV TRACE as the database structures for these apps are completely different. If you know you want to use audio/video recording with your heart rate trace displayed on the video, then you should get HRV Trace.

HRV Train displays your beat-to-beat heart rate and activity level in real-time on the screen. The shape of the heart rate graph can give you immediate information about your stress level. Certain shapes are associated with higher states of stress and certain shapes are related to lower states. By using HRV Train to see your heart rate in real-time you can learn how to modulate your level of relaxation or activation to best suit the needs of the situation. You can learn to slow down when it's appropriate to rest and you can learn to shift into a ready state when you need to be calm under pressure.

HRV Train is meant to assist with stress-management and resilience and is not to be used to treat any medical condition.

HRV Train requires a separate heart rate monitor that will transmit heart rate data via BlueTooth LE to your iOS device. The app has been tested with the following monitors: the Polar H7 and H10, the Cardiosport TP3, TP5 and TP5+, and the Zephyr HxM Smart,

### 1/5 — Confusing

*2022-10-02*

As simple as it may look how does any of the function help?
I see BPM but the other buttons don't do anything or tell me anything g useful.. Preview of what? Is this suppose to do more than show me BPM cause my Apple Watch can do that. Is there a site or link to user guide?

### 1/5 — NO HRV READING!  DECEPTIVE NAME!

*2020-04-21*

You can see your heart rate, just like you can in many other apps (that are free), but there is no HRV HEART RATE VARIABILITY number/graph, etc...
Definitely not worth $4.99, and as they offered no free trial you have to pay to use it and realize the name is misleading.

**Developer response:** The heart rate variability or HRV is in the heart rate graph. The shape of the graph contains the information.  The description in the app store states clearly "The shape of the heart-rate graph can give you immediate information about your stress level. Certain shapes are associated with higher states of stress and certain states are associated with lower states." The app is meant for people who have learned how to use the shape to indicate their stress level.

I am sorry you spent money without understanding what the product is meant to do. I will see if I can change the description to clarify the prerequisites for using it.

The app is not free because the data is completely private to the device and only the device owner can send it via email.
