Description

The first scientifically validated Heart Rate Variability (HRV) app. HRV4Training provides HRV based insights to help you quantify stress,
better balance training and lifestyle, and improve performance. HRV4Training does not require a heart rate monitor, since it can accurately assess your HRV using the phone's camera.

HRV4Training also works with Apple Watch, the Oura ring and all compatible Bluetooth SMART sensors.

HRV4Training is also the first app that goes beyond simple measurements and provides insights on:
1) acute or day to day HRV changes in response to different stressors (alcohol, travel, sick days, training, menstruation, etc.)
2) long term multi-parameter trends to look at the big picture
3) correlations between physiological measurements and annotations
4) training load analysis, fitness, fatigue, readiness to perform and injury risk
5) VO2max estimation for runners linking the app to Strava or TrainingPeaks and using a heart rate monitor during their workouts
6) Training Polarization analysis (or 80/20)
7) Lactate Threshold Estimation for runners linking the app to Strava or TrainingPeaks and using a heart rate monitor during their workouts
8) Weekly and monthly summaries to track progress.

All data is processed inside the app in order to provide you with actionable interpretations that can help optimizing your training plan and performance.

Supported devices for the camera measurement: iPhones 5, 5S, 6, 6S, 6+, 6S+, SE, 7, 7+, 8, 8+, X, XS, XS Max, XR, 11, 11 Pro, 11 Pro Max, 12 mini, 12, 12 Pro, 12 Pro Max, 13 mini, 13, 13 Pro, 13 Pro Max, 14, 14 Plus, 14 Max, 14 Pro, 15, 15 Max, 15 Pro

Currently unsupported devices for the camera measurement: iPhones 4S, iPads and iPods - These devices require a chest strap.

Not acurrate reading

danielsilva04 on

In the first days, the reading was allways optimal, but after a couple of days, started to be annoying the time I lost to take the reading on the camera, lots of failure reading, making the data not accurate, on iPhone 11 pro...

Text size too small

luiscoentro on

I like the app but the text size is too small. I have write a mail to the app team, receive a nice response but nothing change.

Every day app!

Very good App

xameqo on

I use it every day and it returns lots of stats about my physical condition. I love it and I would like to experiment more.

A must for the serious athlete

imigra on

As a master runner preparing to take on the 6 Marathon Majors for a top 3 spot in my age category, I'm always looking for ways to optimize my training. While researching HRV, I found this app and all the info written by its authors. This goes way beyond a simple HRV recording (that can be done with the iPhone's camera btw) and provides a wealth of information and stats to guide you through your training. Highly recommended.

Pure Science in Sports

joaoamalmeida on

Excellent work behind a lot of numbers and interpretations to let us more and more motivated to training. Thanks Ps: first app that I payed, and i'm sure she deserves it.
