Name: Camera Heart Rate Variability
Author: A.S.M.A

Description

Camera Heart Rate Variability is the first app that lets you record, plot and export time and frequency domain Heart Rate Variability Features - without requiring any heart rate monitor.
Camera HRV uses a technique called photoplethysmography (PPG for short), which consists in detecting changes in blood volume during a cardiac cycle, by illuminating the skin and measuring changes in light absorption. PPG has become quite a popular non-invasive method for extracting physiological measurements such as heart rate and oxygen saturation. However, most applications today focus simply on heart rate or respiration rate.
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
Camera HRV can assess cardiac autonomic regulation through quantification of sinus rhythm variability. Since HRV aims at quantifying autonomic regulations, it can be used as marker of sympathetic or parasympathetic predominance, and therefore become relevant in many applications. In athletes for example heavy training is responsible for shifting the cardiac autonomic balance toward a predominance of the sympathetic over the parasympathetic drive, and HRV analysis attempts to quantify this shift.
Other applications span from stress monitoring, assessment of pathological conditions and even emotional regulation during financial decision-making.
Main Features:
- extracts, plots, stores and exports heart rate, rr-intervals, time and frequency domain heart rate variability features (AVNN, SDNN, rMSSD, pNN50, LF, HF, LF/HF)
- configurable time window for feature extraction (30 seconds to 5 minutes)
- automatic RR-interval correction
- event annotation
- comparison between up to 3 recordings lets you get a better understanding of autonomic regulation and sympathetic/parasympathetic activity under different contexts in a glance
- data export/storage on iTunes and Dropbox (csv format, exports heart rates, rr intervals, events and computed features). Data export needs to be performed from the history -> recording view, by clicking on the export button (bottom left).
- integration with the Health app (writes Heart Rate and Heart Rate Variability)

Export Error

When trying to export the data via email after selecting email the app closes by itself and I am not able to export the data. Please help.

Not fully functional, it seems

I get a "HRV not computed due to poor signal quality" with every attempt, no matter what I do. It would help if I had more information about what that message means.

Stopped working, red circle doesn’t appear

I paid for this and a few months later it just stopped working. I can’t speak to the science behind it but it did work as sold for those months. Low rating is due to how it stopped working and the lack of support to fix. I uninstalled and reinstalled and still not working. Cleaned my camera. Re read directions, googled. Nothing. App developer says we can tweet him, I only use Twitter for work, so. Maybe they will see this and reply? FX.

Timer won’t start

I have used this twice and now the timer doesn’t start. This is beyond frustrating.

Stopped working

I used this app for the last year and really liked it but in the last month the timer has stopped working so it only tracks number of beats per minute and nothing else. Maybe it needs to be updated to keep up with the iPhone updates?

Huge Improvement

The new version is a HUGE improvement in signal acquisition. Works much better and has more consistent analysis. I tested this against a laboratory grade HRV instrument and it was quite close. It would be a good app addition for lay people to state “normal” levels and explain the different features and how they impact health and HRV. Would also be nice to choose which studies to graph together to show trend. This is better than most consumer HRV. If you are serious about measuring you HRV and want it to be easy and accurate, you need this. Very reasonable price too.

Keeps crashing

Used to love this but now every time I measure on my iPhone it crashes

Please make it available for iPhone 7+

It would be great if it was optimized for iPhone 7+, would be a 5 star if you can make it happen.

Doesn’t work, never gets good data

I’ve had this app for a couple of years. It never worked from the day I got it, even after multiple updates. I’ve tried it numerous times, and the app hasnever been able to generate an HRV number due to “poor signal quality. “ This is unfortunate, as the companies other app, HRV4Training, is excellent and highly recommended. Use that up with a heart rate monitor and you’re golden. Ignore this app, it’s not worth your time.

It works just fine

I was skeptical to buy after reading the previous reviewers rating. But it actually works quite well. Yes, it takes a little practice and actually requires reading the instructions. But compared to a $150 chest strap monitor, this app is genius. I actually went ahead and then bought the whole package of apps by the developer because I wanted to support a great app!
