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) Find out more at this link: http://www.marcoaltini.com/2/post/2014/01/heart-rate-variability-using-the-phones-camera.html ## Key features - Record and plot HRV data - Extract time and frequency domain features - No heart rate monitor required - Configurable time window for analysis - Automatic RR-interval correction - Event annotation and comparison - Data export to iTunes and Dropbox ## Recent user reviews (10 of 54) All indexed reviews: https://appshunter.io/ios/app/camera-heart-rate-variability/id788460316/reviews.md ### 1/5 — Doesn’t work *2025-01-21, version 5.0.9* Consistently says low quality, not worth it. ### 3/5 — Export Error *2022-11-29, version 5.0.5* 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. ### 2/5 — Not fully functional, it seems *2022-05-25, version 5.0.3* 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. ### 3/5 — Problem *2021-04-23, version 4.9.9* I really like this app, I tried it on another phone, too bad it doesn't work on my iPhone 6. The camera does not read my finger ### 1/5 — Doesn’t work *2021-04-03, version 4.9.8* Alway says low quality, using iPhone max pro. So have stopped using. ### 1/5 — Stopped working, red circle doesn’t appear *2021-01-17, version 4.9.4* 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. ### 1/5 — Timer won’t start *2021-01-17, version 4.9.4* I have used this twice and now the timer doesn’t start. This is beyond frustrating. ### 1/5 — Not working / no funciona *2020-10-10, version 4.9.0* La he comprado para hacer un estudio y no toma bien las pulsaciones ni me da resultados de la variabilidad de la frecuencia cardiaca. 1 de cada 10 veces funciona. Para esto no lo hubiera pagado. ### 4/5 — Stopped working *2020-08-18, version 4.8.9* 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? ### 5/5 — Huge Improvement *2020-05-01, version 4.8.5* 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. ## Frequently asked questions about Camera Heart Rate Variability ### What is this app for? This app allows you to record, plot, and export Heart Rate Variability (HRV) data using only your smartphone's camera. It analyzes time and frequency domain HRV features to help you understand your cardiac autonomic regulation, stress levels, and the impact of training. ### Do I need a separate heart rate monitor to use this app? No, a key feature of this app is that it does not require any external heart rate monitor. It utilizes photoplethysmography (PPG) by detecting changes in blood volume through your phone's camera and flash. ### What kind of HRV features can I get from this app? The app extracts and plots various HRV features, including heart rate, RR-intervals, and both time domain (AVNN, SDNN, rMSSD, pNN50) and frequency domain (LF, HF, LF/HF) features. It also supports automatic RR-interval correction and event annotation. ### What devices are supported for camera measurements? The app supports camera measurements on a wide range of iPhones, from iPhone 5 up to iPhone 13 series, including various Pro and Max models. Please refer to the app description for the complete list of compatible iPhone models. ### How can I use the data from this app? You can export your recorded data, including heart rates, RR-intervals, events, and computed HRV features, in CSV format to iTunes and Dropbox. This allows for further analysis or integration with other health platforms. The app also integrates with the Health app to write Heart Rate and Heart Rate Variability data. ## Version history (last 5 releases) ### 5.2 — 2025-10-08 minor improvements ### 5.1.0 — 2025-05-14 minor improvements ### 5.0.9 — 2024-11-04 minor changes ### 5.0.8 — 2024-03-12 minor improvements ### 5.0.7 — 2023-09-21 minor improvements ## Apps similar to Camera Heart Rate Variability | App | Rating | Price | Category | | --- | --- | --- | --- | | [CardioBot: Heart Rate Monitor](https://appshunter.io/ios/app/cardiobot-heart-rate-monitor/id1149412984) | 4.5 (10,078) | Free | Health & Fitness | | [Welltory: Stress & Heart Rate](https://appshunter.io/ios/app/welltory-stress-and-heart-rate/id1074367771) | 4.7 (131,900) | Free | Health & Fitness | | [Hearty : Heart Rate,Stress, BP](https://appshunter.io/ios/app/hearty-heart-ratestress-bp/id1490743162) | 4.5 (7,532) | Free | Health & Fitness | | [Pulsebit: Heart Rate Monitor](https://appshunter.io/ios/app/pulsebit-heart-rate-monitor/id1581114201) | 4.5 (22,440) | Free | Health & Fitness | | [Pulsedo: Heart Rate Monitor](https://appshunter.io/ios/app/pulsedo-heart-rate-monitor/id1528974993) | 4.5 (3,281) | Free | Health & Fitness | | [HeartWatch: Heart Rate Monitor](https://appshunter.io/ios/app/heartwatch-heart-rate-monitor/id1062745479) | 4.7 (13,624) | $8.99 | Health & Fitness | ## More apps by A.S.M.A. B.V. - [Heart Rate Variability Logger](https://appshunter.io/ios/app/heart-rate-variability-logger/id683984776) - [HRV4Training](https://appshunter.io/ios/app/hrv4training/id686923970) - [HRV4Biofeedback](https://appshunter.io/ios/app/hrv4biofeedback/id1504638613) All apps by A.S.M.A. B.V.: https://appshunter.io/developer/1066843463 ## Related topics [camera heart rate variability](https://appshunter.io/ios/topics/camera-heart-rate-variability) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
