Camera Heart Rate Variability at Mac App Store analyse

The Interface ist pretty, yet designed for scientists, with an additional diploma to be able to run this App. I could not make use of this App and am trying out "breathcoherence+". May be, thatll work...

I was interested in measuring my HRV to track my recovery and this app was not expensive, and didnt require any equipment. It doesnt work at all! It displays double whatever my heart rate is at the time, and doesnt want to record most of the time. When it does record, there is nothing in the other tabs; most importantly, it doesnt calculate my HRV which is why I bought it in the first place. I tried so many times, an even kept my finger on the camera for 2 minutes. Anyway, hopefully I have prevented anyone else from buying the app.

Im very sorry to say this app is very inaccurate and inconsistent. I work with a team physiologist in my training and weve been testing this for ease of use compared to chest strap and watch monitoring but its not accurate and not worth the money. If I was consistent then it would still work but one test gave me a measurement of 102 and seconds later the test gave me a 51, ridiculous. So disappointed

I am a cardiologist exploring new ways to use smartphone as a diagnostic tool. This app is one of the best example of “iPhone as diagnostic tool” I have found. The design of this software is more sophisticated than other heart rate devices in the app store. The smoothing algorithm with cubic spline method is ingenious. The programmer validated his HRV measurement with validated clinical instrument and this enhanced the trustworthiness of his method. One small piece of advice: Bland-Altman plot and paired t-test should be used to compare the camera HRV with the clinical gold standard measurement. Overall, I am really impressed by its sophistication. I wish you good luck in your future project.

Logging to Dropbox does not work for me. Bummed.

Great app to manage your HRV without a HR monitor so you can execute an endurance sport training program without overtraining. I used this app for the last 3 months of my prep for the 2014 Boston marathon. I am a 56 year old female who wanted to run under 4 hours. Injuries due to over training kept my performances in my last 5 marathons between 4:01 & 4:06. Using HRV to assess the state of my nervous system (relaxed or stressed) I could better manage the level of exertion as well as rest in my daily training sessions. Result: 3:46:02 Boston Marathon which ranked me 56 of 768 in my division. A winning performance for this weekend athlete.

Looked really promising and maybe it is but I wouldnt know since it is absolutely not useable. App has never once gotten even a single reading because it crashes every single time you begin the process. Fix this thing asap or refund my $4. Update.. Looks like they deleted my bad review upon the new release however it STILL doesnt work. Crashes instantly every time. The app itself looks great but how would anyone know if they cant work out the bugs and get it to function??
