Leave a Review Camera Heart Rate Variability
utterly useless app
ALWAYS measures my heart rate in the 110 range when it's normally 70s to low 80sCancels end
improved but broken
The new interface is much improved, but the app now crashes frequently. In particular, the "compare" feature is completely broken. You cannot scroll through your recordings, and selecting one kills the app.
Would also be nice to be able to send feedback through the app rather than through reviews!Show less3xpl3t2v3d3l3t3d
Needs bug fixes
New re-design crashes every time I am in the middle of a readTmoney201202
NOT there yet! I'd give it more stars if I could get a refund! 😁
Recordings don't show up in display, but if you tap on the blank section it selects it blindly.
Way too confusing. Doesn't give you s simplified reading of your HRV. Unless you are a cardiologist, you'll need to do some research and educate yourself to read it!MoxMachine
Now it works! (Mostly)
At first, the app would only provide the rr intervals data. Now, for whatever reason, the other features work as well. But I still can't compare sessions within the app. This is disappointing, but I do like the fact that this is the only camera hrv app that gives AVNN, SDNN, rMSSD, PNN50, LF, HF and LFHF data.Show lessSabotajmahal
Close, but still not there
Marco’s doing great things for iPhone HRV apps, but this app needs some work.
Key issues:
- There’s no HRV readout. Seriously. There’s a bunch of HRV component measurements, but nowhere (NO where) in the app does it provide an HRV readout. Look up at the screen shots. You won’t see it.
- No recent updates or bug fix releases - it’s been about 7 months… that’s too long.
- The graphs look good, but there aren’t any horizontal axis labels, so it’s not clear what the graphs mean.
- That diamond icon button… what does it do?
I’d be willing to be that this app could be great if it had a few updates.Show lessjeffme
Not what I expected!!!
I wanted an hrv app that doesn't need the Bluetooth chest strap and be able see weekly and monthly trends of rMSSD data. This app does give you a rMSSD value but there is no avg. or any type of trend that would allow you to see your recovery for future training. The app description describes being able to compare 3 recordings, but it also states it creates plots of the data implicating more than three data points. When trying to find instructions for how to use the app you are provided technical info on the accuracy of the data the app collects, not user instructions. The app works, but the user interface is clumsy, you are provided with data that is not organized in a manner for easy comparison for the purpose of reaching training goals, and user instructions are very minimal for a very un-intuitive app.Show lessMensa bound
Training Aid for a Winning Performance
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.Show lessScubatwig

Impressive app
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.Show lessEvidence based police
