Human hearts still beat the same way they did 18 months ago :smirk:

Problem with this sort of thing is that your heart rate is likely to increase just by thinking about it being measured lol.

A negative aspect of this app is that my flash becomes extremely hot to touch after a few seconds.
I think it depends on the phone as well, seems like the LG G2 gets extremely hot in 2-3 seconds.

It's very accurate. However, a lot of people can't read, it says 'don't apply too much pressure on your finger, just barely touch the flash/camera'.
Natural tendency is to preas as much as you can thinking this will increase accuracy.
One review doesn't prove it's not working. Get the free version and try for yourself?

Surely this can't be accurate.
Has anybody done a comparison using a heart rate monitor (and chest strap)?

It turns your flash on, so light shines through your camera. As your heart beats, the pulse changes the colour of your finger, which the camera sees.
No reason why this can't be accurate!
Obviously not so convenient for tracking a run though, compared to a chest strap...

It's a good 10 bpm (plus or minus) out compared to my father in laws for purpose heart monitor.
We've only been playing around with it today though, so perhaps his fingers are too fat for my phone camera or something...

Yes. I used to work in the sports industry and we had HR monitors that were used for athlete testing. These were super expensive calibrated things. Tried the app one day on my iPhone and wore the chest strap at the same time, and the app was spot on. It's relatively simple tech to be fair. Every time you have one circulation of blood (ergo heartbeat) your skin flushes a little. Too subtle to be picked up by the human eye but easily detected by a camera lens pressed up against your finger.

I have an epson HR monitor now, it is accurate compared to this. I have POTS and my HR was 160 walking around Sainsbury's, this app helped me realise that I should go to my GP!

Thanks, I'm pretty fit, but have a very active life style as well as exercising, guess I'm lucky having a job where I'm on the move all the time as well.

The max I seem to reach is about 110, that's during long hill climbing 1:5.

I've used this app for a few years, I have the free version not sure what the difference is.
To answer a few questions, this app is very accurate and is usually spot on with dedicated sports hrm with a chest strap, it may fluctuate a couple of beats either side but usually sync up after a few seconds so well within accuracy tolerances.
It stores a few of your last few results (but not many, so maybe this paid for app will provide more), so you can keep track of your results.
This app is perfect for checking resting heart rate first thing in the morning whilst still in bed, it's accurate and fast.
This app is not so good for use whilst exercising, it doesn't give continuous readout and is fiddily to use so a hrm with chest strap is better ( some health monitors/ smart watches are good without needing chest strap).
From my experience most hrm built into exercise machines are very inaccurate and often give wild results.

Definitely not accurate, I've tried two different fingers and mine was 184 and then 123 lying down! Granted I'm pregnant but that's ridiculous! I've got a blood pressure machine so just checked it accurately and it's 104. I wouldn't bother wasting 10p!!!

If you're gonna use it for monitoring heart rate during exercise a chest strap would be better. This app seems like a good idea until you actually try to use it... have to stop exercise, turn app on, wait a few seconds to load, try to get an accurate reading (easier said than done if you've been going flat out). Can be a bit of a pain in the butt (I speak from experience). A chest strap makes life much easier and can be had for £13 from ebay or even Aldi.
For occasionally checking heart rate for medical reasons (someone has a known heart arrhythmia they need to monitor, on chemo and want to watch for early signs of infection etc etc) then this might be worthwhile (but if you read the blurb that's not how it's being sold).
That's just my opinion as a doctor who exercises, sometimes uses a chest strap and has a masters degree in Sports and Exercise Medicine.

Yep, the medics were concerned at how low my hr is, resting is usually mid 30s but I do a lot of cycling and exercise/gym, and I'm on my feet pretty much all day at work so guess it's ok.
It's carrying that huge phone around that's straining your heart.

He's right to say that the fitter you get the lower your heart rate will be but don't work that backwards. If you've a relaxed HR of 40, but are overweight, don't exercise, smoke/drink...blah...blah don't then assume you're fit - it's a real sign of a potential problem.
I believe Seb Coe had a relaxed heart rate of 28 at his peak. Just sayin'...
Sorry - boring post.

Been using this for years. Type of phone can vary the accuracy I guess due to flash and lens position.
Usually if you make sure your finger is over the flash and over about 90% of the lens you get spot on results. If you press your finger hard over the lens it doesn't seem to work very well.
Compared to my actual chest belt heart rate monitor it is usually within 1 or 2 BPM.
It actually responds much quicker than my proper heart rate monitor though so results don't always tally if heart rate is changing

that's because when you press hard it stops the blood flow into the finger :wink:

Best of the apps I've tested. Even the free version lets you keep taking readings but just limits your history to the last 5.
Once you've learnt how to use it properly and know how to position your finger it's absolutely accurate. You can see the little heart symbol matching the bumps of your heartbeat.
