Heart Rate PRO 4+

I was put off the negative reviews but decided to try it anyways.

If you follow the instructions exactly as given by the app, place your finger covering the camera AND the flash light. Do NOT press hard as it changes your blood flow pattern (regular touch) and tap measure.

Tried it on all my family members and then measured the actual pulse the good ol fashioned way and with a heart rate monitor device. The app reported a pulse within 1bpm of the actual heart rate. It worked perfectly after a workout and when resting with the heart rate ranging from 56bpm to 148 bpm and it reported 55 and 147 respectively.

Nicely done!!

A complete an utter ridiculous waste of time. I tried multiple times. I got rates varying from 52-72 after at least 10 attempts. I manually took my pulse, which is 86. I am an experienced nurse practitioner and am capable of capturing a correct heart rate (HR) manually, so this is not operator error. You’re better off checking your pulse by putting two fingers up to the front/side of your neck, apply gentle pressure and move your fingers vertically and slowly until you can feel your pulse through your carotid artery. Now using a stopwatch or a wristwatch with a second hand, begin counting the beats (wait for the second hand to hit 12, 3, 6, or 9) to making counting for an appropriate length of time easier. Options for this is to count for: a) 15 seconds and multiply the number by 4; or b) 30 seconds and double it; or c) count for the full 60 seconds. There you have it... an accurate heart rate (for FREE!). By the way, do you really trust developers unable (or too lazy) to describe their invention/app, in their ad no less, without multiple grammatical or spelling errors? For me... nope, no way! Check each of the three pages they have of “how to” directions. If you want to sell something... for gosh sakes man... proofread everything you post/write in your ad, or hire someone to do it for you. It’s just common sense to “look” professional, even if your “invention here” is worthless. I tried it because it’s free on AppAdvice, but now I will be deleting it. :(

It does its job and does it well, but it needs a continuous mode. It jumps around a lot, whereas most monitors have a sort of lag/average mode. This one (probably; can't test without continuous mode) gives your true heart rate, live.

If you're healthy and unstressed, your heart rate changes every time you breathe in or out. Most HR monitors average this number. This one doesn't do that until the very end, and I'd like to see that my live heart rate is, for biofeedback purposes.
