NOTE: Works best on iPhone 4/4S/5/5S/6/6S/7/7+ because it has flash. On iPhone 3GS and iPod touch the app has to be used in good lighting.

NOTE: Make sure that your fingertip completely covers the camera lens. Press gently, since pressing too hard reduces blood flow in your finger and it's harder to get a result. Make sure that your fingers are not cold. This app is for recreational and fitness use only!

Really works as far as I can tell, and everything lines up with doctors' office readings and old-fashioned pulse measurements

Edit: yes it does what it says on the tin but "instant" is somewhat of a misnomer now. When you open the app it prompts you to make an account, and to skip that you have to find a barely visible plain text button. Then it sends you to an ad for their premium service and like two other ads before actually dropping you into the app. Its annoying when you just want a really quick look in between sets. I'm not mad, I know they have to finance development somehow and I'm not pressure aware of a better alternative. But with these updates I would no longer call it "instant".

Too many pop up ads makes it cumbersome

Too many pop up ads to be able to use. Don't bother with this unless you just try it once and then be willing to buy how ever many things required to make this usable. It says "free," but the price is that the ads won't let you see your results (I got a glimpse but before I could focus to read the smaller print it was covered up). The pop ups are full-sized blocking you from using it, and unless you click in just right spot you will find yourself redirected to other windows. I exercised and took my pulse but an ad blocked the results. Then I hit the wrong spot and was in the Apple Store, closed out of that, reopened the app only to have to start over. By then I had rested too long...and then more ads! Very frustrating.

Great heart rate monitor, but ads a little much

The actual heat rate monitor is great. Sensitive, accurate and giving a pulse wave. Because of the wave you can even use it to see heart beat regularity which is great for several heart conditions.

I expect a free app to be ad supported. Ad support is a continuum from barely even noticed and to so intrusive that it interferes with the ability to use the app. I think this app could benefit from scaling back ads just a bit so it doesn't interfere so much. Especially with a heart rate, I want to get a measurement right when I start the app. By the time you get through ads to the measurement screen here it can effect the reading.
