* Instant Heart Rate detects a color change in your finger tip each time your heart beats and uses an advanced algorithm to show you your heart rate.

* A real-time chart will show you every heartbeat, similar to pulse oximeters used in hospitals.


Instant Heart Rate saves lives:

“On Sunday night, I was experiencing some unusual feelings. I knew that my body didn’t feel quite right. Quickly, I found out that I was in AFib with a heart rate of 193. I am writing this email from my hospital bed. I want to thank you for being an instrument in saving my life, literally.”

Excellent app

This little app does exactly what it's supposed to - nothing more, nothing less. It avoids the flaffing around finding your pulse then counting while keeping an eye on the second hand of your watch or clock.

Reasonable app

Not a bad app that actually works but not sure how accurate it is.
Down side is that it is riddled with adverts and upgrade requests that make it very annoying to use.
There may be something better out there but I haven't looked yet.

Doesn't work on 6s Plus

I used this app a lot, but since I've upgraded to the iPhone 6s Plus it doesn't work. I'm guessing it's because of the distance between the LED light and the camera lens on the new phone.
Unfortunately I've had to remove the app.
