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!


"Continued use of GPS running in the background can dramatically decrease battery life."

Brilliant- A must have app

This is such a brilliant app everyone should have it! I've been experiencing sudden increase in my heart rate which this app picked up to be 150 plus bpm, having called an ambulance a couple of times and my heart rate dropping by the time they arrived using this showed proof of it happening and showed the paramedics were able to see what had happened, they told me to continue using this so I could show them and the Doctors it wasn't a panic attack as initially thought. Everyone should have this app if medical professionals are asking you to use it it speaks for itself 👍🏻👍🏻

Does what it says on the tin.

I have used a number of these heart rate reading apps and this is one of the better ones, outside of the occasional push to upgrade to features I wouldn't want it is pretty good. If you're looking just to check your heart rate and keep a record of it with tags plus a visual read out of your heartbeat for a few seconds it's definitely worth it. Remember to wipe clean the lens on your phone's camera after using this as often your pictures will look a bit blurry if you don't.

This is my life saver!

I had a major heart attack in July 2014 and ironically enough I was using this app prior to having the attack. And even though the app was showing me my heart was under a lot of stress, I never truly understood the readings. That was until I reviewed them after my heart attack! It was a complete mess. But now nearly 2 years on this app is used on a daily basis and keeps me in check and is spot-on, even my consultant agreed with the readings.
