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!

Great health application 👍

Ragnar, American Viking

Been using this application for2-3 years, usually after walking 5-10 miles outdoor , at the gym, after waking up in the morning or just showing to individuals who do not know of the built-in heart application on their iPhone that goes with the heart rate monitor, the free part I like the best because it is simple and easy to use by starting the application and placing your index finger on the lenses of your camera when the light comes on, be patient and leave the finger gently on the lighted area till the circle finishes a full circle and gives you a pulse rate number, there’s a note pad to write what activity you where doing before taking your measurements, Am 64 years old and this tool helps keeping track of my fitness progression in moderation and consistency. ❤️😎

Great App and Accurate HR

Fields of Dreams

I have been using this app for years. I have tested this while sitting and running and compared it to the readings of my chest strap HRM and was happily surprised how well it works, giving me the same rating as my chest strap (which does not connect to my phone). While I don’t use this app to check my heart rate while I run it was still a great test. I have tried other monitors that do not pick up HR very well while running. I purchased the Premium, but have noticed what is included in the Premium keeps changing so its a little confusing when I get ads recommending I upgrade. This is the only thing I don’t like and recommend they re-name these upgrades to avoid confusion or add the new features as free enhancements. Looking at new options they seem appear to be great options.

The med. That challenges the norm.


I have had a really challenging time with medications that like to regulate my immune system for close to 10 yrs now. The latest med. possesses a couple of side effects that lately needs to be moderately monitored to avoid a gotcha situation. This app has been playing a very big roll in making sure that my BP rate does not drop to low. I have been using the app 24/7 now for 3 years and I can say with its simplicity it sure is giving me some pease of mind.
This is truly a great App.
