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 👍

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. ❤️😎

Was Great

I first downloaded well let me say I purchased Azumio Heart Rate Checker when that was all you had to pay for; just the app. Of course they had a free version but I opted for the paid version because it had more features. Now this app has turned into one big in-app-purchase. Everything you click on; in an app you already paid for, opens up another screen wanting you to sign up for a premium subscription. There are thousands of similar free apps on the app store that offer the same services as this one but again I went with Azumio. Now I wish I would have never even downloaded this. Yes it will check my heart rate but then it jumps to screens you can’t even view unless you buy a subscription. I wanted this app because I have high blood pressure and have suffered numerous heart attacks and needed something to keep track of my heart rate. I don’t care about my weight nor do I care what Joe Blows heart rate is in another country. This use to be a straight forward heart rate monitor/tracker and greed has driven the developers away from what once made them great. If I was an athlete, weight lifter, or health nut then everything in the app would be fine. But not everyone is wanting everything thats offered in this app yet it’s constantly threw down their throat. I still monitor my heart rate and will do the Stand Up Test but then I close the app out just to forgo all the subscription pop ups. Sorry Azumio but this app just isn’t what it use to be.

Great app, with a few disappointments

Love the free app! User-friendly interface, great decisions on what to emphasize—e.g., including a prominent step tracker. One suggestion I have for the free app would be to tweak it so that your flashlight doesn’t come on as soon as you open the app. One more prompt before turning it on would be great.

My major disappointment was that after I paid for the app’s “insights,” it proved to be really just a summary/snapshot of your data, which you can already see for yourself within the free app. I thought it might be more involved, I.e., offering suggestions for lowering your restrictions by heart rate, etc. Please improve these “insights” we’re paying for!
