Simple to use accurate

Simpler to use and is accurate!! I've been in and out of the hospital a lot recently and have needed to monitor my heart rate and blood pressure. A nurse told me to download this app to keep track of my heart rate and O2 sat at home. I've felt comfortable using it. I used it while in the hospital to check the accuracy against the hospitals and the measurements always were within a few numbers of each other. I am in no way saying that this app should replace any actual medical equipment or medical advice but when that is not immediately available, it is nice to have something to go on. Like if you need to keep a record to take with you when you see the doctor next or if you feel something is off you can use this to check and if the numbers indicate a problem, seek the real deal medical doctors! Love the app!!! Good stuff!!!

Simple and Accurate

It works, plain and simple. If you take a reading it automatically stores it in the Apple Health app for tracking. With my heart rate chest strap on it is always within a beat/min of the chest strap. Would be a real PITA to use during exercise as you have to cover the camera and flash with your finger and be pretty still to take a reading. I only use the free feature so can't speak of what you get if you upgrade.

Great App!!

I have a condition where my heart beats extremely fast and this app has helped me be able to keep track of my heart rate. I have used it and compared it to the rate on on EKG's and pulse ox's and manual calculations and it has been exact. You do have to wait until you get a uniformed wave length and then let it take for the ten seconds for it to be accurate but that's the way the pulse ox and EKG's are too. Thanks for making such a great app!!
