Caution folks

This app does one thing well, measures the rate at which your heart beats. Even though it has a animation on the screen that some may think is their "rhythm" it can't do that. You have to have ekg leads and a machine attached to those leads in order to know the electrical activity of your heart. I worry about those that may have chest pain and use this app to see if you are having a heart attack, it will not nor can it ever tell you that. If you are having chest pain, jaw pain, arm (esp left) pain, in women back pain as well. Did you just break out in a sweat? Are you pale and clammy? Call 911, time equals muscle when it comes to a heart attack. A paramedic can bring a whole lot of help to you, rather than you driving to the er looking for the same help. Didn't mean to lecture but I don't want anyone mislead and delay treatment. Take care everyone, yes I am a medic and use this great app just to record trends in my own heart rate. Nothing more nothing less.

Excellent and Accurate

I came to this app after reading an article about the inaccuracy of wrist band heart monitors. The article compared readings from the wrist band monitors to an EKG machine and mentioned that chest strap heart monitors are as accurate as EKG machines. So I’ve tested this app and Cardiio’s similar app. Both apps are as accurate my Polar chest strap heart monitor. I’m super impressed by both apps and they both link with Health Kit. I have to say that I love my phone. Calling it a phone or even a smart phone doesn’t quite seem right. I use it to monitor my heart, record my blood pressure, record how many calories I’ve eaten and burned. I use it as a camera, to check weather, listen to audiobooks and music. I use it as an alarm clock, stopwatch, and timer. I think the thing I do least is actually make phone calls.

Amazingly accurate. Improved, but still frustratingly sensitive to finger position.

As a concept, I've loved this app since it was released. I give it five stars for pioneering, or better put, translating a science from the medical arena to a user-friendly, handheld product.

My gripe, which was so extreme with earlier updates that I'm surprised I never deleted the app, is that finger positioning over the cam (along with light saturation) is simply too cumbersome for casual users. On the older version, when I handed my phone to my dad to try, not once could his fingers get it quite right.

This version is 5x better, but it still needs improvement. How that can be done, I do not know. I fully support the team behind this, though, and know they're dedicated to constant innovation.
