As others pointed out doesn’t work well with iPhone 11pro. Hard to get refund. Do not recommend purchase.

I have a fib and have been living with it for years this is a fabulous tool to keep track of my pulse rate which since I have a fib fluctuates greatly

I used to love this app because it would use the front-facing camera to look at your face and detect your heart rate. It seemed like magic, but it was based on cutting-edge research, and that’s why I bought the app. Unfortunately a recent update removed this functionality, making it just like all of the other ‘put your finger over the camera & flash’ apps that have been in the store for over a decade.
