I found this app is very useful and good one, and it’s free thanx lot for that too

Excellent

Very useful to me this app.

I use everyday to see how much calories i burn during exercise

This is very accurate app I ever used

I thought the technology is a fake. But no. It's really working

Most of the time it is so accurate , 👍

I signed up for a free trial and Apple billed me the very first day

I suffer from A Fib, this app helps me confirm that my heart is not is sinus rhythm. Have just had ablation done to hearts week ago and having palpitations, so want to make sure it’s not A Fib. Appreciate app, would love to be able to purchase it, but on social security there is zero dollars left 2 days after payday.

Signed up for free trial and it did not work on my phone so I cancelled but they had in less than 24 hrs signed me up for the year. Does not work on my Apple 13 mini and my Apple Watch is much easier to use and very accurate. Worthless!
