Useful app

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!

Great app

The ultimate way to check one’s health!

It is so handy to have the cardio app on my phone. So I can keep track of my numbers.

I DID NOT PURCHASE THIS APP. It didn't work as I expected. I looked at it and deleted it immediately, but I'm being charged anyway. I contacted Apple for a refund, but I wanted to let you know. I don't appreciate being charged for something that I immediately deleted, and checked the box on Apple to let them know that I wasn't keeping it. I shouldn't be charged!

Cardio gave me peace of mind Excellent It assist in my keeping my A-fib monitored It has became a very important part to maintain my health. Thanks ever so much
