Poor signal
TropicRanch
There’s often a poor signal or other reason it doesn’t work. There’s not much else useful about the app, sorry I paid for it!
Does not work with multi-lens iPhones.

It is very disappointing that you did not update the software to use the lens closest to the flashlight for multi-lens iPhones. It used to work great with my single-lens iPhone (we even purchased the in-app upgrade), but now, with my multi-lens iPhone 11 Pro, the app is useless crap! The light and the lens are too far away from each other to get an accurate measurement! The iPhone 11 Pro was released 1.5 years ago (that's when I bought it)! How much more time do you need to fix the problem ??????)
Pricing question.

Cannot find info for any "subscription pricing or free trial period displayed in the app" as stated in CARDIO terms of service.
SVT Recording

App is helping me record incidents of SVT. I’m on a heart monitor now, but this app gave a picture of what is going on. It’s not “official” but still a good picture.
A fib

This app helped me when I had afib, to track my rate. I have now been shocked back to a “normal” rate and can now monitor to assure I’m doing ok. Thanks
Better Than The Other Semi-Free Apps

I downloaded about 7 different heart monitor/pulse checker apps on my phone. I uninstalled every other heart monitor except for this one. You'll understand what the differences are too...
It worked well until iPhone 11 Pro

Per other reviews, this app does not work with the iPhone 11 Pro. Such a waste.
Workouts

Good App. I enjoy this app with workouts. Download if you don’t have program to do workouts.
