Very Inaccurate

I have tried this two times for weeks at a time. I’m permanently deleting it as it’s very inaccurate.

I use another app to monitor as well as using an iHealth blood pressure monitor. I have used this app in between the other two less than a minute apart. The other two almost always give a reading of 60 (which is what I expect since my pacemaker is set at 60). This app nearly always gives a reading of 74 or 75. I have also tried at doctor or cardiologist appointments with the same results. Obviously this app is far from accurate. I don’t recommend it at all. I’m sticking with Heart Rate (blue and white circle around a black area with an 85 in it) as it matches doctors, my blood pressure monitor, my pulse I take manually and my pacemaker settings.

Really good simple app.

My doctor was was worried about my heart rate being too high so I've been checking it to make sure it's not too high and I need to go to the hospital.
