I’m now getting poor connection issues most of the time and can’t get a reading at all. I do have the newer iPhone SE so maybe it doesn’t as work as well with it.

Great way to monitor heart rate if helped me make the decision to see a Dr about it and found out I was Tachycardic and get it treated . !

Doesn’t work that great on a high heart rate when you have been working out tries to cut heart rate into. When I work out My heart rate is between 120 & 130 this app doesn’t record it 75% of time if it does get it it drops out at the end.

Cardio isn’t as good as a medical pulse instrument, but it works well enough for me to determine whether my supraventricular tachycardia (SVT) is acting up. I ignore the pulse height and shape, which vary randomly if I don’t hold my finger steady enough, and pay attention to the pulse spacing. Cardio works better for me than holding my finger on a blood vessel. My SVT is mainly an annoyance; I am not recommending Cardio for more serious arrhythmia. Follow your cardiologist’s guidance.

This app is very useful while taking a jog, for giving me an indication for when I need to take a break and when to restart. However, half of the readings end with the poor signal quality pop-up, which prevents saving of the result. By then my heart rate is too low to take another reading and save it.

Wake up people. Are free apps worth your privacy? Read the terms of what and whom the share your private health data with. Do you want it shared with facebook health groups. Not worth it. Buy a heart rate monitor or spo that doesnt do this
