I haven’t been able to verify if heart waves are accurate yet. The rate seems close to my Fitbit reading which I have verified as accurate. I can’t say anything about the calendar function or anything else yet since the app requires a 5star review in order to access the calendar. For a free app it seems good so far.

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.

Warning everyone. This app says that u have to rate it 5 stars to be able to unlock past heart rate feature so they can make the app better. Not very good and honest business to bribe people to give top rating just to unlock to use. This app is by far not a 5 star but it’s decent.
