I don’t see any value out of those basic HRV readings directly from HealthKit, and blood pressure by manually logging them? It is merely better than a paper notebook. So far too many white label apps doing the same things, with this one being one of them, pattern is: all released under an individual developer who has only one app; all with a name stuffed with keywords; all forcing to purchase at the end of the instruction; all without a working support website; so much so confirms this is a white label app. This is unfortunately, an app released by an app farm organization trying to flood the App Store for profit, with 0 intention to help with users health.
