People will die because of this. The app & ads must make pellucidly clear to EVERYONE what it actually does and doesn't do. Instead the devs point out how our understanding of the app is faulty, which completely misses the point: they need to fix the app and its ads. The people who matter are seeing "normal bp" in the app, when in reality they're at extreme risk of a heart attack, and they're not reading the critical reviews here. If they die, their blood will be on the hands of the developers.
