Trouble in iPhone land

Since I tried taking my blood pressure the app hangs after launching and will not work.
Also the download screens should not say bluetooth is off but instead that a connection hasnt been established. I noticed this first with downloading from my watch.
Also I understand iPhone bluetooth has to be on to download data, but why does it have to be on just to lauch the app?

Bigger concern, the iPhones Health app/dashboard is not receiving all data from iHealth or iGluco apps. I even noticed flights climbed not registering in Health dashboard without powering off and on the iPhone. Thank you, especially if you can fix all of this.
