Just what the Doctor Ordered

I have several extremely rare autoimmune diseases and Dysautonomia is a constant this app provides me a journal of sorts to keep my data all in one place.

Just place your finger on the camera lens and you get a heart rate reading.

Daily 02 not updated

I wish I hadn’t bought the year subscription which I have now cancelled. This app does not keep the daily 02 updated sometimes not until late in the day. I’ve found other .99 apps that are much better!!!!
