Worked until I went back to default launcher the error message "Screen overlay detected". What ever that is. Google play only presents apps when that is googled. Went to permissions and turned off all apps that can be on top and still could not assign permission to O2 monitor. Off buttons would not turn on. Therefore the app I paid for is not usable because none of the screen instructions work.
Gives perfect results even against a wall
Very cool app. Even works on my LG Stylo 3 Plus. Very useful to have.
Would like more information on the emotional part and how it determines the data.
Brilliant app used twice daily and very accurate in reference to paramedics equipment would highly recommend this app specially if you have health problems and need to monitor your vitals regularly.
