Hi! My doctor prescribed a home sleep test by Virtuous. It is managed by a phone app like SaA Its a band that I tape to a finger. My question is, should I run both app simultaneously? If not, is there a way to pause SaA? The only choice in Settings is to uninstall; the force stop is grayed out. If I have to uninstall, will I have to set the app up from scratch? Thanks!
