Update 2-20-22: Still needs a clear exit switch at the top level-minus 1 star. Minus one star for not knowing Android One/Nokia GUI's don't HAVE a square button in AOS 11! Minus one star for snarky "Don't like ads?" (No, man, I want more, gimme more!) marketing prod. Minus one MORE star for having the app still running in background even after you've hit "exit" in "profile" section, which they say will completely exit the app. Bad misrepresentation. Still not fixed a/o update.More frequent ads!
