Sony has the worst app I’ve ever seen[1], to the point where I legitimately don’t know how it passed the app store vetting process. Paragraphs of text have wrapping disabled so that the text goes off screen (important text, like the TOS!). Text which does have wrapping enabled wraps on character boundaries instead of word boundaries. Bullet-point lists don’t line up. I have no idea how they made it so bad, it feels like it must’ve taken effort to disable things which just work by default?
It also has two buttons. I really don't see the need for an app. Besides that I don't have a phone capable of running an app so that saves me from getting irritated at Sony. Again.
