Why would this app start with a sign-in screen? The information it provides to the user does not depend on who that user is. Are they trying to track me? I just choose “guest,” but that is still an extra click before I see what I came for.

Also, the text of that sign-in page overflows to both the left and right sides of my small screen, so you can tell they just tested the app on more capable hardware. Other than those complaints, it performs as advertised.
