There is a bug, I just haven't found it yet.
Well, it's broken on my machine!
In the Danish version of Windows, if you click really fast, the app just crashes.
It doesn't work when I put Cyrillic text in. Or Greek, Hebrew, or Mandarin.
One copy of "War and Peace" in the description field was OK, but the second crashed it.
What if you rotate the screen/turn on airplane mode/get a text/drop the phone into the toilet from ten feet up?
The app doesn't handle itself well if you delete its database after you log in.
Ooh, I haven't seen it do that before! Wonder if it'll do it again?
Can't stop, I saw a bug and I'm trying to find it again.
(From a QA friend) There you are, you little sh*t! I have you now!
