Because it wasn't obvious to me for a while: the Play store version is old, basically broken, and vulnerable [0]. Don't install it. The description does mention this relatively high up, but do you really read through the description for something before installing and playing around with it, especially if you already know what it is?

I don't usually like having old versions of software removed from distribution, but maybe in this case it should be removed from the play store since it's basically useless and also vulnerable.
