The app works as stated. It will shorten URLs.

However, it states that one can use a number of URL shortening sites, though, but it only uses TinyUrl. One would assume that going into the settings would allow one to change to bit.ly if desired. The only thing that one can do in the settings is enable or disable notifications.

I tried adding another app (this one actually) to the one that I was already using to unlock premium features and see if that worked. It says I have premium features installed but nothing shows up.

Interestingly, the oinkandstuff products seem to exist to be somewhat helpful and to advertise their own products.
