In my experience, it's extremely basic. Yes, it can rename a function or variable, but that doesn't compare to AppCode.
AppCode can do both of those. Want to add a new parameter to a function? AppCode can do that, and put in a default value for you everywhere. Signature modifications are a snap. Plus it searches for possible references to the function you're modifying and can suggest fixes for them too. That alone is with the $99.
