Dont bother with Pro
As an online dictionary and translator, this is fine. But pay $3.99 for the "offline" mode, and try to get anything useful out of it. Very limited functionality, as I was unable to find any translations that actually helped unless I was online. The Pro functionality is advertised as much more than it really is, just stay away from it.
