Works offline. Gives lots of conjugations. I have the paid upgrade. – Spanish Dictionary + © Review

Pro: Works off line. I can look up a conjugated form and it takes me back to the root verb. Faster than the other dictionary I use. Also gives English conjugations. Con: Doesn't conjugate the imperative. I am not very advanced in my learning but even so fairly often I find myself wanting words that aren't here.
