Ozone also includes a standalone app that you can run your stereo mix through independent of the DAW. Also Ozone 6 (my product) has a suite of "light" presets and they will not "suck the life out of your" as somebody mentioned. The other presets can indeed do that unless you modify them per your song.

It may have been mentioned but I suggest you resist the temptation to use Ozone for mastering at any point during your production until you are satisfied with your mix.

A great companion to Ozone is Izotope's Nectar which is for vocal processing but has an incredible reverb that can be used alone for non-vocal tracks.
