Path for Android jumps on the filter bandwagon
Path version 2.1.5 adds what the app calls "Lenses", which are live filters that can be added to photos to give various effects before the pics are shared on the network. The update also adds the ability to delete comments and of course the ever popular bug fixes. The "lenses" are what you'd expect, so if you like that sort of thing it might not be a bad idea to try out Path.
If you want to grab Path, it's available for free in the Google Play Store.
