Sure Pixelmater can too and iDraw also has great options for getting down with your pixel loving self, but after a few short minutes I can recommend you take a look at Affinity it looks like a doozy and at a reasonably price.
The toolset really looks like it might facilitate some really great art via new workflow paridigm, as always, that will be decide by the artists.
Right now you can get in on the public beta and try it for yourself, so why wouldn't you?
