Have you seen Steepshot yet? That looks like it could be great for Steem too. Unfortunately I can't get it on ios, but android phones can download the app ad use it as a replacement for things like instagram. The only annoying thing is the photo's I have seen so far using this cameraphone app are so much better than mine ;) I guess I had better up my photography game! haha
I've tried it, but I'm more of a writer
