Good photoshop/ editing apps for iPhone?

I see many people on Instagram. @totheshore, @sailor, @waitingontheworld, @tylermazaheri, @cocainedaisies, @sofiesund, etc.) edit their photos and I really want to know what kind of apps can do that, of it's something done on a computer. The accounts don't like telling people what they use do I'm hoping someone here will help me.

There are dozens of programs where you can apply terrible filters to otherwise uninteresting photos. Like most of the popular photographers use on instagram.

Photoshop makes an iOS app. Snapseed is my favorite iOS editor, and there are lots more. Just search the apple store for photo editors and try out any you think you like.

Agree with Matt- Snapseed is probably the best editor. But you might be wanting more extreme, gimmicky stuff, so just start installing apps and trying them out.
