What apps would I use to edit picture like this?

To add like glow effects to picture or to make picture look cartoonish like. Or where you can like change the colors in the pictures. Like the ones in this link. I have an iPhone so it has to be an Apple app. And if it isn't an app what kind of software is it?

An "app" is an application. And these are pretty bad edits, so.

But you could use lightroom. But then again, you probably won't so just instagram it or something.
