What app was used to edit this picture?

I have an iPhone 5 and I wanna know what app was used to edit this picture and make the lines in the picture! Help help help I've looked endlessly and can't find it

I don't think the lines were added to the image using an app, they were done most likely on a PC using Photoshop or some photo editing program like that.
