Is my Iphone getting hacked?

Hi, while I was on an app on my iPhone 6 (IOS 8.3) this pop out came on the screen, i had this reflex and just tapped the screen without fully reading what's on it It dawned to me that the pop out was a little bit weird, I think i read the word (Sophie?) put in mind that I don't know anyone buy that name nor have i downloaded an app that has Sophie in it.

I haven't found any weird apps installed or anything

Added (1). what is that? By the way my phone isn't jail broken.

Definitely… The Soph.rs version of Bosspy.
