Red dot (circle) next to the app name below the app icon on the iPhone Home Screen on iOS 8

Question

What does the red dot (circle) next to the app name below the app icon mean?

Answer 1

An Orange dot next to an app normally means it's a beta version, as installed through Testflight. I have a couple of those at the moment, though one looks more red. Trying to find if there's a difference between an orange and a red dot, or if it's just an artefact of the colour of the background image that makes it look red.
