I've found an app that's optimised for 6/6 Plus, but doesn't say so

News Republic - updated on 9th Oct, still just says "Optimized for iPhone 5".

Yet when I open it, it does indeed seem to be optimised for my 6 Plus screen.

Perhaps they meant to say 6 instead of 5? Perhaps they simply didn't mention it but did it. Perhaps it's just looks optimized but hasn't been?
