We have been busy working out the systems and working behind this, there are a few fundamental problems like the ratio between screen size and pixel is not fixed. Think of there are 24" screens that deliver 1080p screen resolutions, whilst there also are much bigger screens (>26") that deliver 1080p. We were unable to find a figure in an OS that indicates the size of the screen.
Due to this we haven't been implementing this yet. Whatpulse probably takes a ratio for granted which is average, which could be acceptable but that would be a 'lie'.
