If he was pushing a random android app on an article that was about a random android phone then you would have a good point. In this case it is more than just tangentially related, the vast majority (read: pretty much all) android phones don't have barometers, this is pretty much the only phone that can even run it. And it also answers the question of "what would I ever do with a barometer on my phone?".
