Worth it for BBC Music Magazine, Time & The Atlantic here, cheaper than subscribing to each individually. I’ve wound up blocking certain publications from appearing in my feed - I really don’t need gossip about WAGs, manufactured outrage over TV quiz show contestants from The Sun, The Mirror etc on my phone.
The app is far from perfect, and the PDF based periodicals are useless on all but an iPad. If you put the time into curating what you do and do not want to appear in your feed, would regularly pick up at least a couple of the magazine/periodicals and either don’t mind panning around or using an iPad for the PDFs/unformatted for smaller screens, it’s worth it.
From a purely news based perspective, you might well be better off with a digital subscription to a daily newspaper. I have seperate digital subscription to The Times & The Guardian and even though both allow some of their content on News+, there is no comparison in terms of how comprehensive the quantity and depth of content in the two direct digital subscriptions to the same titles content on News+.
if you’re on EE here in UK, you can get a free 6 month trial of News+
