In a piece of news, it's said that "twice as many smartphone users access news primarily through browsers rather than apps". I'm not clear about the expression "twice as many" here when there is nothing to compare with. If "I have twice as many books as he has", I can catch it. But here twice as many smartphone users as what? Could you help explain it to me? Thanks a lot.
It is a comparison of those smartphone users who use a browser versus an app.
If 100 users use an app to read news, then 200 use their browser to read news.
