Capital New York: The New York Times is expected to announce in the coming weeks that its NYT Now mobile app will become a free product with a number of changes to its functionality, while the Times’s main news app will introduce a more vibrant look and feel. The Times is revving up its efforts to develop mobile readership and rethinking its second-generation paid-products after last year’s initial push, which resulted in the launch of NYT Now and an opinion app (since shuttered), delivered disappointing results.
