A new report from Comscore finds that smartphone owners use apps to access the Web 81.5 percent of the time, while they rely on browsers just 18.5 percent of the time. For some sites, including Twitter, Amazon, eBay, Zynga and others, the percentage of time smartphone users spend with apps as opposed to browsers is even higher. On the other hand, smartphone owners continue to rely primarily on their browsers to access ESPN, Microsoft and Wikimedia sites.
In separate news, a new Nielsen report finds that more than half of all U.S. mobile phone subscribers now have smartphones. Android continues to be the most popular smartphone OS, but Apple is the most popular manufacturer.
