The change comes two days after Twitter announced its second-quarter earnings, revealing that user growth is still sluggish despite the additions meant to make the service more friendly, like adding Moments and a different timeline. Shifting the category might juice its slowly growing user base. In the first quarter Twitter added just five million new users, bringing it to 310 million active monthly users. Facebook has 1.65 billion monthly active users.
Twitter is still listed under the Social Networking category on Google Play.
