Use of mobile apps has grown to where they're now overtaking the web as the preferred format on phones, Flurry said in a new study on Monday. Where the web was still the most used in a given day a year ago at 64 minutes per day versus 43, the situation has now reversed. As of this month, phone owners spend about 81 minutes in apps per day and an increased but still lower 74 minutes on the web, marking the first time the web wasn't the main avenue.
