Pushing collective total to 13.7 billion.
ABI Research reckons games, digital publishing, social networking and m-commerce are the four key tablet app platforms, and that they will account for 11 billion downloads across iPad and Android.
Mark Beccue, senior analyst, said: "Media tablet app consumption will mimic smartphone app use in some ways, but in many ways, it will be very different."
Children and seniors are expected to fill in the gaps for the tablet market, with almost one billion apps designed for kids will be downloaded in 2016.
Beccue continued: "The magic of media tablets for seniors and children is the touch screen interface. It's so intuitive. These demographic groups will rely heavily on downloaded apps over web surfing on their media tablets."
