The amount of apps downloaded has continued to increase from year to year and most of the apps downloaded are free. Research by Gartner point out that the percent of free apps out of all downloads is going to increase at least by 3 more percent by 2016. Even the paid apps that are downloaded are in the 99 cent to $2.99 price range. Advertising and in-app purchases will become the source of income from apps since downloads will be often free. New app stores continue to open, but Apple still holds fourth of the all the available apps in their store.
