A new report by Gartner says the number of overall mobile app downloads -- both free and paid -- will rocket to 102 billion by the end of this year, up from 64 billion in 2012.
By 2017, the number of app downloads should reach nearly 269 billion.
Meanwhile, the research firm also forecasts that mobile app revenues will be $26 billion in 2013, up from $18 billion last year. That $26 billion in revenues comes from paid downloads and in-app purchases -- even though only 9% of all downloads this year cost money and the rest are free.
The strongest growth period will be through 2014 when the forecast is that almost 139 billion downloads will be made.
