For its study, Localytics looked at thousands of apps across every major mobile platform using its app analytics software. Worse still, the company found that one-time app usage was slowly on the rise throughout 2010 -- in the first quarter it was around 22%, but by the end of the year it grew to 28%. Suggest VentureBeat: "The increase is most likely due to more consumers getting smartphones throughout the year, and we can expect the number to grow even further over the next few years." One reason for app's relative popularity is their simple adoption requirement. Generally, users only need to locate the program they want in an app store, choose to download it, and wait while their device works its magic.
