Another important factor is the price of the smartphones that use each operating system. Currently, the Windows Phone Store offers 150,000 apps ( Figure 4 shows Google apps, Apple apps, and Windows Phone Store apps). According to a recent press release, 775,000 apps are available in Apple’s App Store. In October 2012, Google announced that the total number of apps in its store numbered 700,000. In January 2013, the number of Google Android apps overtook those of Apple iOS-800,000 apps are now available on Google Play.
Surveys using the latest statistics predict that Apple iOS will remain the second biggest platform worldwide, after Google Android (Figure 2 shows this data Figure 3 shows further data), until 2015, when Windows Phone will surpass it. In the Introduction five operating systems were mentioned-Google Android, Windows Phone, Apple iOS, BlackBerry, and Nokia Symbian. We created this list with multiple features and functionalities that we believe has the potential to enhance future MBMAs. features and functionalities were chosen based on the relevant literature, mainly on the study of Klasnja and Pratt, and from a brainstorming and consensus process among all of the authors with two of them (MD and JGC) being experts in and teachers of MBTs.
