Google Maps is the most used smartphone app in the world. According to data published by GlobalWebIndex, 54 percent of global smartphone owners used Google's navigation app in the month preceding the survey. Facebook's smartphone app ranks second with 44% of smartphone owners using it. The fact that YouTube and Google+ are ranked third and fourth shows Google's dominant role in the mobile marketplace: three of the four most used smartphone apps in the world are Google apps.
Google's decision to develop an open source mobile operating system and give it away for free apparently pays off. Android's market share in the smartphone market recently soared above 70 percent and since Android phones come preloaded with several Google apps, the search company controls a significant share of mobile web usage.
