The report was based on data from a survey of 1,033 smartphone users in the United States.
Some 37% of respondents select Facebook as one of the three mobile apps they cannot go without.
Gmail is next (34% of respondents say they cannot go without it), followed by Amazon (30%), Google Maps (24%), and Google Search (22%).
Not surprisingly, there is a strong correlation between the apps that rank as the most essential and the apps that are most often positioned on smartphone users' home screens.
