From a sample of 100,000 iPhone users worldwide over 90 days, software company Onava has a compiled a list of apps used most on the iPhone, and analyzed how much monthly data each consumes on average.
Onava offers apps that allow iOS and Android users to monitor app and data use. The list excludes games, native apps, and those that do not nibble away at subscribers' wireless data plans. The omission of the built-in apps including YouTube and Google Maps apps could disrupt the list a bit, but the insight is still valuable.
It is not much of a surprise that Facebook tops the list for popularity with WhatApp and Twitter trailing in the distance.
Skype's appetite for bandwidth made it the app that used the most data chewing through 14MB per month on average. Photo sharing app Instagram followed at 9.4MB per month and Facebook with 9MB per month.
