Probably not too comfortable, but this is the conclusion has come to after analysing approximately 65,000 of the more popular apps in the Apple App Store.

The months-long Bitdefender study found that some 41.4 per cent of the apps analysed can track a user's location.

"This means that that most iPhone owners are likely to have at least one app on their device capable of knowing where they are," Bitdefender's chief security researcher, Catalin Cosoi, said.

The other revelation was that only 57.5 per cent of apps encrypt stored data while the rest do not.

"With more than one in three apps storing your data without encrypting it, this potentially places the user's data at risk after accessing it," Cosoi said.
