Apple won't approve iOS anti-virus apps, but that doesn't mean there aren't security issues for the platform that can be addressed. BitDefender's Clueful analyses the impact of other apps you have installed on your iPhone or apps you're considering installing, including what data they share, whether they use excessive battery life and how they store data.
Clueful can also inform you which apps track your location, whether they access your Facebook or Twitter accounts, and which ad networks they use. This is familiar information for Android users, who get told about these permissions before installing. It's always a sensible idea to check these kinds of details so you understand what your apps are doing, and Clueful simplifies that task for iOS owners.
Clueful is a $4.49 download for all iOS devices. If you give it a try, tell us how it goes in the comments.
