One "free" flashlight app in particular was targeted by the FCC. "Brightest Flashlight" was an unassuming little flashlight app which shared its users geolocation information with advertisers.
The FCC takedown wasn't the only attention that Brightest Flashlight received, either.
Researchers compared the top 100 apps on the Google Play store and found that many of them ask for your location information, contact lists and identifying details about your gadget.
Though the researchers looked at Android apps, almost all of these apps have iOS versions.
