Clueful, from antivirus experts Bitdefender, is a great little app for iOS that tells you which of your apps are accessing your personal data, and exactly what data they may be interested in. We wrote about it back in May when it first hit the App Store, and I liked it so much that I included it in one of my must-have apps roundups.

But it seems Apple wasn’t so keen, because it has now yanked Clueful from the App Store, and no one knows why.

Kicking off this week’s must-have apps roundup is a new web browser from Yahoo! called Axis, which hopes to redefine web searching on desktops and iOS devices. We’ve also got a terrific app for web editors, one that’ll help you monitor which apps are accessing your personal data, and two new apps from Facebook.

There has recently been a lot of concern into the way in which our iOS apps access our personal data, and then what they do with it once it has been collected. Since the whole Path debacle in particular, users seem to be more concerned by the issue than ever before.

BitDefender is one security firm looking to capitalize upon that concern with a new app called Clueful, which promises reveal what each of your apps is doing with your data and identify the “misdemeanant apps on your iPhone.”
