There are hundreds of thousands of iPhone, iPod touch, and iPad apps for just about everything -- so how come the one you need, the one you know just has to be there, is so hard to find? Enter TiPb's new weekly feature where staff and readers alike sort through the App Store and help you find just the right App for That. This week, KP asks:

I sometimes need to take a quick pic and upload it to Facebook but need to blur out some incriminating evidence first (don't ask!!) I know there must be an app that let's me do that but damned if I can find it. Can you recommend something?

To see what we found, follow along after the break!

Hide My Secret! [$0.99 - iTunes link] is a nifty little app that allows you to overlay your images with a pixelated mosaic effect.

Applying the effect is a breeze. Just touch the screen with two fingers and move them around until you have the incriminating area covered as desired (each finger will be a corner of the box). If the area is small, you can zoom in beforehand to guarantee accuracy. You can also pixelate more than one area before saving the image.

Now that you have hidden whatever it is that you want hidden from your photo (we won't ask!), you can safely share the image on the social networking site of your choice!

Anyone else have any App for That suggestions for KP? Let her -- and all of us -- know in the comments.
