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, tedwang asks:

I'm kind of shocked I haven't found an app that can add captions to photos. Actually I'm surprised that Apple's own photo app doesn't do this. I don't mean a caption ON the photo -- more in the metadata. This is so I can keep track of what I'm taking a photo of. And I don't want to have to share it on Facebook or Twitter to caption the photo.

What tedwang is specifically looking for, is a way to edit the IPTC info on a photo. To see what we found for him, follow along after the break!

One of the many features of Photogene² [$0.99 - App Store link] is to edit the IPTC data on photos.

IPTC stands for International Press Telecommunications Council and was originally developed for media to quickly exchange information about news items like photos. Some of the info that can be stored in the IPTC is author information, title, caption, and copyright.

Photogene² makes editing this info a breeze. With an upgrade to Pro, you can even create IPTC sets to streamline the process.

Anyone else have any App for That suggestions for tedwang? Let him -- and all of us -- know.
