I've been using iPhoto on my iPad for a while to retouch photos. I know this will have many of you in shock, but I prefer any enhancements to be minimal so this does the job and allows me to do it while on the road. The one thing I can't do natively though is Geotag, even with the new version which came out today. iPhoto still only lets you modify geotag info, not add it when it's previously non-existent.

I'm wondering if anyone has any recommendations for iPad apps that are light, simple, and allow you to select a large number of photos and add geotag info. There's quite a few out there, but I'm hoping people here may have experience with some already to give a recommendation.
