I have long been looking for a product like yours.

I have actually posted my wish list for a mobile version of Aperture on my blog a while back.

I am not sure if your product syncs with Aperture like what I am looking for.

Also, it appears that you need to import (duplicate) the iOS photo library into your own application. If this is the case, then you would be using valuable memory space on my iPad, even more so considering that I shoot RAW.

Please let me know, I can wait to find out more :)
