iPhoto for iPhone and iPad
Jim Dalrymple noted that Apple specified it was counting users, as opposed to downloads, which means that downloads to multiple devices by one user weren’t counted.
iPhoto is Apple’s photo management and editing solution. It was originally developed for the Mac as part of the original iLife suite, and it’s the fourth member of that suite to be brought to iPhone and iPad.
iPhoto for iOS is priced at US$4.99.
