We were pretty impressed with iPhoto when we tried it out, and the app seems to be gaining strong traction with iOS users, as well: Apple told The Loop that iPhoto for iOS hit one million users in less than 10 days. The app was released on March 7th, so that would mean it hit one million users sometime around last Friday, when Apple also introduced its latest iPad. Unfortunately, it doesn't look like Apple has made any public statements about how many users its other iLife and iWork apps sold in the weeks immediately following launch, but iPhoto currently sits at number three on Apple's list of top paid iOS apps — right behind Draw Something and, naturally, Angry Birds Space.
