The iPad App Store has been updated, and has added the ability to sort by the Release Date for apps. This is a small but very cool addition – as it makes it much easier to see new apps as they come in – although it’s brand new so I’m not sure how often it gets updated (hopefully daily or more).
To see apps sorted by release date, go to the Features section of the App Store and you’ll see it as the third tab on the right at the top of the screen (alongside New and What’s Hot).
Update: As Andrew has kindly pointed out in the comments, you can also sort by release date within categories. It is the second tab at the top of the screen within category sections. Very cool.
