Last week, internal documents revealed that Microsoft had offered to buy Nook Media from Barnes & Noble for $1 billion. Those same documents also revealed that Nook Media would start to focus more on its software app on other platforms instead of its own hardware. The first step to improving its apps may have come today with the latest update for iOS.

Barnes & Noble announced a newly updated Nook app for iOS that allows customers to purchase and read comics on their iOS device. It’s a nice alternative for iOS device owners who may have found Comixology or the dedicated Marvel app lacking in options. The wide selection of graphic novels is also a nice bonus.

Alongside the addition of comics, the new Nook for iOS app adds the “Zoom View” feature that allows readers to “focus in on individual panels in graphic novels and comics.” Anybody who has tried to read a comic on a tablet or smartphone before knows how painful it can be sometimes so the addition of this feature is welcome.

Here are the other new features now available on Nook for iOS:

“With our free, updated Nook for iOS application, we’re delivering to customers with iPad, iPhone and iPod Touch a great optimized reading experience, now with access to Nook Comics, one of the leading collections of digital comics and graphic novels available,” said Jamie Iannone, President of Digital Products at Nook Media LLC. “Using their iOS device, customers can enjoy Nook’s collection of more than 3 million digital books, magazines and newspapers, as well comics and graphic novels with the stunning Zoom View feature.”

To celebrate the comic-centric update, Nook will be giving away a free Superman sampler to all those who upgrade their iOS app. The sampler includes excerpts from Superman: Last Son of Krypton, Superman: For Tomorrow, Superman: Earth One, and Justice League Volume 1: Origin. It’s no Free Comic Book Day, but it’s still a nice gesture.
