Children’s apps publisher Night & Day Studios has released three new apps based on its licensing partnerships with Warner Bros and DC Comics, under the banner ‘Stickers with Sounds’.

The apps – DC Super Friends: Stickers with Sounds, Batman: Stickers with Sounds and Superman: Stickers with Sounds – have gone on sale for iPad at $0.99 each, although that introductory offer will revert to $4.99 after the first week.

All three apps involve children choosing themed backgrounds then pasting on digital stickers of superheroes and villains, with sound and animation to ensure the experience isn’t flat.

The releases come shortly after Night & Day announced a partnership with book-apps company ScrollMotion, whose licensing deals were critical to the Stickers with Sounds apps.
