Yesterday we released ’3D Bookshelf – Robin Hood Edition’ for iPhone & iPod touch. The app is completely free and we’re eager to see if it affects sales of the premium version ’3D Bookshelf – Classic Literature Collection’ in a measureable way.

It’s only been 24 hours since it appeared on the App Store and it’s already shot up the Free Book Charts in 23 countries. We weren’t expecting to see it rise quite so quickly. If you’re interested in seeing the app or getting in the mood for the new Robin Hood movie, download the app and let us know what you think.

For now, it’s back to our latest creation. We’re progressing well, but there’s still lots to be done. For updates, you can follow us on twitter or subscribe to our mailing list.
