Books into Apps – An Author’s Perspective

Many people in the world of children’s literature are curious about how books are converted into apps. I’m a children’s picture book author/illustrator with two apps out in 2011, so here’s my experience with the process.

Fifteen months ago I was approached by Omar Curiere of OCG Studios in The Netherlands. He had sent me a “fan” letter about my maze books a few years ago on behalf of his then five-year-old son. Now he wanted to make apps, and thought some of my work would lend itself well. I was delighted.

“Roxie’s a-MAZE-ing Vacation Adventure” is an interactive animated (sounds, moving parts, etc) game app for the iPad, iPhone, and iTouch.  It isn’t a direct book-to-app conversion, but is based upon my five published maze books. We decided that I should do new work for it. I designed a maze game, and made a quick three-day trip to Holland to discuss technical and creative issues (didn’t really have to go; it could have all been done via email).

I created a giant (42”x60”) maze, and almost 400 spot illustrations to animate. It took three months to execute the detailed and complex maze, and another month to do the spots. Two OCG Studios employees spent three more months making the app. Special music was commissioned over there. The app was extensively tested, including a session with 150 students at a local elementary school. Much more than an enhanced e-book, it’s an interactive game – a random maze, with animations, sounds, and items to find.

“Roxie’s Doors,” for the iPad, is a direct book-to-app (3-D, animated, with voice-over, sounds, and many things to search for). When the rights to my lift-the-flap book, “Doors” (Chronicle, 2004), reverted to me two years ago, I also requested the art scans (authors: do this as soon as your book goes OOP). So I was able to transfer large high quality digital files via email to the developers. They spent three months creating the app. I illustrated more spots to animate, and did the voice-over in a studio here in New York (you can also choose a male reader, or read it yourself).

We hired a graduate student for six months to do marketing (very important!). Regular book review venues are not always helpful with apps. You have to reach individual parents, and the audience is worldwide. The maze apps sell in 64 countries (no language issue) and the Doors app, which is in English, sells in 24 countries.

We received great reviews: Kirkus, SLJ, Horn Book, PW, Common Sense Media, a Moms With Apps 5-stars (rarely bestowed), and raves from Teachers With Apps. Perhaps most gratifying were a couple letters recently from mothers with special needs children, who become engrossed in opening and finding things, and, as one mom said, boys need non-violent intelligent apps.

The important thing, always, is to think of your audience… those who seek out and engage in the creative product. Some books are not particularly appropriate for development as an app, as wonderful as they may be in print.

    Love seeing you working on the maze. Interesting information on the blurring lines between books and other media. Thanks!

  2. Denise fleming

    Thanks for the info. I have to say I find all the new technology a bit overwhelming. Your article answered some questions I’ve had. I also loved the photo of you “getting into” your work. Thanks.

    Apps are great, but for anyone who hasn’t seen Roxie’s drawings, take a look — they are terrific, the way children’s book USED TO be illustrated back in the old old days. They just make you feel good just looking at them. You want to shout ” Hooray.”

      Gee, thanks, Ford! Very encouraging…gives me the CTGO (“courage to go on”).

    Roxie’s drawing are terrific.

    (hope I can post this this time)

  5. Karen Robertson

    Both of Roxie’s apps are beautiful. Thanks for sharing your story!

    Thanks, Roxie, for your descriptions of creating for this new technology. I wil add your Doors to my list of apps for children with special needs.
