Read full description

Karnal is a series of next-generation educational materials designed for both academic educators and self-taught readers interested in the visual arts. The book, Colorimetry, features a distinctive design that moves away from the traditional textbook format. Its graphics are integrated as background illustrations, while the text exists on a separate reading layer. The book’s content is presented in articles. By accessing the built-in cameras on mobile devices such as smartphones and tablets, our Karnal app recognizes each article and triggers a third layer of reading: an interactive augmented reality experience. Each experience is accompanied by instructions and additional content beyond the printed material, introducing a fourth layer of reading within the app. This layer expands the publication with extra texts available in multiple languages. To enhance usability, our platform can convert printed text into audio through a multilingual synthetic voice, reading it aloud via our text-to-voice system.

The official Dr. Seuss learning app for ages 2 to 8. 100+ learning games inspired by 22 books, no ads, no behavioral tracking, and one price for up to 4 kids. Remember your first Dr. Seuss book? The Fish that was red, the Fish that was blue, the Fox in the socks, and Horton heard a Who. The rhythms and rhymes that stuck in time, repeating in the back of your head. Some things stick with you. 80 years. 800 million books. Generations of kids falling in love with reading. Dr. Seuss: Learn & Play is the official Dr. Seuss app made for learning, with the real characters, the real art, and the stories you grew up with. Letters with the Cat in the Hat. Counting with the Lorax. Kindness with the Grinch. Reading, counting, music, art, and problem-solving, all woven into the stories you already love. Every game has an ending, the way a book does, so there's always a natural place to stop. Each child finds their favorites. And you'll see it working. Every week, a simple report shows you what's taking hold: the letters they can now recognize, the words they're starting to read on their own. Real progress, week by week. Here's what we won't do: • No ads to keep playing • No behavioral tracking. We collect two things about a child: a nickname and an optional age range • No selling kids' data to advertisers • No coins, gems, or gold stars to grind • No streaks to keep, break, or feel guilty about • No timers ticking down the fun • No character guilt trips into playing one more time • No locking the fun. A child never begs you to pay • No cancellation maze. The cancel button is 3 taps away Here's what you get: • 100+ learning games and 1000+ activities: letter tracing, puzzles, building, matching, music, and rhyming, with new games added regularly • Every game mapped to a named skill and a CDC developmental milestone before it was built • Works offline. Airplanes. Backseats. Doctor's offices. Wherever you end up. • Up to 4 kids on one subscription, each with their own profile • A weekly report, so you know it's working Designed with Renée Jordan, our lead educator, who holds a Master of Arts in Applied Educational Psychology from Columbia University, so every game is built around a real skill for curious kids ages 2 to 8. The 22 books that inspired the games: The Cat in the Hat, Green Eggs and Ham, One Fish Two Fish Red Fish Blue Fish, Fox in Socks, Hop On Pop, Dr. Seuss's ABC, The Lorax, Horton Hears a Who!, How the Grinch Stole Christmas!, Oh, the Places You'll Go!, Oh, the Thinks You Can Think!, The Sneetches and Other Stories, Yertle the Turtle and Other Stories, Mr. Brown Can Moo!
