KnowSoda: General Knowledge

Learn something new every day in just two minutes. KnowSoda is a micro learning app for curious minds: swipe through true or false cards on science, history, psychology, art, technology and much more, learn the key ideas of 150 great books and discover yourself with our tests. Soda, a pixel-art cat, is your coach. Think of it as a smart quiz and a fact of the day in one. And everything works offline, wherever you are. HOW IT WORKS • True or false. Each card is one short claim: decide whether it's true and find out why in a sentence or two. • It adapts to you. KnowSoda measures how well you know each idea and serves the next card right at the edge of your knowledge. • What you learn sticks. With spaced repetition, each idea comes back just as you start to forget it. • Plenty of variety. "Did you know?" fun facts, pick-one-of-two questions, guess which number is higher, and an illustrated story in every subject, with hundreds of pixel-art animations. SODA'S LIBRARY 150 great books, from Plato to Kahneman, with their summary and key ideas. As you learn in an area, new books arrive on your shelf, and their ideas come to your cards as if you were reading them. Mark your favourites and share your library.
