Abagination: Mental Abacus

Abagination – Abacus & Mental Math for Kids Abagination turns the traditional Japanese abacus (soroban / そろばん) into a colorful, visual tool for mental math and mental arithmetic — built to be read at a glance, not counted bead by bead. On a traditional abacus, every number takes a moment to count out. In Abagination, every digit lives inside its own colored, shaped badge — a circle, a dome, or a square, depending on place value — so you recognize a number instantly, the way you read a traffic light without counting its bulbs. Even the rod each bead slides along is striped to match, so the whole column tells a visual story of the number it holds. It's a faster, more intuitive way to learn place value, counting, and mental math than a traditional wooden abacus. 100% FREE — NO ADS, NO SIGN-IN, NO DATA COLLECTED Just open it and start counting. No account required. HOW IT WORKS Nine full columns, from single units up to hundreds of millions Five bead shapes — star, half-circle, circle, triangle, and square — each with its own fixed color Tap any bead to jump straight to a value, or drag through the stack like a dial Distinct sound cues for extra sensory feedback Clean, distraction-free design for landscape use and quick daily practice WHY IT'S DIFFERENT Most abacus apps recreate a wooden one exactly as-is. Abagination adds a full color-and-shape system on top, so the goal isn't just moving beads — it's training your brain to picture a number instantly. WHO IT'S FOR Great for kids learning to count and understand place value for the first time, and for anyone practicing mental arithmetic and brain training — no age limit, just numbers.
