Numerithm brings number theory and beginner programming together in one guided learning app. Learn ideas in small steps, run Dart code, and solve challenges with exact numerical answers. LEARN DART THROUGH NUMBERS Start with approachable lessons on values, variables, conditions, loops, totals, and functions. Then use those skills to explore factors, primes, multiples, common factors, number patterns, remainders, cycles, and other useful ideas. WRITE AND RUN REAL CODE Use the built-in Dart workspace to try an idea, print intermediate values, and calculate an answer. Starter code helps you begin without forcing one solution. Programs run locally with time limits and cannot access your files or the internet. SEE CODE ONE STEP AT A TIME Use the step-by-step view to follow each instruction and watch variable values change. This makes loops, conditions, and calculations easier to understand. SOLVE NUMBER CHALLENGES Each challenge explains the mathematical idea, gives a clear numerical goal, and offers hints when needed. Enter one number to check your answer, or use code to explore a larger search. KEEP YOUR WORK - Save lesson and challenge code automatically - Store useful code snippets for later - Track completed lessons and solved challenges - Earn learning achievements - Create separate local learner profiles with names and avatars LEARN COMFORTABLY - Read-aloud controls with adjustable speech speed - Light, dark, and system appearance choices - Friendly explanations that remain mathematically accurate - Local progress with no account required Introductory lessons are included at no cost. A one-time Full App Unlock opens the complete lesson collection for every learner profile on the device. There is no subscription. Whether you are beginning to code or want a practical way to explore number theory, Numerithm gives you a calm place to learn, experiment, and solve.
