Proof Fidget vs AhaMath

ProofFidget is a puzzle-driven way to learn the feel of doing math: not by memorizing procedures, but by making correct moves, one step at a time, until a proof truly holds together. Each puzzle gives you a clear goal and a partially-complete derivation. You spin the wheel to choose your next move, then commit to a step and watch the proof line up. If you’re right, you progress; if you’re wrong, you learn quickly why it didn’t fit. The result is a tight feedback loop that makes abstract ideas concrete and surprisingly fun. You’ll work across a growing set of subjects, including: Logic and proof techniques: build confidence with implication, contradiction, and structured reasoning. Algebra: make valid transformations while keeping equations balanced, supported by visual “balance scale” diagrams. Number theory: practice modular arithmetic, divisibility, and gcd-style reasoning with intuitive visuals. Geometry and beyond: use diagrams to ground symbolic steps in something you can see. ProofFidget is designed for short, satisfying sessions, but it also rewards deeper play: you start noticing patterns, choosing steps for the right reasons, and developing proof instincts that transfer to real coursework and problem-solving. If you’ve ever thought “I understand the formula, but I don’t understand why,” ProofFidget is built for that moment.

Stop memorising formulas. Start seeing why they work. Most maths apps give you a problem and check your answer. This app shows you the maths — with rich, interactive animations that break every concept down visually, step by step. Watch a circle split into sectors and rearrange into a rectangle to reveal why area = πr². See a tangent line slide along a curve to show what a derivative really means. Follow vectors as they add tip-to-tail on a coordinate plane. Every animation is designed to build genuine understanding, not just drill answers. TOPICS COVERED • Arithmetic — addition, subtraction, multiplication, division • Fractions — equivalences, simplifying, finding missing values • Algebra — one-step and two-step equations, simultaneous equations, factorising, completing the square, quadratic formula, geometric sequences • Geometry — perimeter, area, Pythagoras, circles, surface area, volume, similarity • Trigonometry — SOHCAHTOA, sine rule, cosine rule • Functions — evaluation, composition, slope, inverses, exponential growth • Calculus — derivatives, integrals, related rates, optimisation, Simpson's rule • Statistics — mean, median, range, IQR, normal distribution • Probability — basic probability, complements, independence, expected value, permutations, combinations • Vectors — magnitude, scalar multiplication, addition, dot product, unit vectors • Complex Numbers — powers of i, conjugates, modulus, polar form, Argand diagrams • Physics Foundations — speed, momentum, acceleration, force, work, projectile motion WHAT MAKES IT DIFFERENT ◆ 30+ interactive animations that visually prove why each concept works ◆ Unlimited practice with dynamically generated questions — you will never see the same problem twice ◆ Step-by-step worked solutions and contextual hints for every question ◆ Three difficulty levels per topic so you can build confidence before pushing further ◆ Clean, focused design — no ads, no distractions WHO IS IT FOR Whether you are a student working through school maths, preparing for exams, or an adult refreshing your skills — the visual approach helps concepts stick in a way that textbooks cannot match. Built by someone who believes maths should make sense, not just be memorised.
