Beautiful Planimetry vs MathStepMath

Geometry doesn’t have to feel impossible. When my daughter first opened her geometry book, she looked at the page — circles, triangles, and lines everywhere — and sighed: “Dad, this makes no sense.” I knew that feeling. So I built a way to make geometry visible. With sliders, motion, and colour, she could see how shapes connect — how an angle changes a triangle, how circles hide perfect relationships, how formulas aren’t just rules but reflections of movement. That small idea became Beautiful Planimetry — an interactive geometry world where math comes alive. Instead of memorising formulas, explore how they work. Move a slider and watch a shape stretch, rotate, or reveal a hidden pattern. Suddenly, geometry isn’t about remembering — it’s about discovering. What you’ll find inside Included for free: - Circle Geometry: basics, inscribed angle, right triangle on diameter, law of sines - Circle Area: circle, sector, segment, ring - Thales’ Theorem: parallel lines crossed by an angle - Angle Bisector: see how angles are perfectly divided - Triangle Basics: triangle types, Pythagoras, law of cosines, inscribed circle in a right triangle, right triangle inscribed in a circle Unlock more with one in-app purchase: - Triangle Area: base × height, two sides + angle, Heron’s formula, equilateral triangle - Quadrilaterals: square, rectangle, parallelogram, rhombus, trapezoid, kite - Regular Polygons: triangle, square, pentagon, hexagon, octagon Why students love it - Visual learning — see shapes change in real time - Instant clarity — connect formulas to the figures they describe - Confidence boost — explore before practicing, so exercises feel easier Who it’s for - Students who want geometry to finally click - Teens tired of memorising without understanding - Parents and tutors who want to make math less stressful Beautiful Planimetry was born from a real story: a dad helping his daughter who struggled with math. What started as a simple app to make functions easier has grown into a family of apps that now includes geometry. Stop memorising. Start understanding. With Beautiful Planimetry, geometry becomes simple, visual, and — yes — beautiful.

**Master math, one step at a time.** MathStep is a comprehensive K-12 math learning application designed for preschool, elementary, and middle school students. The name "MathStep" reflects our philosophy: math mastery comes step by step. With 175+ knowledge points covering a complete K-9 curriculum, MathStep helps students build solid math foundations through structured practice. **Complete K-9 Curriculum** From number recognition in preschool to quadratic functions and geometry in middle school, 175+ topics are organized in a clear three-level structure: Stage → Grade → Topic. Each topic is rated by difficulty level for clear learning progression. **11 Practice Modes** Arithmetic (integers, decimals, fractions), Geometry Shapes, Algebra Equations, Clock Reading, Money Math, Statistics & Probability, Number Sense, Measurement, Geometry Theorems, Function Analysis — comprehensive coverage of all essential math skills. **Blackboard-Style Visuals** All illustrations use realistic blackboard-style rendering — geometric shapes, number lines, coordinate planes, angle diagrams, and bar charts are precisely drawn. Professional mathematical illustrations help students visualize abstract concepts. **Voice Feedback** Every question includes audio prompts and feedback. Correct answers receive encouraging responses; wrong answers get gentle guidance to try again. Consecutive correct answers trigger escalating praise to keep students motivated. **Bilingual Chinese & English** Complete bilingual support across menus, questions, options, and voice prompts. Numbers in English mode convert to written words (e.g., "forty-five") for authentic language immersion. Ideal for international school students and overseas families. **Progress Tracking** Automatically records practice count and accuracy for each topic, helping parents and students track learning progress and identify areas needing more attention. **Grade-Level Adaptation** Content difficulty automatically adjusts by grade — preschoolers focus on basic number recognition and shapes, elementary students build arithmetic and applied skills, and middle schoolers advance to algebra and geometric reasoning. MathStep — step-by-step math mastery for every child.
