AlgoSpark vs Beautiful Planimetry

“AlgoSpark” is an app that participated in the 2025 Swift Student Challenge, but unfortunately, it didn’t win. “AlgoSpark”是一款2025 Swift Student Challenge参赛App，但很遗憾的是，此APP并未获奖。 “AlgoSpark” offers various algorithm courses, including “Introduction to Algorithms,” “Programming Structures,” “Sorting Algorithms,” “Searching Algorithms,” and more. These cover both fundamental and classic computer algorithms. “AlgoSpark”为您准备了多种计算机算法课程，包括“认识算法”、“程序结构”、“排序算法”、“搜索算法”等等计算机基础与经典的算法。 Once you complete all the courses, you’ll earn your very own “Algorithm Trophy”! 当你完成所有算法课程之后，你可以获得一个专属于你自己的“算法奖杯”！ Github: https://github.com/abc2754667876/AlgoSpark

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.
