DijkstraGraph vs Beautiful Planimetry

Learn, Play, and Explore graph theory and Dijkstra's shortest path algorithm with DijkstraGraph! Create and edit simple graphs and add edge weights. Rearrange the vertices and interact with the adjacency matrix to explore graph and matrix structure. Play through Dijkstra's shortest path algorithm step by step to identify a shortest path between two vertices. Play through the algorithm on the connected graph you create or explore one already created for you! Create and edit simple graphs - Add and delete vertices and edges - Add and edit weights on each edge - Rearrange vertices to explore graph Interact with the adjacency matrix - Tap on a vertex or edge to highlight corresponding rows and columns in adjacency matrix Play or Explore Dijkstra's shortest path algorithm - Play through Dijkstra's shortest path algorithm on the graph you create! - Or Explore the algorithm on a built in demo graph - Choose a start and end vertex then follow the instructions to step through the algorithm - Complete each step successfully to advance to the next part of the algorithm - After completing the algorithm, use the results to identify the shortest path Run - Don't have time to play through the algorithm?  - Choose a start and end vertex and run the algorithm to identify shortest path

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.
