## What is EqualMath?

Designed for Apple Pencil and iPad, version 3.1.6 now lets you quickly sketch with basic elements — points, lines, and shapes — to support theoretical exploration. Function graphs are included.

Core features are free.But includes some paid features: linked point function, hidden circle and color block function, creating more than 5 folders, radian display in the plane coordinate system, 3D coordinate system, vector arrow, parametric equation, water drop coloring, etc.

Beyond geometry, sticky notes are central: pin them to the canvas to highlight key steps, while unwanted ink can be erased to keep your workspace clean.

### Additional Features
1. **Handwritten uppercase letter recognition** – instantly names vertices as you draw geometric figures. Turn it off to use freeform handwriting for names.  
2. **Export to Photos** – one-tap export with no watermark.  
3. **Import from Photos** – insert an image directly onto the canvas (display only, no recognition).  Supports importing PDF files.
4. **Points, lines, and shapes** – select what you need. A key highlight: drag from a vertex of any shape to create a new point – no need to open the menu.  
5. **Lasso tool** – select content or activate locked geometry elements. For points, three selection methods are supported: draw a line near the point, draw a line that passes through the point, or draw a small circle around it.  
6. **Paint bucket** – fills enclosed geometric figures and regions, dynamically sensing surrounding areas to some extent.  
7. **Infinite canvas** – the canvas automatically expands in all directions as you add more ink.  
8. **Function graphs** – plot single-variable expressions and parametric equations.  
9. **Multi-point linkage** – explore geometric problems involving multiple moving points.  
10. **3D coordinate system** – the current release introduces a 3D coordinate space where you can place points and set spatial coordinates. 
11. **3D Geometric Shapes: triangular prism, quadrangular prism, cylinder, cone, triangular pyramid, quadrangular pyramid
