Suitable for pencil and iPad use, the current 1.1 version can quickly draw based on basic elements such as points, lines, and surfaces to assist in theoretical exploration
Basic functions are free, and professional functions require a one-time purchase
In addition to the geometric part, the note taking function is also one of the core functions. It can be fixed on the page to display the most important steps, and unnecessary and useless handwriting can be erased to avoid wasting energy
In addition, there are the following functions:
1. Handwritten capital letter recognition: mainly used to quickly name vertices when drawing geometric shapes. If this switch is turned off, handwritten naming is supported
2. Export images to album: One click export without watermark
3. Selecting images from the album: One click import, only displaying images, not recognizable
4. Point line surface: Choose according to your needs. The key is that a new point can be pulled from the vertex of a certain shape on the page, which can replace selecting to generate a point element from the menu.
5. Lasso tool: The key is the selection of point elements, which can be done in three ways: draw a line near the point with a lasso, draw a line through the point element with a lasso, or draw a small circle around the point element with a lasso.
6. Colored droplets: can color enclosed geometric shapes and areas, and to some extent, can dynamically perceive changes in the surrounding area
7. Canvas extension: As the handwriting increases, the canvas size will also dynamically expand outwards, but canvas scaling is not currently supported
