Algernon is a 2D geometry calculator and CAD tool that allows users to construct geometric elements with parametric relationships. Changes to variables or elements automatically update the geometry.
Algernon is primarily aimed at engineers and mathematicians, both practicing and studying. It is also suitable for designing or checking mechanical details and architectural layouts.
Algernon supports the construction of points, lines, and circles. It also includes constructions for intersections, bisections, and tangents, including solving for a circle tangential to three others.
Yes, mathematical formulas can be specified as parameters for elements like position and radius. You can also create variables, use geometrical elements within formulas, and even use time to create animations.
Drawings can be saved, printed, and emailed. They can also be exported in PDF format for sharing or printing, and as DXF files for compatibility with other CAD software.
Algernon uses an associatively parametric approach with a simplified interface. It automatically determines construction types based on user input, keeping the UI clean while maintaining sophistication.
No, Algernon does not contain advertisements. It is a paid application with a one-time purchase price.
Algernon is available for iPhone, iPad, and iPod touch devices, indicated by its age rating of 4+.
