Our review
Pros
  • Dynamic sketches show geometric constraints as objects are manipulated
  • Transformations, reusable macros, and programmed sketches support exploration
  • Free, open-source desktop app runs offline on Windows, macOS, and Linux
  • Drag base elements to update dependent parts of a construction.
  • Supports Euclidean, hyperbolic, and elliptic geometries.
  • Includes automatic proving, loci, CindyLab simulations, and CindyScript.
Cons
  • No proof-practice activities are included
  • No classroom-management tools are provided
  • Desktop deployment does not include a web or mobile edition
  • Its scope centers on construction and exploration rather than proof practice.
  • Classroom and practice features are less extensive than some alternatives.
  • Documentation references older updates, which may complicate onboarding.
