iCrosss Lite is a free educational application designed to make learning solid geometry easy and enjoyable. This unique app allows users to create cross-sections of various polyhedra by defining a plane with three points on the polyhedron faces. Supported polyhedra include regular polyhedra, Pyramids, Prisms, Anti-prisms, Archimedean solids, and their duals, all displayed in a 3D representation for easy rotation. The app features a charming chalkboard drawing style and fonts for a visually appealing experience.

With two viewing modes - 3D and 3D cut - users can explore cross-sections in depth. The 3D cut mode enables users to work with individual solid pieces of the polyhedron after creating a cross-section. Additionally, users can print or email the polyhedron or its section, access detailed information about selected solids, and explore useful formulas and web links. The app also offers a tutorial mode for quick familiarization and the opportunity to unlock more polyhedra by sharing on Facebook. For displaying formulas, a custom rendering engine visualizes LaTeX formula formats.
