**The Molecular Model App We Always Wanted** Born from the developer’s own learning experience, K-Mol is a molecular modeling app designed for high school and university students. ## Features ### 2D Mode ・Draw structural formulas with intuitive controls ・Supports up bonds and down bonds, making it possible to represent stereochemical structures ・Includes templates for five-membered and six-membered sugar rings, saving you from the tedious process of drawing them from scratch ### 3D Mode ・A 3D mode that feels like using a real molecular model kit ・A practical alternative to physical molecular model kits, which can be surprisingly expensive ・Recreates bond lengths and bond angles, making it useful for learning from the high school level through university-level chemistry ・viewing molecular models in AR ## Shared Features ・Screenshot: Capture the structural formulas and 3D models you create. Perfect for reports and study materials. ・Save: Save your structural formulas and 3D models inside the app and reopen them anytime. ・Templates: Frequently used structural formulas are available as templates, so you do not have to draw everything manually. ## Important Notes K-Mol is an educational app designed to help students learn about molecular structures, bonds, stereochemistry, and basic chemical visualization. It is not a substitute for textbooks, classroom instruction, laboratory safety guidance, or professional chemical analysis. The molecular structures, bond lengths, bond angles, aromatic representations, templates, and 2D/3D views shown in the app are simplified models for educational purposes. They do not fully represent actual chemical behavior, quantum effects, force-field optimization, experimentally measured structures, or other advanced chemical properties. Do not use this app for laboratory safety, medical, pharmaceutical, environmental, industrial, regulatory, research-level modeling, synthesis planning, handling of hazardous substances, or any other professional or safety-critical purpose. This app does not provide professional advice. The information displayed is intended for general educational purposes only.
