Collisions Higher Education vs MolView

Collisions Higher Education is a digital game system for teaching and reviewing chemistry in college courses. It aligns with over 55 core concepts in introductory and general chemistry, organized into eight content areas: Radii Trends, Ionization Energy, Acid Strength, Lewis Structures, Ionic Bonding, Energy in Phase Change, LeChâtelier, and IMFs. Each game includes leveled challenges and an exploratory sandbox. Instructors can view student progress and performance in a teacher dashboard, and can use content overviews, quick start guides, formative assessments, and extension assignments. Instructor access is listed at free for US-based college and university educators. Student subscriptions cost $15 a year for a 12-month term; accounts are linked to an instructor’s class, and students register through an invitation URL supplied by the instructor. The product is listed for Android, iOS, macOS, web, and Windows. Playmada has ceased operations, while its FAQ says Collisions HE remains available and free to educators and students as of July 1, 2022. The FAQ also says the company no longer provides email, phone, or training support and directs users to a support forum.

MolView is a web application for sketching and viewing small molecules, with API access and molecular modeling support. Its canvas handles structural formulas, reaction arrows, electron-pushing arrows, configurable styles, and keyboard shortcuts. A 3D viewer updates automatically as you edit a molecule. Chemical searches accept common names, IUPAC names, SMILES, InChI, InChIKey, and molecular formulas. Depending on the plan, you can save and load sketcher or viewer content, create shareable links, export structural data or SVG files, use transparent backgrounds, and set image resolution. Developers can embed the sketcher web component in vanilla JavaScript or React and customize its toolbar and diagram style. The free plan needs no sign-up and supports searching, sketching, and viewing, but cannot save diagrams. Paid plans include Student at $9.00 per year, Publisher at $250.00 per year, Academic at $4919.00 per year, and Standard at $9919.00 per year.
