ChemLab vs MoleculAR

ChemLab is an interactive chemistry lab simulation for high-school and college general chemistry. It pairs simulated experiments with a lab notebook for theory, procedures, and student observations. Pre-designed labs cover subjects including acid-base reactions, electrochemistry, equilibrium, gas laws, kinetics, redox, and stoichiometry, with additional simulations available from third parties. Animated experiments, plug-in lab extensions, and tools to record and replay demonstrations support instruction. Standard lets students run simulations; Professional adds Lab Wizard tools for instructors to run, edit, and create labs, plus an expandable chemical database. Professional users can capture a simulation, add comments, and save a distributable demonstration for Standard users to play back. The product lists RasMol integration and an integrated periodic table application with a quiz. It is described for distance learning, pre-lab work, demonstrations, and lab run-throughs, including experiments that are dangerous, environmentally hazardous, expensive, or lengthy. It is available in English, Spanish, French, and Italian. Single-user Standard licenses start at $33.99, paid once.

MoleculAR is a free augmented-reality app for chemistry learning on Android and iOS. Users scan QR codes to open three-dimensional models of molecules, molecular geometries, and orbitals, then rotate and zoom them for different views. The app focuses on VSEPR molecular geometry and visualizing complicated molecules. A downloadable QR library provides available structures at no cost. Its reference includes molecules, s, p, d, and f orbitals, plus animations for Newman projection, the SN2 reaction, and ring flip. The maker describes MoleculAR for students and educators in chemistry education and accepts feedback or requests for new molecules by email. The privacy policy says the app does not collect data, while third-party services may collect identifying information. Error logs may include an IP address, device name, operating-system version, and usage date and time. The service does not address individuals under age 13.
