MoleculAR vs PraxiLabs

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.

PraxiLabs provides virtual science labs and educational content for learners and education providers. Its simulations cover biology, chemistry, and physics, with more than 220 available in the Semester and Annual plans. Learners interact with experiments in 3D, can repeat them, track progress, and receive immediate feedback. Oxi, described as a virtual science lab partner, provides personalized guidance during simulations. The platform also includes multiple-choice quizzes and assessments, reports, and analytics. Individual subscriptions are limited to one user: the Free Plan gives one month of access to three simulations, while the Monthly Plan provides any 10 simulations. Semester and Annual plans include access to all 220-plus simulations. The School plan lists Moodle, Blackboard, and other LMS integrations, plus a built-in mini-LMS; Teacher and University plans are also offered by quote. PraxiLabs runs online in a modern browser on a computer or laptop, with no installation required. The Free Plan costs nothing, the Monthly Plan $6.99 a month, the Semester Plan $29.99 a month, and the Annual Plan $44.99 a year.
