Advertiser disclosure: iTechGuides is reader-supported. Vendors can pay for top positions in our rankings and for a place on other products' pages, and we may earn a commission when you click some links. Bought places stand at the number bought; this page and our disclosure say so. Paying vendors may get a fuller, more detailed review from our editors, and that review can change their score.

Our review
Pros
  • Free web simulations with offline desktop and mobile access
  • Covers chemistry plus physics, biology, earth science, math, and statistics
  • Teacher activities, facilitation guidance, translations, and LMS embedding
  • Covers molecular modeling, reactions, equilibrium, gases, and stoichiometry
  • Guided virtual labs and Chemical Bench activities support varied lessons
  • Teacher assignment builder exports student work for classroom use
Cons
  • Broader than chemistry, so it is not a chemistry-only environment
  • Mobile apps cost $0.99 one time on iOS and Android
  • Built-in assessment workflows are not a stated product capability
  • School and district adoption requires a paid license or written authorization
  • Public individual exploration does not provide managed school deployment
  • Its chemistry-and-physics breadth may exceed the needs of narrow use cases
