Strengths and trade-offs
PhET Interactive Simulations — where it wins
- 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
Where it doesn't
- 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
Atomency — where it wins
- 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
Where it doesn't
- 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
- PhET Interactive Simulations8.9/10 · Free plan · paid from $0.99
