PhET Interactive Simulations review
A broad simulation library with offline apps and classroom resources at low cost.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PhET Interactive Simulations is a University of Colorado Boulder project for learners and educators in K–12 and higher education. It provides interactive simulations across physics, chemistry, biology, earth science, mathematics, and statistics. Browser-based HTML5 simulations support online learning, while compatible desktop and mobile apps support offline access. The product suits classrooms, independent study, demonstrations, and lessons that benefit from virtual experiments rather than static explanations.
Its main strength is breadth across subjects and learning environments. Learners can access simulations through web browsers, Windows, macOS, iOS, Android, and select Chromebooks. Educators can use teacher-submitted activities, lesson resources, simulation-specific teaching tips, video primers, classroom facilitation guidance, and active-learning guidance. Simulations can also be embedded in learning management systems and presentations, with integrations including Google Classroom and PowerPoint. Multiple language translations extend its usefulness across different teaching contexts.
The pricing model is straightforward but includes an important distinction. Core web simulations are free for non-commercial educational use, and the project is open source. Official Android and iOS apps are listed at $0.99 one time, while offline desktop applications are available for Windows and macOS. PhET does not present a conventional subscription structure. The product is a strong choice for learners and educators seeking wide subject coverage, flexible delivery, and supporting classroom materials. It is less suitable for organizations seeking a dedicated assessment system or built-in AI features, or for commercial use of the core simulations.
