PhET Simulations

University of Colorado Boulder

About this app

Whether understanding atoms, exploring energy, or mastering multiplication, there is a sim for every learner. Perfect for at home, in class, or on the road, this app delivers all the award-winning PhET HTML5 sims (over 85 sims) in one easy-to-use package.

Developed by experts at the University of Colorado Boulder, PhET sims are used by millions of students every year. The PhET app delivers these exclusive features:
• Offline play: learn on the bus or at the park without a WiFi connection.
• Multiple languages: app translated in many languages (great for bilingual learners).
• Favorites: pick your favorite sims and create your own custom collection.
• Automatic updates: get the latest HTML5 sims as soon as they are released.
• Easy sorting: find the right sims for you.
• Fullscreen: maximize your screen real estate for optimal sim exploration.

PARENTS: Engage your child in science and math discovery.
TEACHERS: Your favorite HTML5 sims at your fingertips, even without internet access.
ADMINISTRATORS: Optimized for school use, so your teachers will be seamlessly up to date.
STUDENTS: Tell your parents there’s an exciting app for learning science and math.

Note: The app does not include PhET’s Java or Flash sims. In addition, although we are currently working on improving the accessibility of our sims, most of the sims included in this app do not include keyboard navigation or screen reader access. As accessible sims become available, they will be updated within the app.

Proceeds from the app support the development of more HTML5 sims. On behalf of the PhET team and the students whose lives you have helped improve — Thank you!

Ratings and reviews

I have been fan PhET for a long time, and it is great to see it in app form. As a physicist I can only talk about the physics apps, but these are very good, easy to use and designed in such a way to illustrate the core underlying physics. I can see the potential of this during a time of remote teaching and learning; learners can now access a wealth of physics and develop their understanding. Well done Phet!

I have taught Physics with PhET for years - their simulations make concepts clear. Now students and anyone interested can explore them in a neat app environment - the menus get you to the topic swiftly and everything works as it should. All the old favourites and so much more than I knew about... There's a whole raft of Chemistry resources I hadn't been aware of. The package will capture students' imagination and they'll investigate more topics than they came for!

These are fantastic! PhET has been used in my classes for Earth Science, Chemistry, and even AP Chemistry for years, but app makes this extremely accessible, especially in the virtual setting where this can be a really powerful tool. The digital tools are simple to use, students find their use to be intuitive, and the cognitive load can be spent on the science rather than figuring out the program. Thank you for all you've done to create such a great learning tool!
