Engage in learning science and math with the award-winning PhET simulations! 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 PhET HTML5 sims (over 75 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 iPad app delivers these exclusive features:
• Offline play: learn on the bus or at the park without a WiFi connection.
• Multiple languages: app translate 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!

Aerospace engineer student ,


This app is definitely one of the coolest and more intuitive I have used. I am a Ph.D. student in Aerospace, and I usually help my siblings work their homework. This app is perfect to effectively and efficiently get an idea across. I am a native French speaker, and this app allows you to learn in different languages; definitely one of my favorite features.
The app is also perfect for brushing up on stuff I have not seen in a while or for learning new material fast and easily. I am a visual learner and the simulation environment allows me to easily digest the material I am learning. I guess a picture is always better than a thousand words. I am able to quickly gain insight into a new field without having to do extensive literature reviews. I can have intelligible conversations with people whose studies are not related to mine. I think this app consciously helps me becoming a well-rounded scientist.

Overall, I would totally recommend the PhET app if you need to clearly explain or learn some basic scientific concepts, regardless of the language you speak.

Fantastic for teachers!

I have loved PhET for years as a teacher—they’re the best tool I’ve found for teaching complex topics in a way that addresses the vast majority of learning needs in a classroom. The app is super easy to use, and runs perfectly for me. The sims are the perfect combination of fun and educational. It’s amazing to see learners with a wide range of strengths and struggles light up when they discover something new in a PhET simulation. As a former physics teacher, PhET sims are some of the most important tools in my teaching arsenal, and it’s useful to be able to use them on my phone, or to have students use them on their phones! I also love that the sims have been translated into many different languages, as it increases their accessibility to students with a variety of different native languages.

PhET is Phenomenal

It can be tricky as an educator to find high quality, hands-on, and interactive science and math resources for students that are also really easy to implement in the classroom. PhET sims have always been a reliable and wonderful educational tool that encourages kids to WANT to think critically and be challenged. They are also really fun and playful! I am so grateful that there is now an app that makes PhET sims even more accessible and available. Highly recommend to any teacher and anyone with kids!
