Topics such as gauss law were hard for me to visualize and this app resolved that problem. I also like that the app offers a description of each model before clicking on it. ### 5/5 — Physics Concepts *2023-04-18, version 2* This app helped me understand and visualize the 2D and 3D representations of magnetic and electric fields. There is not only a 3D image but most of the images also show how particles are effected by the magnetic/electric fields. The 3D representation also shows the variable within physics equations. Overall this app has been very useful in expanding my physics knowledge and it is just fun to use. ### 5/5 — Amazing app, changed my life!! *2023-04-18, version 2* This app has changed how I have learned physics. With the cool 3d visualizations, I can engage with the models and understand fully with the mathematical equations about the concepts I am learning. Abstraction can virtually go out the window!! Because now I can see it with the cube and see it right there in the palm of my hand!!!!! Amazing, a must for teaching! ### 5/5 — Cool App *2023-04-18, version 2* This app is extremely helpful because it helps you visualize each variable from multiple physics equations in a 2D and 3D space. It is often the bridge between what you learn in class and real life. ### 5/5 — MARVLS app review *2023-04-17, version 2* This app have been extremely helpful to visualize the topics we have been learning about during lecture. It is quite hard to picture a 3D object on a 2D white board but because the app has a 360 view it allows you to fully see what it going on. My favorite part of the app is when you can turn on and off currents to see how that changes the picture we are looking at. ### 5/5 — Amazing app *2023-04-15, version 2* This is app is one of the incredible apps I have ever used. It is very helpful for student engagement and understanding concepts outside of the class. If you are a physics student you need this app. ### 5/5 — A MUST HAVE *2023-04-14, version 2* This app helped me to further my knowledge in various physics concepts covered in class. Being able to see concepts in both 3D and 2D made it much easier to understand and visualize it. The app gives mathematical equations to parts of the 3D models for those more math inclined. Any physics student needs this app, highly recommend!! Get yours today!! ### 5/5 — Great App! *2023-04-13, version 2* This app has helped me gain a better understanding of physics concepts through 2D and 3D models! :) ### 5/5 — BEST APP EVER *2023-04-12, version 2* This app is the most insanely awesome tool I’ve ever used!!! It absolutely helped me gain a better understanding of various physics topics by being able to view them in 3-D and manipulate/move the cube around. If you’re a physics student, you NEED this app!! ### 5/5 — Helps give a 3D point of view *2023-04-11, version 2* This app makes understanding specific physics topics in both 3D and 2D forms easy. The app also gives equations for specific concepts and shows what part of the model relates to the equation. ### 5/5 — Awesome app *2023-03-28, version 2* It really helps me understand topics in physics through a 3D interactive lens. ## Most critical reviews (10 lowest-rated) ### 4/5 — Great learning tool! *2024-04-11, version 2* An amazing tool to aid in learning e&m, with great visuals. It helped a lot to visualize and understand how different components work. These visuals along with a lecture is an absolute godsend ### 4/5 — MARVLS *2024-04-09, version 2* The app is great! It really helped me cement some concepts in my mind by interacting and moving around 3D models. Being able to see a lot of the concepts that were being explained just mathematically actually happen in real time was very helpful. ### 4/5 — App is Amazing! *2024-04-09, version 2* The app does very well at visualizing multiple concepts, such as magnetic fields and electrical fields. I love that you have have 2D models to 3D, and all models follow the right hand rule method. It makes learning these concepts so much easier. When rotating the cube itself, none of the visuals are laggy or take a while to connect, it actually is represented very well visually and easy to use. You can also rotate the cube to see the 3D models from different angles, such as if you need vectors to point away it towards you, and how that affects other parts of the model. Being able to see which parts of the 3D model are represented in certain parts of equations is also useful, such as being able to see the B field vector and where it is located/ where it is used in the mathematical equations. ### 4/5 — Extra Credit Review E&M *2024-04-09, version 2* This app is very useful, as it provides a nice visual representation of physics related problems. It is also a great hands on app for all students using it and can provide useful information to those who are physics are applied physics majors. However, the one thing I believe that could be improved is having one physics app with different subsections for each specific physic class like phys I and phys II and content within each class. Other than that, I believe the 3D and 2D visuals are very well and provide a great visual representation of each problem. Overall great app. ### 4/5 — App is helpful, but not perfect. *2023-04-25, version 2* This app works fairly well but it has its issues. The visualizations are well made and help with the topics but some of the buttons don’t seem to work properly. For example, some of them are toggles that require you to tap them twice before the change registers. This however is minor, otherwise the app works great with its 3D wire, magnetism, and many other visual aids. The interactivity, especially with the equation variables really helps put physical and paper together. ### 4/5 — Great Tool for learning Physics *2023-04-14, version 2* I like how the 2D/3D representations are displayed on the cube, and how they portray the idea of how the concept of physics works, where the cube can be rotated, moved around, and be seen further away from the camera. The app provide the important equations and variables involved in topics such as Gauss’s and Amperes Law. This app is a very good learning tool for visual learners like myself to gain a better understanding of the topics that I would have trouble understanding in class. I definitely recommend this app! ### 4/5 — Useful information *2023-04-13, version 2* This app is great help to learning physics along with the visual arts that help see 3-D images. I find that this app has helped me with understanding the concepts of physics and has helped me a lot. ### 4/5 — Useful App *2023-04-11, version 2* Using this app in physics class helped me to understand the concepts we were learning much better. I was able to physically hold the cube to move the 3D version of the diagrams around however I wanted, which helped me visualize them more compared to a 2D model on paper. ### 5/5 — Awesome!!!!!!!!! *2024-04-11, version 2* This app is super helpful visualizing abstract concepts and 3D models!! It is also really helpful in applying the RHR and seeing how physics concepts visually work ### 5/5 — Very good App *2024-04-11, version 2* This app helps me to visual the concepts learned in physics 2. Often, it can be fiscally to visualize things like magnetism and electric field. With the MARVLS app it makes it very easy to see these concepts in 3D space. ## Most praised reviews (8 highest-rated) ### 5/5 — Physics II *2024-04-09, version 2* This app is very helpful. The 3D models improved my understanding of the topics, especially with magnetism. ### 5/5 — Awesome Visualization Tool For Teachers And Students *2024-04-09, version 2* The MARVLS: Physics ll E&M is a wonderful app that I was able to test out that uses VR to help visualize 3D concepts in our 2D world. The use of the MERGE cube is very ergonomic and always seamless 360 degree range of motion in all directions. Students will no longer have to use imagery to tackle higher level problem solving with the abilities of the MARVLS app! ### 5/5 — Very useful! *2024-04-09, version 2* This app makes visualizing physics concepts much easier. It uses 3D physics models to help better understand abstract concepts. Great tool! ### 5/5 — Great app *2024-04-09, version 2* This app makes it easy to visualize challenging physics topics and concepts. The 2d and 3d models allow you to see the movement or fields of different objects or scenarios. You are able to rotate the cube to see different angles of a certain concept. The hands on app makes it easy to conceptualize topics like Lorentz force. My favorite feature is that when using the right hand rule in the app the different components are highlighted so that you understand what each component means and what it actually does. ### 5/5 — Very Helpful *2024-04-08, version 2* The MARVLS app is really helpful in physics to visualize new 3D and abstract concepts. It connects variables in mathematical equations to parts of 3D models and it allows you to rotate the cube to see all angles of the model. It is helpful too because its color coded and labelled making it easier to understand what you are looking at. ### 5/5 — Siena Physics App *2024-04-08, version 2* Great app overall with many different learning features for E & M, Momentum, Forces, and Vectors. Would recommend to anyone taking classes at Siena college and the cube helps in many different ways! ### 5/5 — MARVLS!!! *2023-04-27, version 2* This app is wonderful. If you're like me, you're definitely someone who needs to be able to see things with their hands and depth. The app allows 2D concepts to easily be translated to 3D models that represent what we're learning in class. In doing so, these models are able to be combined with equations to represent different things that would be more challenging to imagine rather than visualize what the 3D models allow you to see. Being able to hold an object in your hand and have complete control is more gear-turning than your teacher trying to explain what they already know. I think the app features are great and I'd love to see what's to come in the future. ### 5/5 — Great Physics App *2023-04-21, version 2* Really great app for learning physics material and understanding concepts in 2D and 3D! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
