About

MARVLS

Features
Read full description

Augmented Reality Models of topics in the first semester of a physics course including vectors, centroids, forces, impulse, momentum, projectiles, circular motion, torque, right-hand rule, and simple harmonic motion. You'll need a Merge Cube ( link included to download from the internet). Click on different button to navigate to different topics. Click on View in AR to view the model. Hold the Merge cube so that your camera can see it well. Move the cube around until you see the model. Click on the buttons to interact with the model. Click the back button to get back to the info screens or to the main screen.

Stuck on a physics problem? Just take a photo. **PhysicsLab AI** uses AI to analyse physics problems from photos and deliver complete step-by-step solutions โ€” the topic, given values, the key formula, fully worked calculations, and the final answer. **Solve Any Physics Problem** Point your camera at any physics question and PhysicsLab AI identifies the topic, extracts the given values, applies the correct law, and walks you through every step. Covers mechanics, thermodynamics, optics, electricity, and waves. Powered by Google Gemini AI. **20+ Interactive Experiments** Build real intuition with hands-on simulations across four branches of physics: inclined planes, projectile motion, and spring oscillators in Mechanics; ideal gas law and heat transfer in Thermodynamics; lens and mirror equations in Optics; and Ohm's law with live circuit diagrams in Circuits. Drag sliders and watch every value update instantly. **Flash Cards & Solve History** Study with 40 built-in formula flash cards covering all major physics topics. Every problem you solve is saved locally on your device โ€” search by topic and revisit past work anytime. **Perfect For** โ€ข High school and university physics students โ€ข Anyone working through problem sets or exam preparation โ€ข Teachers looking for instant worked examples โ€ข Curious minds who want to understand the physical world **About Physics Problem Solving** PhysicsLab AI covers the full range of standard physics topics: Newton's laws, pressure and buoyancy, thermodynamics, wave optics, Ohm's law, and more. Solutions are generated by Google Gemini (via Replicate) and are intended for educational reference. Always verify important work with your teacher or textbook. **Privacy First** All solve history is stored locally on your device. Photos are only sent for AI analysis and are never stored on any server.

Verdict

The call

MARVLS and PhysicsLab AI are too close to call on the numbers: across 5 compared parameters โ€” price, ads, in-app purchases and device support among them โ€” neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
