PE.Mech vs 3DPhyS
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
PE.Mech
Read full descriptionHide full description
This app is aimed at mechanics part and includes 11 experiments about: kinematics, Newton's laws of motion, work and energy, momentum and impulse, periodic motion etc. It has some features: 1. You can set ideal conditions, for example: friction=0, air resistance=0, any gravity acceleration; 2. Show changing physical values by function diagram, free body diagram, energy diagram etc in real time to compensate for the lack of real experiments; 3. You can set any reasonable parameters to see different results, and calculate them by the descriptions to test your understanding; 4. Suitable for use in high school and college students; I hope this app can help you in your physics learning.
3DPhyS
Explore fundamental physics concepts through interactive simulations. Adjust parameters like initial velocity and bounce coefficient to understand phenomena like free fall, projectile motion, and circular motion. This app supports learning in multiple languages.
- Interactive physics simulations
- Adjustable experiment parameters
- Multiple physics experiment modules
- Multilingual interface
- Free to download and use

3DPhyS offers a fun way to learn physics using Physics Simulator! Localized the home scene into Japanese, English, Chinese, Spanish, German, French, Portuguese, Russian, Indonesian, Arabic, and Korean! Some parts are still in Japanese, but you can still simulate the game even if you do not understand Japanese! The following courses of experiments are available Free Fall Vertical projection Horizontal projection Oblique projection Monkey Hunting Bounce coefficient Object sliding on a slope Buoyancy force Frictional force Momentum conservation law for two-object collision (bounce coefficient) Momentum conservation law for splitting Circular motion Circular motion under gravity Single swing of pendulum Universal gravitation In each experiment, you can freely change parameters such as initial velocity and bounce coefficient! Please use this app to improve your performance! If you have any comments or typos, please feel free to contact us.

Verdict
The clearest difference is price: 3DPhyS at Free against PE.Mech's $0.99. 3DPhyS also leads on update cadence (fortnightly vs every 2 months) and device support (3 vs 1). PE.Mech's advantage is ads (none vs shown). On in-app purchases there is nothing between them.
