This app simulates primary and secondary school physics experiments, allowing users to understand the basic principles and usage methods of physical experiments through interactive simulation operations. It facilitates the learning, understanding, and review of physical principles, making it suitable for primary and secondary school students and physics enthusiasts to learn and comprehend physics knowledge. It can also be used for classroom teaching demonstrations by teachers and for leisure and entertainment during breaks. The simulated experiments include: 1. Vernier Caliper: Simulates measuring the outer diameter, inner diameter, hole depth, and length of a nut. 2. Balance: Simulates measuring the mass of cherries, rings, and diamonds. 3. Equilibrium of Two Forces: Measures the magnitude and direction of two forces in equilibrium using two spring balances, demonstrating Newton's Third Law. 4. Equilibrium of Three Forces: Measures the magnitude and direction of three forces in equilibrium using three spring balances, demonstrating the parallelogram law of force composition and decomposition. 5. Newton's Second Law: Measures the acceleration of uniformly accelerated linear motion using a 50 Hz punching timer, demonstrating Newton's Second Law. 6. Mechanical Resonance: Demonstrates the resonance principle through the resonance of pendulums with different string lengths. 7. Reflection and Refraction of Light: Demonstrates the laws of reflection and refraction of light by measuring the reflection and refraction angles of lasers with different frequencies in different media. 8. Convex Lens Imaging: Demonstrates the imaging principle of a convex lens by measuring the distances of real and virtual images, the distance of the candle flame, the heights of the real and virtual images, and the height of the candle flame. 9. Ohm's Law: Demonstrates Ohm's Law and Kirchhoff's Voltage and Current Laws by measuring the voltage and current in series circuits, parallel circuits, series-parallel mixed circuits, as well as short circuits and open circuits. The screen supports pinch-to-zoom gestures for easy measurement and observation.

Verdict
The clearest difference is price: PraxiLabs at Free against Phys. Lab's $4.99. PraxiLabs also leads on iOS requirement (12.0 vs 15.6). Phys. Lab's advantage is update cadence (every 10 days vs monthly). On ads, in-app purchases and device support there is nothing between them.
