Sapling Isle
Read full descriptionHide full description
Sapling Isle is a multilingual interactive science lab that connects observable phenomena with advanced scientific concepts on iPhone and iPad. Change variables directly, observe how a system responds, read graphs and measurements, then explore the equations, assumptions, and limits behind the model. Explore nature and the universe • Control a 3D Solar System and observe planetary motion and astronomical time • Follow curved light, an accretion disk, and Einstein rings around a black hole Enter a hands-on physics lab • Explore forces, motion, heat, energy, magnetic fields, light, and atoms • Compare heating, compression, and diffusion in a 3D microscopic world • Investigate orbits, waves, entropy, Boltzmann distributions, quantum tunneling, and double-slit patterns Explore at your own depth • Start with direct manipulation and visual feedback • Continue with multivariable comparisons, measurements, and graphs • Go deeper into equations, approximations, and model boundaries • Choose from 10 interface languages • Adaptive layouts for both iPhone and iPad • No account, advertising, or cross-app tracking • Progress, camera frames, and experiment data are handled primarily on device Pick an island, begin with a phenomenon, and follow the evidence toward deeper models.

Verdict
The clearest difference is device support: Sapling Isle at 2 against PhysicsViz's —. PhysicsViz's advantage is iOS requirement (15.0 vs 18.0). On price and in-app purchases there is nothing between them.
