Sapling Isle

Explore planets, black holes, forces, light, electromagnetism, atoms, and quantum patterns through hands-on bilingual science experiments.

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.
