## What is Sapling Isle?

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.
