Water Simulator vs Sand & Sky

Turn your screen into a little fluid playground. Tap to create water particles and watch them gather, flow, splash, and bounce through a touch-responsive physics simulation. POUR, WATCH, EXPERIMENT Start with the basic water simulation and 50 particles. Touch the screen to add a stream, watch how particles interact, and clear the scene when you want to begin again. Haptic feedback and an FPS readout add another layer to the experience. CHANGE THE WAY LIQUID MOVES An optional Pro subscription unlocks gyroscope gravity controls, additional fluid presets, and physics customization. Try water, honey, oil, mercury, or lava-inspired settings, then adjust available color, viscosity, surface tension, bounce, and particle-size controls. • Tilt your device to change gravity with Pro • Compare the feel of thick and thin simulated liquids • Try different particle colors and sizes • Change the physics and observe the result • Use the sandbox at your own pace, without scores or deadlines FREE AND PRO Basic water and the 50-particle tier are free to try. Pro removes the free-tier particle cap and unlocks the listed customization features; practical performance still depends on your device and simulation settings. Plans and local pricing appear before purchase. Subscriptions renew automatically unless canceled through your Apple account settings. A sensory toy for curious hands and a quiet pause. The named presets are simulated particle behaviors, not actual liquids or a laboratory measurement tool. No claim is made to diagnose or treat ADHD, anxiety, or any other condition.

Sand & Sky is an endlessly satisfying particle physics sandbox — drop materials, watch them interact, and discover what happens when science meets creativity. Pour water and watch it fill every corner. Drop lava onto ice and forge obsidian. Ignite gunpowder and set off chain explosions. Build walls, draw mazes, and experiment unique materials that each behave according to their own rules. REACTIONS & COMBINATIONS Every material interacts with others in surprising ways. Water meets lava and creates stone. Lightning strikes sand and fuses it into glass. Acid dissolves almost everything. Discover all the reactions in the built-in Reactions guide. FEATURES · Realistic fluid simulation — liquids fill containers and accumulate naturally · Flip gravity in any direction — up, down, left, or right · Wind tool to push particles across the screen · Adjustable brush size and simulation speed · Undo button and sandbox clear · Unique sounds for every material Whether you're building elaborate contraptions, running experiments, or simply watching particles fall — Sand & Sky is the perfect zen sandbox to lose yourself in.
