Tin Toy vs BounceUI

Tin Toy is your creative canvas for real-time graphics. Inspired by ShaderToy, and designed natively for iOS & iPadOS, Tin Toy lets you write and preview Metal shaders with a seamless, modern interface. Whether you're a graphics enthusiast, game developer, or curious creative, Tin Toy gives you powerful tools to bring your shaders to life. Real-Time Metal Shaders Write fragment shaders in a built-in code editor, or your code editor of choice, and see the results instantly. Flexible Buffer Management View each shader buffer individually or all at once. Feed shaders with custom inputs like: * Images * Video * Live camera feed * Mouse & keyboard (if attached to device) Snapshot, Record & Share Capture still frames or record high-quality videos of your shaders in action with a click. Self contained document bundles include the shaders and all its buffer assets for easy sharing and collaboration. Built-In Debugging Tools Capture frames and inspect them using Xcode for pixel-perfect debugging. Perfect for: * Learning Metal shader programming * Rapid prototyping of visual effects * Creating generative art 100% Free No ads. No upsells.

BounceUI is an interactive laboratory for exploring interface behaviour. Some things can't be understood from documentation alone. A document can tell you that dampingFraction controls overshoot, but it can't make you feel the difference between 0.2 and 0.8. It can describe materials in a table, but it can't let you place an image beneath them and see how legibility changes. BounceUI lets you experiment with interface behaviour through live, interactive specimens. Open one, drag a control, and see the result immediately. When you find a combination you like, tap Code and copy the SwiftUI that produces it. WHAT'S INSIDE Six sections, each exploring a different part of interface design. Foundations — Explore semantic colour across appearance and contrast settings, Dynamic Type, layout, symbols, shadows, corner curvature and materials. Components — Experiment with familiar controls and adjust the system parameters that shape how they look and behave, alongside custom variations. Inputs — Explore presses, drags, gestures, touch interactions and scrolling behaviours, including situations where multiple interactions compete for the same touch. Motion — Compare springs, curves, transitions and effects side by side. Adjust the parameters and see exactly how each change affects movement. Liquid Glass — Explore navigation, bars and translucent surfaces using the platform's native APIs. Patterns — Experiment with small interaction details that make an interface feel considered, including undo, refresh, swipe actions and haptics. The catalogue grows over time, with specimens added, refined and replaced as better explorations emerge. HOW IT WORKS Every specimen is live. Where a parameter is worth exploring, you'll find an interactive control beneath the stage. The stage stays in place while you experiment, making it easy to focus on one change at a time. Not sure where to start? Named presets take you straight to useful starting points. From there, adjust the controls yourself and save combinations you want to come back to. When you're happy with the result, the generated code reflects your current settings. What you copy is what you just explored. PRIVACY BounceUI runs entirely on your device. No accounts. No network requests. No analytics. No tracking. No ads. No subscriptions. No in-app purchases. Your presets are stored locally and never leave your device. Haptics can be experienced on a physical device.
