LispPad Go vs Shader Playground

LispPad Go is a simple, lightweight, integrated development environment for developing and running Scheme code on iOS. The language supported by LispPad Go is based on the R7RS standard of the Scheme programming language. LispPad Go provides the following components: • A fully integrated Scheme interpreter • A console with a read-eval-print loop to interact with the interpreter • A text editor for writing Scheme code, supporting syntax highlighting, smart indentation, parenthesis matching, etc. • A large range of libraries, including iOS-specific libraries e.g. for networking, graphics, audio, databases, archival, text processing, etc. • Support for the Shortcuts app, allowing the execution of LispPad programs as standalone applications The Scheme dialect supported by LispPad Go provides the following features: • R7RS-compliant libraries • Hygienic macros based on syntax-rules • First-class environments • call/cc, dynamic-wind and exceptions • Dynamically-scoped parameters • Multiple return values • Delayed execution via promises and streams • Support for the full numerical tower consisting of arbitrary size integers, rationals, real numbers, and inexact complex numbers. • Unicode strings and characters • Vectors and bytevectors • Text and binary ports • R7RS-compliant extensible records • R6RS-compliant hashtables and enumerations • Threads

Shader Playground is a powerful real-time shader editor built for iPhone and iPad. Write Metal fragment shaders, see results instantly at 60 FPS, and export your creations as images or videos. REAL-TIME PREVIEW Write code and watch your shader come alive instantly. The live preview renders at 60 FPS with full support for standard uniforms: iTime, iResolution, iMouse, and iFrame. SHADER EDITOR WITH SYNTAX HIGHLIGHTING A dedicated code editor with Metal Shading Language syntax highlighting, monospace font, and smart keyboard tools — designed for comfortable coding on mobile. BUILT-IN SHADER LIBRARY Get started immediately with 10 ready-to-use shaders including plasma, Mandelbrot fractals, raymarched 3D scenes, Voronoi patterns, ocean waves, and more. Learn by exploring and modifying working examples. MULTI-PASS RENDERING Build complex effects with up to four buffer passes. Chain textures between passes to create feedback loops, blur effects, and advanced post-processing pipelines. TOUCH INPUT Map touch and drag gestures directly to shader uniforms. Create interactive visual experiences that respond to your fingertips. SAVE & LOAD PROJECTS Save your shaders locally and pick up where you left off. Build your personal library of custom effects. EXPORT Capture the perfect frame as a PNG image or render smooth MP4 videos at custom resolution, duration, and frame rate. Save directly to your Camera Roll or share anywhere. Whether you're a graphics programmer, creative coder, student learning GPU programming, or a visual artist exploring generative art — Shader Playground gives you a complete Metal shader development environment in your pocket.
