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
CraftOS
This app emulates a classic text-based computer environment, allowing you to write and run Lua programs. It's perfect for learning to code or exploring existing programs from a popular Minecraft mod, all within a retro terminal interface.
- Lua 5.2+ scripting environment
- 16-color text-based terminal
- Virtual filesystem
- Built-in shell
- Extensive APIs
- Compatibility with ComputerCraft programs
- Exclusive graphics mode

CraftOS-PC is a fantasy terminal that allows you to write and run programs inside an ‘80s-style text console. CraftOS-PC emulates the popular Minecraft mod "ComputerCraft", which adds programmable computers to Minecraft using the Lua programming language. CraftOS-PC takes this experience outside Minecraft to allow you to run the same programs anywhere you go. CraftOS-PC provides a set of functions (called APIs) that make it super easy to do simple tasks such as write text to the screen, read files, and more. The simplicity of these functions makes CraftOS-PC great for new programmers, but their power makes it possible to write all sorts of complex programs with less code. If you aren’t ready to write programs yet, there’s already a large number of programs for ComputerCraft that will work in CraftOS-PC, ranging from simple games to whole graphical operating systems. These can be downloaded through the built-in Pastebin and GitHub Gist clients. • Full Lua 5.2+ scripting environment and command-line REPL • 16-color text-based terminal display • Expansive virtual filesystem for program and data storage • Built-in shell with syntax similar to most desktop shells • APIs to easily access terminal, filesystem, Internet, event queue, and more • Built-in programs make it easy to navigate & edit files without a single line of code • Plenty of help documents to assist programmers • Compatibility with thousands of existing ComputerCraft programs • Over 3x faster than Minecraft mod and comparable emulators • Emulation of all peripherals available in ComputerCraft • Easily access configuration from inside CraftOS • Exclusive graphics mode providing up to 256-color, pixel-based screen manipulation • Edit Lua scripts from CraftOS or other code editing apps • Open-source app makes it easy to suggest and contribute changes Documentation on all of the APIs that ComputerCraft provides are available at https://tweaked.cc, and CraftOS-PC’s unique APIs are described at https://www.craftos-pc.cc/docs/.

Verdict
The clearest difference is in-app purchases: LispPad Go at none against CraftOS's 1. LispPad Go also leads on update cadence (every 2 months vs every 4 months) and review sentiment (96% vs 88%). CraftOS's advantage is chart position (#192 vs unranked) and iOS requirement (13.0 vs 17.6). On price, rating, ratings volume and ads there is nothing between them.
