Ruckus: Racket for iOS
iPhone coding app 'Ruckus' sparks Scheme vs Racket squabble
TLDR: Ruckus brings the Racket programming language to iPhone/iPad with local execution and slick features. Comments erupted into a Scheme-vs-Racket showdown, jokes about ruqqus, and worries about students using it for homework—making mobile coding feel both powerful and a little mischievous.
Ruckus just dropped, bringing the Racket programming language to iPhone and iPad, and the comments immediately turned into tech theater. The app runs everything locally, shows output as it happens, and packs crowd-pleasers like Rainbow Parentheses, smart indentation, and moody color themes (Dracula! Nord! One Dark!). It even plays nice with Apple Shortcuts and widgets, so you can run code from your home screen, and opens .rkt files from Files. Download it on the App Store.
Then the debate: Scheme loyalists rushed in. One fan touted LispPad Go for its Scheme R7RS standard, while admitting Racket’s huge library collection makes it tempting. Another linked Pixie Scheme for iPad, adding more fuel to “Which Lisp-y cousin should you pick?” Meanwhile, branding got love with “Ruckus is an inspired name,” and one commenter misread the headline as the defunct site “ruqqus,” cue nervous laughter. The most relatable hot take: students will absolutely do assignments on the bus now. Drama aside, folks are excited to code on the go, and the neon bracket colors are basically a vibe. Verdict from the crowd: mobile coding just went from novelty to dangerously convenient, and yes, we’re all about to start a little Ruckus. Right now.
