My Lisp vs Code App
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
My Lisp
A comprehensive Lisp programming environment for iOS and macOS devices. It offers a local interpreter, editor, and extensive libraries for learning and developing Lisp programs, including advanced mathematical functions and symbolic derivation.
- Local Lisp interpreter
- Integrated editor
- Core and mathematical operators
- Advanced mathematics functions
- Symbolic derivation module
- Library and example files
- User and reference manuals

My Lisp is a complete and universal Lisp environment running directly on the iPhone, iPad, and Mac. This interpreter is true to the original John McCarthy Lisp implementation with the fundamental 7 operators quote, atom, eq, car, cdr, cons, cond, along with lambda and label. My Lisp also contains core and mathematical operators borrowed from other Lisp dialects (Le Lisp, Lisp 1.5, MacLisp, Common Lisp and Scheme to name a few) to make it easy to learn, program, and most importantly, enjoy Lisp. It also features built-in functions for advanced mathematics, including complex numbers and numerical analysis (roots and zeros finder, integral approximation). The complete description of the fundamental, core, and built-in functions is available using a set of library functions completely written in My Lisp. My Lisp offers an interpreter and an editor, all working on the iPhone, iPad, and Mac, and most importantly, without requiring any server connection, that is, the interpreter is executing locally on the iPhone, iPad or Mac My Lisp is installed on. Library and example files contain the source code of classical functions and problems solved by My Lisp and may be used as reference to learn Lisp and develop other programs. They include classical puzzles (hanoi and n-queens), basic mathematical functions (gcd, lcm, factorial, fibonacci, prime?), and the historical apply, mapcar and maplist functions. The Lambda Calculus example file contains various functions related to Lambda Calculus and Combinators, with alpha-conversion, beta-reduction, de Bruijn notations, etc. As a special note, the example file Symbolic Derivation contains a complete yet extensible symbolic derivation module allowing to compute the formal derivation of virtually any symbolic function expressed as a Lisp expression. A user manual and a reference manual are available from within the application but also on My Lisp web site (https://lisp.lsrodier.net) and in Apple Books. The complete source code of the library and example files is part of My Lisp. Last but not least, this overview couldn’t end without a sample definition of the notorious REPL function: (define (REPL eval_me) (REPL (println (eval (read)))))

Code App is a MIT-licensed desktop-class code editor for iPadOS with built-in Node.js, Python, C, C++, PHP and Java runtime. We built it because there is nothing else on the App Store provides all these features in one app: * A robust, high-performance text editor (Monaco Editor from Visual Studio Code) * Autocomplete, static code analysis and other language features for Python & Java * First class local file system support * Extensive local language support * SSH / FTP remote connection support (Files and terminal) * Embedded emulated terminal * Git Version Control * Package manager support (pip and npm) * Markdown, themes, server-side snippet execution and more Read Code App's documentation: code.thebaselab.com See the project's source code, roadmap, discussion on GitHub: github.com/thebaselab/codeapp Send us an email: support@thebaselab.com Privacy Policy: thebaselab.com/privacypolicies Terms of Use (EULA): www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is ratings volume: Code App at 301 against My Lisp's 17. Code App also leads on chart position (#3 vs #85) and iOS requirement (16.0 vs 18.0). My Lisp's advantage is price ($3.99 vs $6.99). On rating, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
My Lisp costs $3.99 and Code App $6.99 up front. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.1 for My Lisp against 4.0 for Code App. That said, the two scores are not equally well evidenced: Code App has 301 ratings behind it against 17, so its average is the more settled of the two. Written reviews are what separate them: 69% of My Lisp's written reviews are positive against 64% of Code App's.
My Lisp ships an update every 6 weeks, Code App monthly. Both last shipped on September 22, 2026.
