About Simple Scheme
Ever been away from your computer and thought, "Boy, I wish I could be writing Scheme code right now"? Well, now you can! Simple Scheme is a Java/Android implementation of a Scheme-like programming language and syntax highlighted editor.
It includes implementations of most features found in traditional Scheme (e.g., definitions, let, let*, letrec, if, cond, lambda, lists) with a very similar syntax. Because it's implemented in Java, we use long and double types to represent numbers, e.g., 2/3 does not have an exact representation.
Simple Scheme also includes an implementation of image functions similar to Racket's image module (http://docs.racket-lang.org/teachpack/2htdpimage.html).
See http://bryanchadwick.com/simplescheme/ for documentation and examples.
Enjoy!

App History & Updates
What's Changed
Added support for simple macros (define-syntax and define-syntax-rule) and updated the documentation. See:
http://bryanchadwick.com/simplescheme/index.html#macros
Let me know if you find any issues/bugs (sadly, I'm sure there are some).
Also fixed an end-of-file parsing issue and added a new setting for a text-based load dialog, for anyone that can't get a third-party file explorer to work.

Input is a bit annoying, but it's *less* annoying than any other code input I've tried, so points there! One request: could you implement optional function parameters, please? --- Noticed a few bugs. Calculation of the screen size doesn't seem to take into account the size of the header at the top of the screen, so images overflow the bottom of the screen. Also, parse error occurs when the last line of a file is a one-line comment.

I use it to try programming code that I'm thinking about. I saves all you do in case you forget what you did.

So far looks the most useful among the other scheme apps as it can save/load files. Thanks to author.

Good for syntax-highlighted Scheme coding I guess...but nothing will run in the REPL? Not even simple primitive calls like add1 or cons. And what good is coding if you can't test? Please fix as I would love to change my rating! Also this is more of a minor note, but it would be nice if the editor auto-indented to the correct depth after a new line.

(define (conv0 acc s base) 0) (conv 0 "42" 10) is enough to repeatably crash on my S5.

Amazing, now I'm able to hack away on the go :) Just one thing: I can save to the SD card but not read from it. I'm guessing it's because of the new changes in kitkat. Hopefully this gets looked at soon.

Just a nice toy if you're bored and want to screw around with a functional language on the go.
