Great to see Gambit Scheme here

Gambit is an excellent implementation of the programming language Scheme (a flavor of Lisp) that I have used for years. Scheme is a very expressive (near) functional programming language that is clean and easy to learn. You won't be able to write large programs using the iPhone version, but this app will be useful for writing small mathematical functions and experimenting. The controls are still a little rough -- I could not find a way to go back to the script editor from the interactive prompt short of restarting the application. Hopefully additional releases will smooth out some of these issues.

Helpful keyboard but otherwise disappointing interface

The custom keyboard that comes with this build of gambit-c is very useful, making most needed keys readily available. However, the file editor is rather awkward and basic, and the REPL is far more primitive than what comes with PC builds.

If you want to try the Scheme language on your desktop or laptop, definitely try out Gambit; it is one of the most well known and mature implementations and has a great interactive REPL. This mobile version was disappointing.

This new release has fixed crashes on 64bit devices. It now works great on my iPad. Thank you.
