A collection of scripts can be edited and run.  The program comes with a few predefined scripts, including a REPL server which allows starting a REPL from a remote telnet client.

The Apple developer agreement still provides that no interpreter may be used on an iOS device unless all code run by the interpreter is packaged with the app at the time it's installed, and no app is allowed to unlock or add additional features after install. I would expect Apple to reject this app on that basis.

I know of another Scheme interpreter, Pixie Scheme III for iPad, which has a "Save World" feature and which is available on the App store.  I'm not sure Gambit REPL is very much different in this respect.  Do you think the fact that you can "telnet" to Gambit REPL makes it objectionable with respect to the Apple license, or is it something else?  Perhaps the fact that Pixie Scheme III is free makes a difference.  I'm tempted to charge 0.99 $ for Gambit REPL to see if the fact that it is non-free makes a difference.
