With the exception of the lack of popup keyboard,
it's already so much better than tryapl it's not even funny. :-)
In related news, I've been thinking about how to best
handle APL input on Android. I think this project screams for
an Android port just about now.
The rest of the work in getting the Android version running
(porting the APL interpreter itself) should be fairly trivial.
The difficulty is getting the input right, and I'm not really
a fantastic mobile designer. Anyone on this list who has had
any thoughts around this?
