NS Basic/App Studio compiles Visual Basic style BASIC to JavaScript + HTML5. Also includes an IDE. Targets iOS and Android. (http://www.nsbasic.com/app)
Wow, that's a blast from the past, from the Palm OS days. Interesting that they're still around.
NS Basic was actually around long before Palm OS, starting with the Newton. (!) We think /App Studio is our best yet.
Ah, nice! That's a long history - you've held out better than some of the other tools I remember using for Palm, like CASL, HB++ and AppForge. (Also amusing that Palm got their start on the Newton, with Graffiti.)
