This page holds links to software I use. It is not completed and, for now, holds some items I want to make available.
Note: the authoring system I use is LiveCode. It is in use by everyone from elementary school to professional app developers. It is very powerful, yet easy to get started with.
There is a free open source version available. You can also get a developer's license and can sell your apps. The authoring system will generate standalone and mobile applications for Apple OSX, Windows, Linus, iOS, and Android platforms.
