Relax comes with a built-in environment called Forest Stream Pro, a digitally remastered version of the original. Relax lets you add other great environments to the program by purchasing one or more of the Relax Environments. There are six to choose from. Relax uses the Mac OS Navigation Services, so finding your favorite environments is easy, and with the Environment Construction Kit, you can make your own environments. The kit comes with every copy of Relax, absolutely free. For more detailed information, including on updates, please read the documentation or visit the home page.
