This is one of my favorite of the applications that I have written. It is one that I use more on a daily basis when I use my Newton. This application supports keeping a variety of checklists on your Newton. I use it for instance to keep my list of things to pack for a trip. I can check off which items to bring on this particular trip and then make that list into a new list. I can print, fax, mail or beam that list.
Checklist requires an Apple Newton and a Mac or PC with Newton Connection to download it to the Newton.
