ScrapBook is a note-taking application for Palm OS, featuring enhanced organizational and search capabilities that help you manage a large collection of notes. ScrapBook also supports encryption (using the DES algorithm), to let you keep selected notes private.
You can organize your notes using nested folders (as many as you need, nested as deeply as you need), as well as by using standard Palm OS "categories". Also, you can assign a list of keywords to a note, and find notes by searching for one or more keywords.
ScrapBook can search its database for multiple words or strings at once, searching keywords, titles, and (optionally) full message texts. This includes the ability to search encrypted notes (prompting for passwords as needed)! Search results are sorted so that the best matches are presented first.
ScrapBook can exchange notes, in both directions, with the built-in Memos or Memo Pad application.
ScrapBook is distributed as a .zip format compressed archive, containing ScrapBook.prc + documentation (including a complete user's manual).
ScrapBook is shareware, with a 30-day trial period.
