I need something like an organizer .... something I can write appointments/dates/grocery lists into. is there a title on NDS that you can use for this? with a calendar and what-not?

 

Yup. DSOrganize is the way to go.

It has a calender, day planner, adressbook, todo list, scribble pad (paint-like thingy), browser (for files on your flashcard), calculator, IRC and a web browser (quite basic though). It also has a homebrew database, has plugin support and it can open quite some filetypes in the browser. Just try it, it's my favorite piece of homebrew!
