This document outlines goals and features for a todo list app for iPhone users. It aims to provide a refined interface, clear table design, and flexibility. Key features include listing and sorting todos, viewing todos on a map and calendar, adding new todos, editing existing ones, adding photos and locations to todos, and time-limited recording. It uses the popular todo app Todoist as an example and provides mockups of the app's todo list, map, calendar, and recording screens.
