There are lots of ways to get things done. With OneThingToday you simply assign a single task or project to each day. This helps you focus on one major goal each day, avoiding the distraction of other pending tasks or ongoing projects. Plan your time in Calendar mode, which gives you an overiew of one or several weeks. Once you have your time mapped out, switch to Sticky mode which displays only the task you have assigned for the current day.

Is OneThingToday for Me?

OneThingToday is designed to make managing your tasks as simple as possible, without micromanaging your time.

OneThingToday is designed for people who have multiple simultaneous projects, and can enhance their productivity by focusing on one project each day.

OneThingToday is also designed for people who only have time to tackle one task each day, and who find themselves overwhelmed by all their pending tasks in their limited time.

OneThingToday is not a traditional Task Manager, and is not an implementation of Getting Things Done®.

How do I use OneThingToday?

Using OneThingToday

Using OneThingToday is easy:

  1. Plan your time in Calendar mode
  2. Switch to Sticky mode to get work done

⌘-T: Go to Today

⌘-R: Move calendar one week earlier

⌘-Y: Move calendar one week later

⌘-.: Switch between Calendar and Sticky mode

Can OneThingToday Handle More than One Task/Day?

As the name suggests, OneThingToday is designed for one task per day. However, there is nothing preventing you from assigning multiple tasks to any given day.
