Overview
One Big Thing is a simple daily todo app that helps you focus on what matters most each day. The app encourages you to identify one primary task and optionally add a few smaller supporting tasks.
Philosophy
The app is built on the principle that focusing on one significant task per day is more effective than managing overwhelming to-do lists. It implements a variation of the "1-3-5 Rule" - tackle one big thing and potentially a few little tasks.
How It Works

- Supporting Tasks - Add a few little tasks you might also want to get done
- Check Throughout Day - Use the app to stay focused on your goals
- Fresh Start - Next day provides a blank slate to refocus
- Minimal Complexity - Dead simple interface with "just a light sprinkling of delight"
