## What is One Task?

Too many tasks leave you overwhelmed. 
One Task is a minimalist to-do app that helps you focus on the single most important thing right now.

Nothing more. Nothing less.

Instead of juggling endless to-do lists, One Task limits you to just one main task. 
This simple constraint helps you reduce mental clutter and actually finish what you start.

You can break your main task into a few small subtasks, but you'll always know what truly deserves your attention.

Finished tasks are archived automatically, so you can look back or restore them anytime.

Got something you want to do later? Unlock Vault to stash it away without losing focus on what matters right now.

One Task is designed for people who want clarity, focus, and calm productivity.

No accounts.
No complex features.
Just one task at a time.
