THE WHOLE IDEA
To-do lists grow forever.
Your attention doesn’t.
One Thing gives the most important task a permanent place above every other window—until it’s done.
Always on top
The banner stays above normal apps, so your priority never disappears behind busywork.
Quiet history
Completed and replaced tasks are saved locally—available when you ask, invisible when you focus.
