DoOneThing - Single Task Manager

By Adam Mathes

Open the Mac App Store to buy and download apps.


Instead of being a source of constant distraction, your computer should help you accomplish what's most important to you every day.

It's easy to spend hours sitting in front of a computer immersed in doing little things, while avoiding the most important one.

DoOneThing won't nag you, or beep at you, or harass you.

Its presence at the top of your screen in a place of primacy, near the time, is intended to bring your focus back to what is most important for the day, to make your primary goal present in your computer screen and life.

What's New in Version 2.1

Bug fixes, dark mode support, icon change

Customer Reviews

escaping computer hypnosis

Thank you for this app. I appreciate being reminded that my time is valuable and not to spend it mindlessly lost wandering the internet. I love the internet, but I do not want to live there.

Perfect for MITs

I use Todoist for typical task management, but this is perfect for setting my daily Most Important Task and keeping it visible across applications.

Thanks for the update

Dark mode looks great
