One Thing
Read full descriptionHide full description
Too many tasks? That's the problem. One Thing is the anti-todo app. You can only add one task at a time. No backlog. No list. No prioritization. Just the one thing that needs your focus right now. When you have 20 things to do, your brain chooses to do nothing. One Thing removes that friction. Enter a task, and it stays on your screen—in-app, on your Home Screen widget, everywhere—until you're done. Sometimes priorities change. That's okay. Long-press to "Let Go" of a task without guilt. A short pause reminds you to be intentional, not impulsive. Features: • One active task only—by design • Home Screen widget with instant "Done" button • Focus timer shows time spent • "Let Go" for tasks that no longer matter • History tracks your completed tasks and focus rate • No account, no cloud, no tracking—100% private One Thing is for people who are tired of todo apps that become graveyards of good intentions. Do less. Finish more.
