Do One
Focus on what matters today
Free · In-App Purchases · Designed for iPad
One task. One time. That's it. Do One helps you cut through the noise and focus on what truly matters. Stop managing tasks. Start finishing them.
Stop adding. Start finishing.
Most productivity apps help you manage more tasks. Do One helps you do less — and actually get it done.
Every day, Do One asks you one simple question:
"If you could do just one thing today, what would it be?"
Pick your ONE. Focus on it. Complete it. Reflect on it.
That's the entire system. No complex project boards. No overwhelming task lists. No guilt-inducing backlogs. Just one thing that matters, every single day.
HOW IT WORKS
• Choose — Select your most important task for the day
• Focus — Your ONE stays visible on your Home Screen widget
• Complete — Mark it done when you finish
• Reflect — Review how your day went with a quick check-in
WHY DO ONE WORKS
The problem isn't that you don't have a task manager. The problem is that you have too many tasks and can't decide what matters most. Do One solves the priority problem, not the management problem.
