Simple Task Manager - One Task
To Do List for Better Focus
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Too many tasks and not sure where to start? One Task helps you focus on one thing at a time. Break it into simple steps with AI and start making progress.
Too many tasks. Too many lists. Nothing gets done.
One Task is a simple, minimalist task manager built around one idea: focus on one task at a time.
Instead of filling another endless to-do list, One Task lets you set just one main task. No overwhelming backlog. No constantly changing priorities. Just one clear thing to focus on right now.
Do one thing. Finish it. Then move on.
■ FOCUS ON ONE TASK
You can have only one main task at a time.
This simple constraint removes the question of “What should I do next?” and helps you stay focused on what matters most.
■ BREAK BIG TASKS INTO SMALL STEPS
A task can feel overwhelming when you don’t know where to start.
Break your main task into up to 5 smaller, actionable subtasks and tackle it one step at a time.
■ AUTOMATIC TASK ARCHIVE
Finished a task? It’s automatically moved to your archive.
Look back at what you’ve accomplished or restore a previous task whenever you need it.
■ SAVE IT FOR LATER WITH VAULT
Thought of something else you need to do?
Put it in Vault instead of interrupting your current task. Save ideas and future tasks for later while keeping your attention on what matters right now.
■ AI SUBTASK BREAKDOWN
Not sure how to get started?
Enter your main task and let AI break it down into clear, actionable subtasks. Choose only the suggestions that make sense for you and add them with a tap.
Free users can try AI Subtask Breakdown once per day.
Subscribe to AI Subtask Breakdown to increase your subtask limit from 5 to 10, for both AI-generated and manually added subtasks.
ONE TASK IS FOR YOU IF:
• Your to-do list keeps getting longer

One Task helps you focus on fewer.
Stop managing everything.
Start finishing one thing.
One Task — one task at a time.
No accounts.

Just one task at a time.
