Simple Task Manager

Read full description

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 • Too many tasks make it hard to decide where to start • You want a simple task manager without unnecessary complexity • You struggle with procrastination or task overwhelm • You want to focus on one thing at a time • You like breaking big tasks into smaller steps • You want a cleaner way to manage work, study, or daily tasks • Traditional productivity apps feel like too much work Most task managers help you manage more tasks. One Task helps you focus on fewer. Stop managing everything. Start finishing one thing. One Task — one task at a time. No accounts. No complex features. Just one task at a time.
