Description by Yongjun Lee Written by the developer, not by AppBrain. Click to read.
Tired of endless to-do lists that just get longer? Three Focus is a beautiful, simple task manager built on one powerful rule: you can only have 3 active tasks at a time.

This "less is more" approach helps you stop procrastinating, beat overwhelm, and build real momentum. By forcing you to prioritize, Three Focus helps you concentrate on what truly matters. Complete a task, and only then can you add a new one.

It's the perfect system for anyone who wants to stop planning and start doing.

Key Features:

The 3-Task Rule: Our core feature. Limit your active tasks to three to maintain perfect focus and clarity. Finish a task to unlock a new slot.

Beautiful Pastel UI: A clean, calming, pastel-themed interface that's easy on the eyes and a pleasure to use.

Full Dark Mode Support: Complements the pastel colors and works perfectly with your device's theme, day or night.

Track Your Progress: Stay motivated by tracking your weekly completions, daily streak, and total tasks finished with our built-in statistics.

Activity Calendar: Look back on your achievements and see your productive days at a glance.

Simple Task Customization: Personalize tasks with custom colors and set flexible reminders (hourly, daily, or every 2 days) to stay on track.

Stop managing lists and start completing tasks.
