## What is One?

One-Line Diary is a simple journaling app that lets you easily capture your daily thoughts and moments in just a few words.

With the calendar view, you can look back on past entries and quickly see how many posts you made on each day at a glance.

The built-in report feature helps you review and visualize your records, making it easy to notice changes in your feelings and habits over time.

Designed with a clean and distraction-free interface, the app lets you focus entirely on your thoughts without interruption.

Why not start recording small daily insights and emotional changes at your own pace?
