## What is 一行日記?

One Line Diary is a simple and easy-to-continue diary app designed to help you build a habit of reflecting on your day, even if just a little.
As the name suggests, its minimalist design encourages you to write just one line each day.
Even if you're busy or not confident in writing, you can easily start journaling.

Simply open the app and record a brief thought, a memorable event, or how you felt that day in a single line.
You can later look back on your entries through a calendar or list view, naturally building a personal timeline of your life.

The app features a clean and intuitive interface with no advertisements, allowing you to focus purely on your journaling experience.
It follows a one-time purchase model — no subscriptions required — so you can use it with peace of mind.

This app is perfect for diary beginners, those who want to easily keep a life log, or anyone looking to organize and reflect on their thoughts each day.
