About this app

WHAT DID YOU DO WELL TODAY?

OneLineToday is a simple journaling app where you write just one line about something you did well today.

If keeping a long diary has always felt overwhelming, start with just one line.

◆ NOT A GRATITUDE JOURNAL. NOT AN EMOTIONAL DIARY.

OneLineToday is different from typical diary and journal apps.

A gratitude journal focuses on what you received from others.
OneLineToday focuses on what you did.

It doesn't have to be anything extraordinary.

You washed the dishes you had been putting off.
You stayed calm instead of getting upset.
You simply made it through the day.

The things we often overlook may not be small after all.

◆ ONE LINE A DAY MAKES JOURNALING EASY

You don't need to write a lot.
You don't need to write perfectly.

Just one short line is enough.

Because it's simple, it's easier to keep going every day.

Start each day with a different inspiring message and leave your own line for today.

A daily writing habit grows naturally, one line at a time.

◆ ONE LINE BECOMES A BOOK

Each line becomes a page.
Pages become chapters.
Chapters become a book.

Your personal library slowly fills with the story of your life.

On difficult days, you can open those books and see proof of how far you've come.
