## What is Master Note?

This app is an app that allows you to write notes in a notebook format.

If it's a normal memo app,

・I can't organize well and I don't know where I wrote it down.

・It's full of notes and it's hard to look back.

Even so, if you use a notebook,

・It's troublesome to use it properly, and it's troublesome to carry it around.

・It's troublesome to look for it even if you look back later.

・It's hard to manage things that you don't want to be seen by someone.

・When it comes to the second and third books, it's hard to keep old ones.

I want a notebook that can be easily written at any time and reviewed immediately.

I made it for such a person.
