The "Memo Map" app was created to free you from the worries of "losing" and "overwriting" that are inherent to digital memos. It's a revolutionary notepad app that automatically "stores" all the steps of your note-taking, allowing you to revert to any previous point at any time.

No more fear of rewriting or making mistakes.

Why "Memo Map"?

Typical note-taking apps only save the most recent version. The moment you press the "Save" button or the autosave function kicks in, any text written before that is lost forever.

However, writing and coming up with ideas is a constant process of trial and error. You write, erase, erase, and rewrite. It's often during this process that important hints and expressions that should have been saved are hidden.

This app is more than just a text editing app. It's an "archive tool" that preserves the history of your thoughts. We've incorporated version control systems like Git into an intuitive interface that anyone can use.

Key Features and Functions

1. Automatic Backup System "Archive"

Every time you edit and save a note, the app stores a snapshot of that note's current state in the "Archive (folder)" with the touch of a button. No special operations are required.
Simply write your notes as usual, and behind the scenes, our reliable writing assistant will continuously record the "history" of your writing.

2. Intuitive "Version Restore"

If you ever feel like you messed up, you can quickly go back to the past.
When you open the "Version Management" screen, your edit history is displayed as a list.
Simply press the "Revert to this version" button to instantly restore the current note to its original state. No complicated operations or specialized knowledge are required.

3. Complete Protection from Accidental Deletion and Overwriting

Don't worry if you accidentally delete something by selecting "All" or your child accidentally erases your notes on their smartphone. Since history data is stored independently, even if the current screen goes blank, you can restore the state from a few seconds ago using the history.

4. Secure Local Management & Cloud Integration
*Cloud integration is currently under consideration. As of December 23, 2025
We prioritize privacy, so basic data is securely stored on your device (using a Hive database). You can also use Google Sign-in to store your learning records, settings, and more in the cloud (under consideration). Important ideas, diary entries, and private drafts are all managed securely.

Commitment to Security and Privacy

Notes written within the app are yours alone.
The app development team places the utmost importance on protecting user privacy.

Data Ownership: The contents of notes and history data are stored on the user's own device (and in cloud storage if authorized by the user). The developer will not view the content without permission.

Advertisement Display: Advertisements are displayed to maintain the app, but are placed carefully so as not to interfere with your writing.

Data Protection Note: To protect your data from loss or theft of your device or unauthorized access by malicious third parties (such as local hacking), we strongly recommend using a password lock or biometric authentication on your device.

Disclaimer

Please be aware of the following when using this app.


- Data Management Responsibility: While this app provides a history storage function, we assume no responsibility for data loss or leakage due to unexpected system malfunctions, device failure, or unauthorized access by third parties (such as local hacking). Please regularly back up important data to an external storage device.
- Service Use: The development team assumes no responsibility for any direct or indirect damages (e.g., emotional distress, business losses) arising from the use of this app.

5. The World of "Books" and "Book Covers"

Rather than a tedious data management system, we've focused on a design that encourages attachment to the app.

You can give your notes a title (cover). Finding the right note is as intuitive as choosing your favorite book from a bookshelf. Even those who aren't good at organizing their notes will find it easy to manage.

Useful in the following situations

This app provides peace of mind in all situations, from casual everyday notes to professional writing.

[For Creators and Writers]

Perfect for writing novels, blogs, lyrics, screenplays, and more.
It's common to find yourself thinking, "I thought the previous expression was better" during the revision process. With this app, you can make bold deletions and changes to the structure without fear. If you don't like the result, you can quickly revert to the original version.
You can access all your previous drafts in a single memo without having to separate files like "1st Draft" and "2nd Draft."

[For Businesspeople and Students]

Perfect for drafting minutes, reports, and speeches.
The panic of accidentally deleting text during an important meeting is immeasurable. With "Memo Map," you can quickly resume from the most recent save point even if the app freezes or you accidentally lose all your content.

Also, when brainstorming ideas, early, rough ideas can sometimes be useful later. By tracing back the history, you can get hints that will help you get back to your roots.

[For Developers and Programmers]

It's also useful for managing code snippets.

I use Git on my PC, but when I jot down small pieces of code on my smartphone, the lack of version control can be inconvenient. With this app, you can manage your code's change history at your fingertips and quickly revert to the state before a bug occurred.

[For Preventing Accidents in Everyday Life]

For shopping lists, to-do lists, password reminders (please manage confidential information at your own risk), etc.
The history feature instantly solves the mistake of deleting a completed item only to discover it's still necessary. It's also effective for managing frequently updated notes, such as shared family items or address books for New Year's cards.

[As a Diary/Life Log]

Have you ever scribbled down your emotions for the day, then calmly revised them?

A neatly edited diary is great, but the raw, raw emotion you felt before the edits is also an important record. By going back through your history, you can rediscover your true feelings at the time.

Simple and Easy to Use

Multi-functional apps are often thought to be difficult to use, but "Memo Map" is designed to be as simple as possible.

1. Write: Open the app and write your note as usual.

2. View: The note list screen displays "covers (titles)." Tap the note you want to view.

3. Restore: If you need to make a change, simply select the date and time you want to restore from the list of past notes and click "Restore."

With just these steps, you can achieve the ultimate risk management.
Even people who are not familiar with IT or elderly people can use it smoothly, thanks to the peace of mind that comes from knowing that they can go back if they make a mistake.
