About this app

This app allows you to easily create fill-in-the-blank questions by simply taking a picture of a printout or textbook with your camera, converting it into text data, and then selecting and hiding the text.

It can also automatically generate suggested fill-in-the-blank sections using a unique logic for identifying important vocabulary.

This app was developed with the aim of reducing the time spent creating memorization tools, allowing users to dedicate more time to memorization training.

*The automatically generated fill-in-the-blank suggestions are for reference only. You can manually edit the automatically generated results. Also, there is a character limit for the question text in automatic creation mode. Switching to manual creation mode allows for unlimited characters.

You can use this app to study for school tests and qualification exams during spare time, such as while commuting. It's convenient because you can create memorization questions without writing on the material or smudging it.

It's completely free to use, and the data for the question text can be imported in four ways: by taking a photo, importing an image file, importing a PDF file, or importing/pasting existing text data.

When you import a photo, image, or PDF, the OCR function extracts the text data.

*Terms of Use*
When extracting text from images using the OCR function, you need to sign in to Google Drive with your Google account (*).
Image data is only sent to your Google Drive and not to any external servers on the developer's side, so you can use it with peace of mind.
* Google and Google Drive are trademarks or registered trademarks of Google Inc.

The app focuses on simple functions: ① Take a picture → ② Hide (automatic possible) → ③ Remember! (Open/close fill-in-the-blank marker). While it lacks complex scoring and settings features, it's extremely easy to use.

Created questions can be archived and shared so they can be opened on other devices (sharing individual questions or all questions at once is possible).

Added a function to increase the character limit to 2,000 characters when using automatic fill-in-the-blanks.
You can increase the character limit by tapping the "Increase Character Limit" button in the lower right corner of the "Create Text" or "Confirm Text" screen and watching an advertisement.

Added a function to prevent advertisements from being displayed during practice exercises for a certain period of time (Practice Focus Mode).

By watching an ad in the "Practice Focus Mode (Partial Ad Removal)" option added at the top of the "Settings" screen, you can hide ads within the practice screen and ads displayed when moving from the practice screen to other screens for 1 hour (60 minutes) after viewing the ad.

[ver1.6.0]
Added folder organization function.
You can create and select folders using the folder icon button in the lower right corner of the problem list screen.
*Moving problem data between folders can be done using the three-dot menu to the right of each problem card.
*The main folder cannot be deleted or renamed.
*To keep things simple, it is not currently possible to create hierarchical folders.

Added a function to manually sort (rearrange) problems on the problem list screen.
With "Manual Sort" selected from the sort button in the upper right corner of the list screen, you can rearrange problem cards by long-pressing them for about 1 second and sliding them.
*Sorting is not possible while performing a text search.

Added "Notifications/Update Information" to the settings screen.
From this button, you can check notifications from us, update information for each app version, etc. [ver1.5.0]
Added a feature to archive created problems and share them with other devices. This can also be used as a backup function when changing devices.
* To share individual problems, select "Share Problem" from the menu button on the right side of each problem card.
* To share all problems at once, select "Share All Problems (Backup)" on the settings screen.
* To load shared problems, select "Shared File" from the "Add New" button (+ mark) at the bottom of the problem list screen.

[ver1.4.0]
Improved the ability to directly navigate between previous and next problem screens from the problem screen in practice mode.
* Navigation is only possible in practice mode.
* In the list screen, if you have filtered the problems displayed using search terms, you can navigate within the filtered range of problems.

[ver1.3.0]
In creation mode, you can now edit the text of the selected problem (parts with fill-in-the-blanks cannot be edited; you must first disable the fill-in-the-blanks setting).

[ver1.2.1] [ver1.2.0]
* Added a function to batch delete spaces and line breaks in text during text input or after OCR text reading to improve the accuracy of the automatic fill-in-the-blank function.
* Modified the function to delete extra spaces (blanks) at the end of each sentence that occur after OCR execution.
* Fixed a bug where setting changes were not reflected after restarting the app after changing the sorting method on the problem list screen.

[ver1.1.0]
Added a function to perform a simplified (low-accuracy) OCR scan when you cannot sign in to Google Drive.
* This is a simplified function, and the accuracy of character recognition is lower than OCR with sign-in, so it is assumed that you will manually correct the text to the correct form after scanning.

[ver1.0.6]
Added an explanation on how to delete fill-in-the-blank markers, and modified the function to make the selected fill-in-the-blank marker easier to see when deleting or changing the color of fill-in-the-blank markers by making the tapped marker's color appear lighter.

[ver1.0.5]
The settings screen now features a clearer contact button for bug reports and improvement requests, and a link to store reviews.

◎Other features are as follows:

● You can easily add fill-in-the-blank markers by selecting text in the problem statement.

● Fill-in-the-blank markers can be opened and closed with a tap, making them intuitive to use.

● There are two modes: practice mode and creation mode. In practice mode, markers cannot be edited, preventing accidental additions or deletions.

● You can change the color of markers, allowing you to distinguish between problems you've already answered correctly or problems you want to review.

● You can give each problem a title. By default, the first 20 characters of the problem statement are automatically entered.

There is no character limit, so it can also be used as a memo field. Text entered in the title field, along with the problem statement text, is included in the text search on the list screen.

● Captured images can be saved to your device's gallery folder.

● You can change the color of cards on the problem card list screen to distinguish between problem types.

● Problem cards can be organized into folders. *For simplicity, folders cannot be hierarchical at this time.

● Problem cards can be sorted by manual order, creation date, update date, or title character code.

● Dark mode is also available.

● Created problems can be archived and loaded on other devices, allowing for sharing across multiple devices.
