About this app

This app lets you take photos of handouts or study materials, highlight the parts you want to memorize, and create fill-in-the-blank questions.

It's perfect for memorizing for school tests and qualification exams. It's convenient because you can create memorization questions without writing or messing up the materials.

It's completely free to use, supports importing images and PDF files saved on your smartphone, and allows you to place up to 100 markers per image.

It's focused on a simple process: ① Take a photo → ② Hide (place a marker) → ③ Remember! (open/close the marker). While it lacks complex grading and settings, it's incredibly easy to use.

◎Feature Update History
[ver1.10.0]
① Added the ability to share multiple question data at once:
In response to your feedback, we've added the ability to archive (zip) multiple questions together and share them on other devices. Previously, the sharing feature only allowed for individual questions.
... * On the list screen, select "Select" from the menu on the right side of each question card to display a checkbox. After selecting the questions you want to share, you can create a shared zip file using the share button at the top of the screen.

② Added the ability to save multiple question images at once:
In response to your feedback, we've added the ability to save multiple selected question images to your device at once.
* On the list screen, select "Select" from the menu on the right side of each question card, select the questions you want to save, and then click the save button at the top of the screen.

[ver1.9.0]
In response to your feedback, we've added the ability to display text on markers.
* In creation mode, press and hold a marker to display the "Text Settings" pop-up.
* With this feature, you can number markers, create simple notes using markers as text boxes, and create additional fill-in-the-blank questions (using the setting to display when the marker is opened).

[ver1.8.0]
◯ Added marker and question card colors:
In response to your feedback, we've added two new marker colors, white and black, and two new question card colors, blue and gray.
*Please note: If you share question data with additional colors for highlights or question cards on another device and open it with an older version of the app (prior to 1.8.0), the additional colors will not be recognized, and the markers will be converted to orange and the cards will be converted to colorless.
Therefore, please update the app on the device you are sharing to to the latest version.

[ver1.7.0]
◯ Added direct navigation between questions:
In response to your feedback, we've added a feature that allows you to move directly to the previous or next question without returning to the list screen.
On the question creation/practice screen, while in practice mode, tap the left or right button at the bottom of the screen to navigate directly.
*However, on the question list screen, you must select either "Manual Sorting" or "Date Created" as the sorting method.

[ver1.6.0]
① Added the ability to hide ads for a certain period of time:
We've added a "Hide Ads for a Certain Period of Time" option to the settings screen.
By watching an ad (video, etc.) using this button, you can hide all ads for one hour after watching.
*Since the time is measured on the server (Japan time), it may differ from the time displayed on the device.

② Added the ability to check notifications and app update information:
We've added a "Notifications & Updates" button to the Settings screen.
From this button, you can check:
- Announcements
- Update information for each version of the app


[ver1.5.0]
In response to your feedback, we've added a folder sorting feature.
You can create and select folders using the folder icon button in the lower right corner of the problem list screen. *You can move problem data between folders using the three-dot menu on the right side of each problem card.

All problem data created before the app update is saved in the "Main Folder" (the Main Folder cannot be deleted or renamed).

To simplify things, it is currently not possible to create hierarchical folders.

[ver1.4.0]
In response to your feedback, we've added a feature to manually sort problems on the problem list screen.
*Select "Manual Sorting" from the sort button in the upper right corner of the list screen, and press and hold a question card for about one second to slide it to reorder (sorting is not possible during a text search).

[ver1.3.0]
In response to your feedback, we've made it possible to duplicate and reuse markers you've created.
*We've added a "Duplicate Marker" option to the menu in the dialog that appears when you press and hold a marker in edit mode. When duplicated, a duplicate marker will be created slightly offset from the original marker and will remain selected.

We've also made it possible to change the title on the question list screen.
*You can change it using the menu button on the right side of the question card.

[ver1.2.4]
In response to your feedback, when you return to the list screen, you'll now be returned to the position where the previously opened question was displayed, rather than the top position.

*When creating or updating questions, the sorting process is affected. Therefore, the scroll position has been adjusted so that edited questions appear at the top when returning to the list screen. (If scrolling reaches its limit, the scroll position will be adjusted to display as high as possible.)

[ver1.2.0]
In response to your feedback, we've added three levels of image quality (resolution) for taking photos and importing images from your device: high, medium, and low.
*The default is low (same quality as before).
*If your original camera resolution or image file resolution is low, changing to medium or high may not make a difference.

[ver1.1.0]
The initial display size of markers can now be changed.

◎Other features include:

●A sharing feature allows you to compress questions you've created and send them to other users. You can also import questions shared by other users.

●The markers can be freely rotated, so you can hide slanted text and shapes. This makes it easy to hide even tilted photos.

●The markers can be opened and closed with a tap, making them intuitive to use.

● There are two modes: Practice mode and Creation mode. Markers cannot be edited in Practice mode, so there is no risk of accidentally moving or deleting them.

● You can zoom in and out on images by pinching in and out. This is useful for fine-tuning the area you want to hide when the text on the image is small.

● You can resize and rotate markers using the buttons at the bottom of the screen, making subtle adjustments easy.

● You can change the color of the marker, allowing you to distinguish between questions you have answered correctly and questions you want to review.

● You can display text on markers, so you can assign question numbers or use them as sticky notes.

● You can give each question a title. There is no character limit, so you can also use it as a memo field. Text entered in the title field can be searched for using the text search on the list screen (described below).

● You can save captured images to the Gallery folder on your device.

● On the question card list screen, you can change the card color to distinguish between different types of questions.

● You can perform a text search for the text in the title field.

●Question cards can be sorted manually or by creation date, update date, or title character code.

●Folders can be created and questions can be categorized and managed within them.

●Dark mode can also be switched on.
