[For First-Time Users]
* This app is a "widget."
It will not work simply by installing it; you need to add it to your home screen separately.
Tapping the app icon will display the "Getting Started" screen; please follow the instructions there.
From this screen, you can access the developer's website.
Please refer to it for information on settings for widget operation and any limitations.
* Please utilize templates.
The initial widget is a blank state with white text and a clear background.
By applying a theme via Settings > Widget Appearance > Templates, you can quickly set different colors for each day of the week.
The settings screen can be accessed by tapping the widget on the home screen > tapping the gear icon on the current date and time screen.
* When the date and time do not change.
Please refer to the developer's website mentioned above for troubleshooting steps.
[Special Notes]
* Regarding the "Notification Access" permission:
To ensure smooth updating of date information, the app uses the Android system's notification service for synchronization. The sole purpose is to obtain synchronization timing; it does not access notification content.
As long as "Allow access to notifications" is ON on your Android system, it will work. Excluding access to each element (real-time, conversation, notification, silent) (by unchecking the checkboxes) will allow for safer use.
*The specifications for each element may vary depending on your Android version.
