For situations such as 10 minutes on the train or 60 minutes between meetings, you want to set the device to silent mode (vibrate) for a specified number of minutes, and then automatically return to normal (sound and vibration) after that.
You can easily call up frequently used settings as shortcuts.
*To cancel earlier than the specified time, tap the notification or create a shortcut with 0 minutes to call it up.
Permission details
Vibrate: Used for vibration operation for feedback
Create shortcut: Used to create shortcuts with specified content
Internet connection and access: Used only to display advertisements
Notes
The timer is started using a system event, so it can be operated even if it is stopped with a task kill app, but it may not be executed at the specified time on devices that enter deep sleep where system events do not occur.
For devices without a vibrate mode, silent mode will be selected.
If you reboot while it is running, the cancel event will not be generated.
Restrictions due to compatibility with Android 9 to 15
・Since Android 14, users can clear notifications by swiping (processing continues)
・Feedback after a period of time is no longer provided
