Notification Checker is a free Android app developed by West-Hino. It falls under the Utilities & Tools category and aims to solve the problem of missing important calls or emails due to not noticing them in the status bar.

The app constantly checks the information in the status bar and notifies the user with a vibration if there are any unconfirmed notifications. This ensures that the user never has to worry about missing an important call or email again.

By default, the app checks for notifications every 10 minutes, but this interval can be adjusted according to the user's preference. When the app is launched, a list of installed apps on the device is displayed, and the user can choose which apps they want to check notifications for.

Notification Checker uses the Alarm Clock feature to accurately check notifications even in Doze mode. However, depending on the model, an alarm icon may be displayed in the status bar due to Android OS specifications. If the user does not use Alarm Clock, they need to register "Notification Checker" in the app that does not optimize battery. Some models may have their own application control settings, so it is recommended to check the instruction manual for more details.

The app requires the permission to get the list of apps in order to provide the notification checker function. It is important to note that personal information will not be sent outside the app or provided to third parties.

Please keep in mind that the developer is not responsible for any troubles or damages caused by the app.
