Recurrent Notification Manager Apk
This app allows to configure recurrent notifications for each app that is using the standard Android notifications subsystem.
For each app, you can configure the ringtone, vibration, led color, number of repeats and interval of each notification.
Notifications are automatically cancelled if the monitored app removes the notification.
Also, for each monitorized app you can configure if you like to be notified when a ongoing or clearable notification was created or if the created notification contains a specific text (Jelly Bean or greater).
This app requires a special permission that needs to be activated after the install (go app settings in order to activate it).
