Unfortunately Android doesn't have default integrated functionality to notify

the user periodically about missing calls/messages/other notifications via sound

(only LED is blinking). This tool allows you to monitor notifications from any

applications which are important for you and perform sound reminder

periodically.

Just launch app, allow it to receive notification events, select reminder

interval and important applications. That's it. If there are any unhandled

notifications from thet selected apps in the statusbar, app will notify you

periodically with the notification sound you choose.

The battery is used only if there are missed notifications which requires

periodical reminder. App wakes phone to perform sound notification and then

sleep again.
