Here comes the decription
Smart Reminder is a small tool which resides in the background. It can be set to be automatically lauched when system starts. Its main task is to remind you about received SMS messages and faxes waiting in your Inbox and missed calls.
Smart Reminder is highly customizable. You can set its 'working hours' and choose a WAV file to be played as a reminder tone. It can be invoked to the foreground anytime using a defined hotkey to change the settings or enable/disable it.
Greetings and have fun!
