Nag is a simple program designed to do two things well:

1. If you receive a phone call or a text and don't respond Nag will remind you with the sound of your choice and/or vibrate at an interval specified by you.
2. It allows you to quickly and easily silence your phone for anywhere from 5 minutes to 10 hours. At the end of that time, if you have received any calls or texts it will let you know as above.

The program defaults to 1 minute intervals and a gentle tone for 1-1/2 seconds so there is no need to do anything once the program is installed but you can control the tone, volume, vibrate on/off, tone frequency and length and whether to notify you on phone calls, texts messages, or both.
