I don't know about you, but the pressure to reply quickly to every text message I receive can sometimes overcome me. I know some people who get angry with me if I don't get back to them within 2 minutes of sending their message, and this drives me crazy. Step forward SMS Machine, a wonderful application that can respond to messages and calls automatically.

The program runs transparently on your device, intercepting any calls or messages you receive and sending the perpetrator a predefined SMS message. This makes it ideal for letting people know when you're unavailable because you're in a meeting, a library or a cinema, without disturbing the people around you.

The great thing about this program is that it's so customisable thanks to it's rule-based method of operation. Hence, you can set it to allow calls from certain numbers, schedule messages by time and date, and filter numbers that should be watched out for.

If you hate having to interrupt your activities dealing with incoming calls or messages, SMS Machine provides the perfect way to delay the need to respond.
