Im not a developer, but I sometimes get good ideas for apps.

Auto Answer Machine (AAM)

This app could work with a status changer and a list. Say I go to GYM and I choose in the AAM "GYM" and when Im working out I dont like to be disturbed, but I need to tell my people (like my GF) that I'm busy, where I am and that will call back as soon as when Im done, but if it's an emergency I can be notified too.

Every people in my custom list will get my custom message when they call me and I dont answer. If my girlfriend just calls me to chat a bit, she will get a message SMS "At GYM, will call you when I'm done", the phone could also go in silent mode depending on each status (customizable). But if she needs me urgently the ringtone could change to another one, to let me know she needs me. The phone could know its urgent if she calls me two times in less than 2 minutes.

People not in my list won't get any message, but the status will make the phone go silent or beep dependin on the ocassion.

So any developer wants to get this done? i will be the first one to donate/buy when available.
