I wrote Check On Me to monitor the activity and movement of my droid and if it stops moving during times that I should be awake, it will send a text to a number you input asking them to check on you to make sure you are okay. I wrote this because I am alone with my three year old daughter half of the week, and if something were to happen to me, she wouldn't know how to get help. It allows you to set your sleep/awake times, as well as what days of the week to stay active. Search the android market for Check On Me if you're interested. Thx!
