BabyGuard lets you know by phone, E-mail when your baby wakes up. The app can run on your old iPhone after you have upgraded to a newer model. We recommend using Free Family Calls or a smartphone family discount. BabyGuard calls(send e-mail) to a registered phone number(e-mail address) are triggered by any major tilt or positional change for the old iPhone, based on the accelerometer's ability to pinpoint its location in three dimensions. You can hear if your baby is crying, and respond with a parent's soothing voice. Put your iPhone in the baby's cot, and long press for START on the BabyGuard touch screen. This activates the accelerometer, which disregards data from the first 20 readings, and generates an average from the next 20 readings to define its 3D base location. Monitoring is then initiated, and it is stopped and re-initiated at one-minute intervals thereafter. When your baby wakes and stretches, the iPhone moves, the accelerometer detects the altered location, and you can be sure of getting the news with a call and receive email from BabyGuard.
