Alert Me Pro is a utility that transforms your iPhone into: a baby monitor, a house alarm, a car alarm, your watchdog, etc.
Alert Me Pro is very customizable and can be used in various situations.
This is how it works: Major function is listening. If the noise level goes higher than predefined by you, the alarm goes on.
You can select from multiple alarms including House Alarms, Sirens, Dog Barking, Scary sounds etc
Instead of the alarm, this app can also dial the number. For example to use as a baby monitor, it's enough to enter your phone number and leave the iPhone close to the sleeping baby.
