We highly recommend the cMonitor iPhone App.
It's very easy to set up, has a very clean design and is very easy to use.
Plus, it only costs $2.49!
It's the work of MotionMaster in Victoria, and everyone is saying great things about it.
“I use the iPhone app – cMonitor to periodically monitor what is happening…. the cMonitor App worked great and is also one time purchase …it was so simple to set up!”
