Wow, this is great!

Of the 300 apps I have, this is the first one that I have reviewed. This is
by far, the most useful app I have, and it works GREAT! I use it with my
home automation system (Vera Prowl Plug-in) and it alerts me via Push
Notification when someone approaches the front door or side entrance via
motion detection. Not only does it alert me, but I can assign a different
alert tone depending on the alert. I hope the developer will add ring tone
sounds that can be used instead of the limited tones available in the app.
The alert also launches my security camera app which lets me see who is at
the door before I open the door or while Im away. This is a truly a useful
Push Notification app. I have 3 iPads, 1 iPod and 2 iPhone 4S phones, and it works great on all of them!
