Pretty darn good

Easy setup, Ran without a hitch, but sometimes I have to enter the IP address to get a device connected. (they make this about as easy as possible)

I like how I can get multiple devices on my computer with resizable windows, but I wish I could do the same on an iPad.
With multiple devices in iOS, I can see each divice and a preview of what the device sees, but I can only expand the veiw to see one device at a time.
On my laptop, the preview is layout better, and I can open resizable windows for each device.
Also would like the iOS version to have a preview more like the computer version. (right now in iOS they are lined up one on top of the other, and I have to scroll up and down to see the previewson various devices)

I also like how its not set up like some kind of spyware, the recordings stay on the device and are not transmitted to my computer.
You can set it up in lock mode, where the screen will go dark after a while, but when it you unlock the screen brighness is ususaly “full dark” (im guessing they will fix this)
Using a 3S, the latency is about a half second, 4S is better, and on a 5S or my gen 2 iPad, there is almost no latency at all.
I tested it with up to four iOS devices, worked well but latency did increase when there was other trafic on the same wifi hotspot.
