+1000 for Ken's app. I was a die-hard IP cam viewer user (and like Rober Chau's support for it), but once I learned that you can go full screen on a single camera by holding on the camera you want on the index view, it' obsoleted any other viewer.
Besides, if there's an issue and no one here can resolve it, you send an email to Ken, and within a day or two he's got a solution. I don't think he actually does the app development. Each time I've sent something to him about the app, he replies with, "I'll pass this on to the app developer"... FWiW.
Recently I had an issue where click and holding on a given camera in the index view opened the camera above the one I was selecting. I sent an email to Ken, and 2 days later there was an update issued resolving it. Turns out if the notification/status bar is shown (by default it's set to "show always") it move the touch input down by the width of the bar. You can manually set it to "never" under the app's settings - and that's what I did to resolve it immediately. Still, Ken had an update pushed out that changed the default setting to 'never show'.
All that for a one-time payment of $10 must be the deal of the century.
