I have used a ton of “meeting” apps. Live Meeting, Goto Meeting, ATT Web Conference, TeamViewer, etc, etc.
Best of the best? My opinion? Goto Meeting. Easy to setup, easy to use. Just works.
There is also an iPad app! I have used a couple of times and it works great. Whenever some *other* meeting software seems to fail, Goto Meeting works.
Not saying there isn’t room for improvement, but it just seems to always work. I have had to use it to step in when LiveMeeting fails, or ATT web meeting fails, etc. It is a pretty awesome product and if you have a chance to use it, I would say go for it, You won’t be disappointed.
