Essential if you use the Fuze service
Love this app for its ability to instantly set up a conference call right now ... faster than any web front end because you can use your Address Book data to grab peoples phone numbers and have Fuze dial out to them. I have sat on multi-person conference calls w/ lousy audio using other services and used the app to restart the call on Fuze in no more than a minute. Its nice that you dont even have to use the iPhone for the call -- it can just act as the controller while you use, say, a speakerphone for the audio.
I actually dont use it so much to manage or view currently running meetings, although that has proven handy and works fine.
You CAN schedule a meeting in the future (despite what some other reviews report) -- under "my meetings," click on the edit button, then the +. This too is faster then the web front end ... you can set up a meeting right while youre talking about it.
