At the Under the Radar conference this week, Iotum announced its Calliflower app for the iPhone. Essentially, the app is an extension of the Calliflower desktop conferencing service, which is similar to DimDim, GoToMeeting and WebEx. With the app, you can share documents, moderate multiple parties on the call, invite guests, chat, and post images, among other things. Founder and CEO Alec Saunders gave me a demo.

The service is free and will be available on the iPhone App store soon. But starting January 1st, the app will cost $10 to download. The overall desktop and phone conferencing application combo is compelling.

And, the user interface is pretty nice, despite the fact that managing people and documents on a little screen may seem a bit crowded. Iotum started in 2004, with $2.5 million in seed funding. The company is currently seeking to raise $5 million in a Series A round.
