This is by far the best presentation app. Im running iPhone 5 and a 15" MacBook Pro. I setup a local computer-to-computer network on my MacBook and then connected to it using the wifi connection on my iPhone 5. Everyone was amazed how I controlled the ppt from my iPhone.
Do not buy the iclickr app; its 10x the price of this one. Thank god for this handy app. Saved my life today and impressed the group.
