These conventions are great – packed full of camaraderie and animated atmosphere, but they can also be a bit bewildering. Everything’s moving at full pelt from the moment the doors open, and the floor plan looks like it was designed by dropping a handful of maggots in an ink pot and letting them wriggle around on a schematic of the venue.

This year, however, most visitors to the MacWorld Expo will undoubtedly have their iPhone in accompaniment, and with the free iMacworld app loaded, it can guide you around the dazzling world of Apple with ease.

The app is split up into three sections; Exhibitors, Products and Conference Sessions. It provides maps of the expansive venue’s layout to help you find the booth you’re looking for, and even allows exhibitors to send out live messages and alerts as to what they’ve got going on.

Sounds like the perfect companion for any expo, so let’s hope the idea catches on. Grab the app from here if you’re heading for the MacWorld Expo – your life might just depend on it (probably not, but at least you’ll be able to find the nearest loo).
