The gutterbarometer, brought to you by Creative Social and Dare, is the must have accessory for Cannes next week. Updated from 2010 with the added Carlton Terrace as well as the Cannt bar in London (more to follow on this), the gutterbarometer will track your GPS location and give you points as you spend time at the Gutterbar, on the Carlton Terrace or in London at the Cannt Bar.

Just download the app and sign in with Twitter. Done. We will be reporting the winners after Cannes and may even see if we can get some of our sponsors to provide us with some suitable prizes.

Hope to see many of you in Cannes. If not, do be sure to check the blog and twitter as we will be reporting live throughout.
