Just discovered an application that provides real time updates on news and events related to Paris. Free and compatible with iPhone and Android, it offers news on cultural events, directions to places of interest and important news (including métro and RER delays). SO far it seems to be living up to its name of giving Paris up to the second, and it worth the sacrificed bytes of space sacrificed from your mobile device.
App name: Paris à la seconde
Language : French
For Android and Iphone
