As iOS developers will know, it can take a while to get a new iPhone app approved, with one online tracker showing that the average time is currently around ten days. The developers of a free app enabling people to express support for the Je Suis Charlie campaign following the terrorist attack in France didn’t want to wait. French news agency Nice-Matin emailed Tim Cook to request an expedited review, an assistant replied ten minutes later promising a review within the hour, and the app is now online.

Literally translated as “I am Charlie,” the phrase voices support for freedom of speech and a refusal to be silenced by terrorists …

The I Charlie! app is a simple one, allowing you to add your location to a map, indicating your support for the campaign. While it’s primarily aimed at those in France, the developers say they hope that iPhone users in other countries will also join the campaign.

Apple added a Je Suis Charlie footer to its French website in the wake of the attack, and Google recently donated $300k to help the Charlie Hebdo magazine achieve a 1m print run in its next edition.
