SAIP users not at games will also be able to see alerts in up to eight geographical areas, letting them keep tabs on games that friends or family may be attending. The notifications or alert screens will arrive less than 15 minutes after the attack, according to the Ministry, and let you share them to social media. The app is now available for Android or iOS, in both English and French.

France is still under a state of emergency following the November attacks, and the US issued a travel warning for all of Europe. In addition, the UK Home Office warned of a "high threat for terrorism" at the games, though both governments said the warnings were not based on specific intelligence.

The warnings and alert app itself make the prospect of attending Euro 2016 a bit scary, but France is doing all it can to keep the games safe. According to the Guardian, the nation is deploying over 90,000 security staff to protect fans and players, including 42,000 local police, 30,000 gendarmes, 10,000 soldiers and 13,000 private security staff. In addition, France has rehearsed disaster scenarios for several months, staging a chemical gas attack, suicide bombing and 30 other potentially dire scenarios.

Following embarrassing lapses in security during games last month, EUFA and the French government have tightened security procedures. There will now be body searches, ID checks, and a very conspicuous police presence both in stadiums and "fan zones," where as many as seven million supporters will watch games on Jumbotron-type screens. Despite the danger, Prime Minister Manuel Valls says France is determined put on a good show. "The matches are of course all going ahead and the fan zones are maintained. Why? Because it's very important at a time of threat to show that life goes on."
