On Wednesday, the French government launched a smartphone app in advance of the Euro 2016 soccer tournament. Its purpose: to alert fans of any terrorist attack that might happen and how to stay safe.

Called SAIP (Système d’alerte et d’information des populations), the app was developed in the wake of the Nov. 13 attacks on Paris, which left 130 dead at restaurants, cafes, and a concert hall.

The Euro tournament begins Friday at the Stade de France, the same venue where Islamic State militants detonated suicide bombs in the November attacks. Officials in France fear the month-long tournament – slated at venues in 10 cities across the country – might be subject to another attack.

After his arrest, Mohamed Abrini – a member of the Islamic State-affiliated terrorist cell that orchestrated the March attacks in Brussels – told investigators that the group’s ultimate target had been Euro 2016. Suspicions remain high.

The app – available for free download on iOs and Android in both French and English – will rely on geolocation technologies to send alerts within 15 minutes after an attack is confirmed. Those who download the app will also be able to view alerts for different areas, should they wish to monitor the status of family and friends elsewhere.

The app will “keep the public up to date with what we know,” Bernard Cazeneuve, France’s interior minister, told Agence France-Presse. The platform should also allow authorities to broadcast only verified information, as well as to communicate with civilians in the event that phone networks are down.

After the tournament, the government plans to use the app to continue providing people alerts about other future risks.
