Computer programs called apps are helping people avoid violence in the streets of Rio de Janeiro, Brazil.
Rio de Janeiro has an average of 15 gun battles every day.Innocent people often get caught up in the shootings.
One of the latest security apps is called OTT.That is short for Onde Tem Tiroteio, which means "Where There is a Shootout" in Portuguese.
最近有一款安全手机应用名叫OTT。是Onde Tem Tiroteio的缩写，在葡萄牙语中指“哪里有枪战”。
The app collects reports of shootings and sends the information to its users through social media services,such as Instagram, Twitter, Facebook, Telegram and Zello.

Henrique Coelho Caamao provides technical support for OTT.He told the Reuters news agency, "I keep saying, I don’t want a million ‘likes.’I only want to save lives."
His group says its news alerts reach nearly 3 million people.That number represents almost half the population of Rio de Janeiro.
Our job is not to arrest anyone, Caamao said."We don’t have a direct link to the police and drug traffickers, or whatever.Our aim is to help people avoid crossing paths with lost bullets."
Violent crime in the city rose by 11 percent in the first half of 2017, compared with the same period in 2016.More than 2,300 people were killed in the first five months of this year.
Another app that informs users of gun violence is called "Crossfire," or Fogo Cruzado in Portuguese.The app was created just before the 2016 Olympic Games in Rio de Janeiro.Its developers received financial support from the rights group Amnesty International.
Shootings take place on a daily basis, says Cec?lia Oliveira, the data manager for the app.Not a day goes by without the peace police unit recording gunfire or a shooting in some area.
Oliveira said that people provide information about street violence through social media.
Sometimes they’ll tell us: ‘I walked through a shootout just now,’ and sometimes they tell us: ‘It’s calmed down,’ she said.We have that rapport from people.The number of app users grows every day."
The app provides users with details about shootouts, such as the location, the number of people shot and other information.Since Rio de Janeiro does not keep an official list of shootings, the app helps provide unrecorded gun violence statistics.
