Radares Saltillo is a free Android app that helps drivers detect speed radars located in the city of Saltillo, Coahuila. This app is the perfect copilot for drivers, as it shows the location of all of the 22 radars installed near your exact location on a map, and alerts you with an audio alarm when you are 300 meters or less away from a radar. The app requires an internet connection to display the map, and it is connected to your GPS for faster and more accurate location.

To use the app, you need to install Google Play Service to display the maps, turn on the location on your cell phone, and select the "navigate" option for second background operation. When you are at risk of getting a ticket, the alarm will sound, and the area where the radar is located will turn red, with a 300-meter distance to decrease your speed.
