BART Watch: Free Security App for Riders. The BART Watch App offers the public a quick and discreet method for reporting suspicious activity directly to BART Police. The app can send pictures, text messages, and locations of suspicious people or activities. From the home screen, users have two easy options for contacting BART Police: * The “Report a Problem” button allows users to send text or photos directly to BART Police. To ensure discretion, the camera flash is automatically disabled when photos are taken through the app. When reporting an issue, users can select locations and report categories to assist BART Police. Riders can also send reports anonymously if they chose. * The “Call BART Police” button will connect customers directly to BART Police. The application is designed for BART. If you send a report in an area without cellular connectivity, it will be stored and sent when connectivity returns. The system is also designed to send text messages before pictures so that BART Police can get app reports as quickly as possible. Additional Features BOLO (Be On the Look Out) Alerts. BOLO Alerts on the BART Watch App may display alerts from BART Police about specific persons of interest. For example, BART Watch may display information about a missing person or child, such as where they were last seen. If you see a person from a BOLO, immediately call 911 and send an app report to BART Police discreetly. Help keep BART safe, "See something, Say something."
