153 Cidadão is a dynamic mobile application designed to enhance public safety and community engagement by offering direct lines of communication between citizens and their local Municipal Guard units. The platform allows swift creation and reporting of complaints, ensuring that issues are addressed promptly by the relevant authorities. A standout feature includes accessibility to essential useful and emergency contact numbers with just one click, streamlining the process of getting help when needed.

Moreover, it keeps users informed with real-time news updates about significant events related to the Municipal Guard in their city. In urgent situations, the 'PANIC' function can be utilized to request immediate assistance, and for those in domestic violence situations, the 'MARIA DA PENHA' button provides a quick way to seek help, although these features do require authorization from the Municipal Guard.
