About this app

With Colab, you participate in the construction of your city by indicating improvements, supporting decisions, answering queries and receiving feedback directly from your City Hall.

Colab was created to be the intermediary between the citizen and the government, using technology to provide greater transparency in the management of your city, with a community that already has more than 450,000 citizens, 300,000 publications and 490,000 responses in public consultations and surveys .

Collaborate with City Hall
Did you see a broken trash can on the street? Passed by a tree in need of pruning? Did you notice that there is garbage accumulated on your corner? Take a photo, add details in the description and publish! The City Hall can receive your demand and respond directly through the application.

Participate in decisions
Evaluate services, make suggestions and participate in surveys and public consultations. Choose the band that will play at the end of the year party, or where the new bus lanes in your city will pass, all directly from your cell phone, wherever you are.

complete missions
Exercise your citizenship in a fun way! Is your city's blood bank in need of donations? Donate blood, check in at the Blood Center, take a photo and save lives. Help the City to map possible dengue outbreaks! All this gives you points :)
