Urbidata: report management for any organization

A platform to receive, assign and resolve reports from a community. The person reporting marks the location on the map and attaches photos. The responsible team handles each case, and managers see response times and results on dashboards.

  • Reports located on the map
  • Photos, video and voice notes as evidence
  • Assignment, status and follow-up for each case
  • Dashboards by zone, category and response time
  • Email, push and WhatsApp alerts
  • Your own branding: logo, colors and subdomain

Categories, workflows, roles and branding are configured for each organization.
