Teams still manage signage with spreadsheets, WhatsApp or expensive software contractors hate. Signplanr is a map-based sign management platform with a mobile contractor app, so organisers track every installation in real time with photo-verified completion reports. Every sign is pinned to a map. Every contractor knows where to go. Every installation is photo-verified. Organisers place signs on interactive maps and approve with photo review. Contractors get a mobile PWA — offline, no download.
