Offline-first scheduling that never drops your gigs, even on dusty job sites.
On-site construction freelancers can't reliably manage multiple gigs due to clunky scheduling tools that fail offline.
BuildSlot lets construction freelancers create, edit, and manage multiple gigs entirely offline via a mobile PWA. Schedules sync seamlessly when back online, with conflict detection and drag-and-drop rescheduling. Say goodbye to clunky apps that crash without WiFi.
