Why Siteward exists
The problem
Site information lives on paper, in camera rolls and in end-of-day emails, so the office learns about delays, snags and safety issues too late.
The product
Siteward puts daily reports, snags, permits and safety checks in an offline-first app, with voice notes turned into structured reports.
Built for: Contractors, site managers, supervisors and field crews.
- Daily task list tied to the programme
- Voice notes turned into structured site diaries
- Snags pinned to drawings with photos
- Permits to work with mandatory checklists
- Offline-first with background sync
- Safety scores and audit-ready records
