The problem
Construction coordination is broken
Field teams and office staff struggle to stay aligned. Markups get lost, issues fall through the cracks, and nobody has the full picture.
- Email chains with screenshots
- Important markups buried in email threads that nobody can find when they need them.
- WhatsApp markups with no history
- Quick annotations in chat apps that disappear and leave no audit trail.
- BIM tools field users won't open
- Powerful desktop software that's too complex for anyone outside the office.
- Manual meeting reports
- Hours spent compiling notes instead of solving problems on site.
What you can do
Built for the people who do the work
-
Show exactly what's wrong
- Point at the problem, don't describe it. Circle it, pin it, done.
-
Never lose track of who's fixing what
- Every issue has an owner and due date. No more chasing people down.
-
Use it right on the job site
- Pull out your phone, mark it, move on. No laptop, no office needed.
-
Prove what was agreed
- When someone says "nobody told me" — you've got the receipts.
