Snagging app
Snagging lists that builders actually act on.
Over 200,000 new homes are built in England every year. Most have between 50 and 150 snags. If you're still scribbling on paper and emailing spreadsheets, there's a better way.

Why it matters
The pen-and-paper snagging list is dead.
Photograph and annotate on site
Take the photo, draw on it, add a note. The builder sees exactly what you mean — no "the scratch near the thing by the window" ambiguity.
Numbered, structured reports
Generate a clean PDF with every snag numbered, photographed, and prioritised. NHQB-ready format that builders and warranty providers recognise.
No more lost photos
Every photo is linked to its snag, with annotations and notes. No more scrolling through hundreds of camera roll images trying to remember which crack was where.
Share with your builder instantly
Email the PDF or send a live link. The builder sees the list in their browser — photos, annotations, status. They can work through it without installing anything.
Built for how snagging actually works.
Whether you're a homeowner doing your own new build snagging inspection, a professional snagger working through NHQB guidelines, or a building surveyor adding snagging to your services — the workflow is the same. Walk the property, find the defects, document them clearly enough that someone else can fix them.
Site Audit Master turns your phone into a proper snagging tool. Photograph each defect, draw on the photo to mark exactly what needs attention, add a description and priority level, and move on to the next one. When you're done, generate a branded PDF report with every item numbered and illustrated. The builder gets something they can actually work from — not a vague email with twenty unlabelled photos attached.
The app works offline, so basements, utility cupboards, and new builds with no broadband yet are all fine. Everything syncs when you get a connection. And because the report is structured, it's easy to track what's been fixed and what hasn't.
How it works
Four steps. Start to report.
Photograph
Walk the property room by room. Photograph every defect — cracks, scratches, poor finishes, incomplete work.
Log
Draw on the photo to mark exactly what's wrong. Add a description, set priority, note the room or location.
Report
Generate a numbered PDF snagging list — your logo, annotated photos, descriptions. Ready to hand to the builder.
Share
Email the PDF or share a live link. The builder works through the list. You track progress from your phone.
