The snagging app that puts every snag on the plan
Photograph the defect, pin it where it is on the floor plan, add a note and a trade, and hand over a PDF snag report before you leave site. For site managers, clerks of works, contractors and new-build homebuyers.

Walk the building once. The snag list builds itself.
No clipboard, no sorting 200 photos called IMG_4471 at your desk that evening.
Photograph the snag
Open the camera inside the project. Choose "Issue", dictate or type the note, and GPS and time are attached automatically.

Pin it to the plan
Tap where it is on the floor plan. Issues show as red pins, so the open snags on each floor are visible at a glance.

Send the snag report
One tap builds the PDF: a cover sheet, a summary, and a page per snag with its photo, note and plan extract.

Built for the snagging walk, not the office
One hand free, gloves on, bright sun, no signal and 20% battery. SIAPP is designed around that walk, and around the person who has to read the report afterwards.
