That is what separates a snagging app from a camera and a notebook. Punch List & Site Audit logs every snag with a marked-up photo, its location and the trade responsible, then builds a PDF for one subcontractor at a time that you can send from your phone before you leave site, with or without signal.
For most UK site teams, the best snagging app is the one that turns a walkround into lists subcontractors can act on the same day: a marked-up photo on every snag, the location and trade against it, and a PDF that leaves site with you. Punch List & Site Audit does that on iPhone, iPad and Android, works without signal and is free to use, with watermarked PDFs until you upgrade to Pro.
Learn more: what belongs on a snag list.
Snagging is the walkround that turns “nearly finished” into a list of named defects, each with an owner and a date. On most UK jobs it happens at three points, and each time the list has to reach someone different.
The site manager or main contractor walks each plot, floor or unit and logs everything still to do: missing sealant, chipped skirting, a door that catches, a socket without its faceplate. Snags still open at practical completion are often handed over as an agreed schedule of defects, so they need to be numbered, located and photographed clearly enough for someone else to close them.
After handover the client reports defects throughout the defects liability period (the Rectification Period in JCT contracts), commonly six or twelve months. Each one has to be traced to the trade that did the work, sent to them, re-inspected and closed, often long after that subcontractor has left site.
Buyers and professional snagging inspectors list defects room by room, ideally before completion or soon after moving in, and send them to the developer. A snag list where every photo has the problem circled is far easier for a customer care team to act on than an email of loose pictures, and it is best sent early, while defects fall within the builder's own two-year warranty period.
Six steps from the first snag to a PDF in the subcontractor's inbox, all on the phone you already carry.
Create a project for the site, plot or flat with the client's name and the address. Each project keeps its own snags, a count of what is still open and how far through you are.
Give each snag a short title, a description and a location (room, floor or zone), then tap Save & Add Another and move straight on to the next one.
Take a photo or pick one from your library, then add an arrow, circle, box, numbered marker, text or a freehand line in the colour and thickness you want, so nobody fixes the wrong socket.
Type the subcontractor or trade into Assigned To (names you have used before are suggested), add a category such as Electrical, Plumbing or Painting, and set a priority and a due date.
On the report screen, pick that assignee and keep only Open and In Progress, so the electrician sees just the electrician's outstanding snags. Compact gives one line per snag; Detailed gives a page per snag with full-size photos.
Share the PDF from your phone by email, WhatsApp or Messages. Choose Small photo quality if it has to fit an email attachment; the file size is shown before you send. The subcontractor just opens a PDF, with no app or login.
Most snagging apps can take a photo and keep a list. The differences show when the list has to leave site and get acted on. Whichever apps you are comparing, check these points:
Screenshots from the iPhone app, with the details that matter when the snag list is going out to subcontractors.
Title, description, location and photos sit in one form, and Save & Add Another keeps the walkround moving.
Annotate the photo before it goes into the report, so the subcontractor sees the defect, not just the room.
Status, priority, category, assignee and due date turn each snag into a job that belongs to someone.
Snag numbers, status, priority, due dates, assignees and photos, generated on the phone rather than typed up later.
Search and filter snags by status, priority, category and assignee, in the app and on the report.
Each project has its own snags, open-snag count and progress, and search finds it by name, client or location.
Main contractors and site managers running handovers, fit-out and refurbishment firms, snagging inspectors and homebuyers: anyone whose job is to find snags, get them to the right trade and see them closed, without training a whole supply chain on new software.
If snags have to be pinned to drawings, tied to RFIs and document control, or worked on by several companies logging in to one system, a full construction management platform is the better fit. On its own, each person's snag lists live on their own devices and subcontractors receive a PDF rather than an account; PunchList Business adds shared team projects for crews who need to work on the same lists.
Choose an app that can filter the snag list by trade and export a PDF with the photos inside it, so each subcontractor gets only their own snags. In Punch List & Site Audit you assign each snag, filter the report by that assignee and share the PDF from your phone by email, WhatsApp or Messages. The subcontractor needs no app and no login.
Yes. Punch List & Site Audit is free to download on iPhone, iPad and Android, with unlimited projects, snags and photos. PDF reports on the free version carry a watermark; Pro removes it, adds your company logo and contact details, and unlocks project import and export.
Yes. Projects, snags and photos are stored on the device and the PDF is generated there too, so you can snag a basement, a riser or a plot with no Wi-Fi and send the report as soon as you have coverage.
Yes. Walk the property room by room, log each defect with a marked-up photo and send the developer a PDF snag list. Every report is dated and each snag shows when it was added, which helps when you chase items that are still open.
Yes. The app is on Google Play for Android phones and on the App Store for iPhone and iPad, where in the UK it is listed as Snag List & Site Audit Pro. Snags, mark-up, filters and PDF reports work the same way on both.
Free to download on iPhone, iPad and Android. Log your next walkround in the app and send each subcontractor their snags before you leave site.
