What's a Snag List, and Why Does It Always Go Sideways?
A snag list — or punch list, depending on which side of the Atlantic you're on — is the running record of everything that's wrong on a site before handover. Wrong tile. Missed trim. Hairline crack near a window. A door that doesn't latch.
The list itself is the easy part. The hard part is making it stick. A typical site snag list gets scribbled in a notebook, then copy-pasted into WhatsApp, then photographed and forwarded, then someone says "which wall?" and you're scrolling back through three weeks of chat to find a photo you can't remember sending. Stuff falls through the cracks. Handover slips. The client notices.
Kronos is built for one specific job: give every snag a permanent home on the photo where you found it. You upload the photo, pin the issue, write what's wrong, and share a single link with the contractor. They see the same pins you do. They mark them done. Everyone's looking at the same picture.
How a Snag List Works in Kronos
Upload the photo
From your phone or laptop. Snap on-site or pull from your gallery. Floor plans (PDF) and 3D models work too.
Pin every issue
Tap the spot on the photo. Add a title, a note, a severity if you want. Each pin is a separate snag with its own status.
Share the link
Send one URL to your contractor via WhatsApp, SMS, or email. They open it in any browser. No account, no app install.
Why Site Teams Use Kronos for Snagging
Pins on the actual photo
Not a row in a spreadsheet. Your contractor sees exactly which doorknob, which tile, which pipe. No more 'which wall?'
Share without accounts
One public link, opens in any browser. Contractors, subcontractors, owner reps — nobody needs to sign up to participate.
Status per snag
Open, in progress, done, rejected. Track each issue to closure without spinning up a whole project-management system.
Floor plans and 3D models too
Pin issues on a PDF floor plan, a point cloud scan, or a GLB 3D model. Same workflow, more visual context.
Works from any phone
Mobile-first. Drop pins on the spot. No app install — it's a website.
Free, no card, no upsell
10 projects, 5 GB storage, unlimited shares. Free forever. If you outgrow it, tell us — we'll figure something out.
Frequently Asked Questions
What is a snag list?
expand_more
A snag list (sometimes called a punch list in the US) is a written record of defects, unfinished work, or issues spotted during a site walk-through. Traditionally written on paper or in a notebook, then chased down via phone, WhatsApp, or email. Kronos turns this into a visual pin on the actual photo of the problem, sharable with one link.
How is this different from a punch list app?
expand_more
"Snag list" and "punch list" describe the same workflow — UK and Irish trades say snag list, US trades say punch list. Kronos works for both. The difference from most punch list apps is that pins live on photos and 3D models, not on a flat list of text rows, so your contractor sees exactly which doorknob, tile, or pipe you mean.
Do I need an account to start?
expand_more
No. Upload a photo and start pinning in seconds — no signup, no card, no email. Sign up later if you want to keep the project and access it from another device.
Can I share a snag list with my contractor without making them sign up?
expand_more
Yes. Every project gets a public share link. Send it via WhatsApp, SMS, or email — your contractor opens it in their browser, sees the pinned issues, and marks them done. No account required on their end.
Is it really free?
expand_more
Yes — Kronos is free to use. The free plan includes 10 projects, 5 GB of storage, and unlimited shares with no expiry. No credit card, no upsell.
What files can I upload?
expand_more
Photos (JPG, PNG, HEIC), floor plans (PDF, image), and 3D models (GLB, OBJ, point clouds). Pins are placed in 2D for photos and floor plans, in true 3D space for models.
Does it work on mobile?
expand_more
Yes — Kronos runs in any modern mobile browser. Snap a photo on site, drop pins on the spot, share the link before you leave. No app install required.
