Why I built this
I was the engineer with 2,000 unorganised site photos
I'm Kyle — a structural engineering technician manager in the UK. Every week I'd come back from site inspections with hundreds of photos buried in folders labelled things like “Site Visit 14 — Feb.”
Matching photos to locations meant cross-referencing drawings, scribbled notes, and hoping someone remembered which beam was which. Half the time we'd end up going back to site because a photo was missing context.
Matterport, OpenSpace, and the big scanning platforms wanted £10k+ per projectand specialist hardware. That's fine for big developers — but most engineering firms don't have that budget.
So I built pin360: upload the PDF floor plan you already have, pin 360° photos from a consumer camera, share a link. That's it. No scanning rigs. No training. Five minutes from site photos to shared report.

Founder-led by the target user
pin360 is built by a working UK structural engineering technician manager who deals with site photos, drawings, markups, and client records in the real world — not by a generic construction SaaS team guessing from the outside.
Evidence command centre
No more photo archaeology.
pin360 turns a loose folder of site photos into construction photo management software: every photo, 360° view, note, and defect is pinned to a PDF floor plan location.
LOC-01
No more mystery photos
Stop asking ‘which wall was this?’ two weeks after the visit. Each image sits on the exact plan marker it belongs to.
CHK-02
Catch missed angles earlier
Review the 360° view, close-up photos, and finding notes before the next maintenance decision depends on them.
REV-03
No more detached comments
Questions stay beside the marker, not buried in email. Reply with evidence, then close the thread with the record intact.
SHR-04
No more loose-file handovers
Send one link with the plan, pins, photos, findings, and review context so stakeholders can follow the site record.

A site record people can follow.
Turn PDF drawings and field photos into a location-aware evidence chain without changing how your team captures site information.
1
Plan
Start with the PDF drawing, site map, or building layout your team already uses. No new drawing format required.

Pin
Drop 360° panorama, standard photo, and finding pins at the exact place the evidence belongs on the plan.

Review
Clients, consultants, and facilities teams discuss the marker itself instead of chasing context through email threads.

Resolve
Reply with supporting evidence, mark the discussion resolved, and keep the decision trail beside the finding.

Send a read-only link stakeholders can follow without reconstructing the site visit from loose files.
See it in action
Watch the plan-to-pin workflow
See how a floor-plan marker opens the 360° context, finding notes, and close-up evidence for the exact place under review.
- 1
Start from the plan
Open the PDF drawing, choose the location marker, and jump straight into the evidence captured there.
- 2
Pin detail inside the 360° view
Drop findings in the panorama, add severity, and keep close-up photos tied to the same plan location.
- 3
Review the exact evidence
Use thumbnails and marker context to move from the plan to the defect without hunting through folders.
Evidence kit
The inspection loop now runs from evidence to review.
pin360 is no longer just a place to store 360° photos. It is site inspection photo software for PDF drawings, standard photos, panoramas, finding pins, client questions, and resolved review threads.

How pin360 compares to the alternatives
Enterprise scanning platforms charge tens of thousands. Spreadsheets are free but painful. pin360 is the middle ground that actually works.

Frequently asked questions
Everything you need to know before getting started.
No. pin360 works with normal phone photos too — just pin them to your floor plan like any other image. 360° cameras (Insta360, Ricoh Theta, GoPro Max) give you the full-room view, but a phone photo of a crack or a defect works just as well. Most teams use both.
PDF annotations are static — you can circle a spot and attach a photo reference, but you can't step inside the space. pin360 lets you click a pin on the floor plan and open the actual photo (or 360° panorama) taken from that exact location. And when you share a link, your client or team can navigate the whole site without any software installed.
pin360 isn't a replacement for point cloud scanning — it's for the 90% of site visits that don't justify specialist hardware. Most firms use both: Matterport for landmark projects, pin360 for everyday condition surveys and inspections.
Static PDF annotations can't embed a 360° viewer. And they break when photos are updated. pin360 keeps your panoramas live and navigable — click a pin, step inside the space.
If they can use Google Maps, they can use pin360. Upload a drawing, drop a pin, attach a photo. Most teams are documenting their first project within 5 minutes.
