The Problem

Hours claimed.
Presence unproven.

Current timesheets can be filled from anywhere — home, a café, a phone call. There's no reliable way to know your workers were actually on-site.

01

Paper timesheets are unverifiable

Anyone can fill in hours after the fact. No proof of physical presence on the construction site.

02

Existing tools are too complex

Accounts, logins, integrations — too much friction for workers and site managers.

03

Location is never captured

No system ties logged hours to a verified physical location at the exact moment of entry.

04

No exportable verified proof

Workers can't produce a tamper-resistant timesheet their employer can actually trust.

The Solution

How SiteProof works

Three actors, one seamless flow. No installation. No accounts. No IT department required.

01

Manager generates a QR code

Opens the app on a laptop, enters site name and project ID, captures GPS coordinates on-site. Generates a QR code and prints it. Done once — works forever.

02

Worker scans on arrival

Opens their phone camera, scans the QR on the wall. The app opens instantly in the browser — no download needed. GPS verifies they're physically on site.

03

Export a verified PDF

At the end of the week, the worker exports a clean PDF timesheet with a verification stamp. Emails it directly to their manager. No portal, no login required.

App Interface

Built for the job site, not the office

Workers see a clean, simple form the moment they scan. Site name pre-filled. GPS captured live. Done in 15 seconds.

Works in any phone browser

No app store, no installation. Scan and go.

GPS radius lock

If the worker isn't on-site, the form is blocked. Simple.

Data stays on the device

No cloud, no server, no GDPR concerns. Private by design.

⚡ Swift Mode available

Auto check-in and check-out on every scan. No manual input at all.

Features

Everything you need.
Nothing you don't.

📱

No installation required

Opens directly in the phone browser via QR scan. Workers don't need to download anything, ever.

📍

GPS radius verification

App checks GPS coordinates against the site location. Entry is blocked if the worker isn't physically there.

📄

PDF timesheet export

Weekly verified timesheet with a presence stamp. Worker emails it directly — no platform needed.

🔒

Private by design

All data stored locally on the worker's device. No server, no cloud, no GDPR complexity.

No GDPR concerns

Swift Mode

Premium check-in / check-out mode. Worker scans on arrival and departure — hours logged automatically.

Premium upgrade
🏗

Per-client branding

Each client gets their own subdomain with their company name. Professional, personalised, trusted.

Verification

Two layers of proof

Copying the URL and logging from home doesn't work. Physical presence is enforced through two independent mechanisms.

📱

QR Code Scan

Site name and GPS coordinates are encoded inside the QR. You must be physically there to scan it.

📍

GPS Radius Lock

App checks device GPS against the site coordinates. Outside the radius — entry is blocked immediately.

🕐

Time-locked Records

Entries can only be edited on the same day. After midnight — permanently locked. No backdating.

🔒

No server. No accounts. No GDPR concerns.

All data is stored locally on the worker's own device. Nothing is sent to any server. Workers own their records and choose what to share by exporting their PDF.
