Your app, four digitsLive
For site workers
Open the app, scan the poster. That is the whole thing.
Every system put in front of a site team fails at the same place: nobody knows what the app is, and nobody can remember the password. So the app carries your own firm’s name, and after the first sign-in it opens on four digits.
What it is like to use
Twenty seconds at the gate, and no timesheet on Friday.
The design rule for the field half is that anything requiring
a briefing has already failed. Everything below
is
either a scan, a tap or a signature.
- 01Clocking in
- Open the app, scan the QR poster, take the photograph it asks for. Confirm. The time is written by the server rather than read from the phone, so it cannot be back-dated, and the office sees the clock-in at the same instant you see the confirm screen. 5,204 clock-ins have gone through this way so far.
- 02Four digits, not a password
- You sign in once with your email address, a password and a four digit PIN. After that it is the four digits, every time. The four digits get you into the app. The scan at the poster is the construction site sign-in itself, and it is what builds the timesheet. A system that asks an operative to type a password on a wet Monday morning is a system that gets filled in by somebody else on Friday, badly.
- 03Signing for what you were told
- Toolbox talks and RAMS are signed on the screen, at the point they are delivered, by the person they were delivered to. No sheet going round on a clipboard and no signature added later by somebody who was not there.
- 04Reporting a near miss
- Twenty seconds, from the phone, with a photograph. The point of a near-miss system is volume. You want the small ones reported, and volume only happens when reporting costs almost nothing.
- 05Certificates at the appliance
- For engineers and testers, the record is made standing at the thing being tested, not typed up from a notebook that evening. The certificate generates from what was entered on site.

Six of the 25+ modules, and what each
one saves you doing.
Your firm chooses which modules you see. The app runs on a platform in daily production since 2016, shaped to the way your firm already works.

What gets asked
on the first morning.
Do I need to download an app?
Yes, and it is your employer’s own app, not a stranger’s. Search the App Store or Google Play for your firm’s name. The app carries your company name and icon, so you are installing something you recognise. It runs on any iPhone or Android made in the last decade. You sign in once, then it is a four digit PIN. The app is also the only thing that reads the poster: the code is not a web address, so a phone camera opens nothing at all. For the attendance record, that same scan is the construction site sign-in, held against you and the project rather than in a book in the cabin.
Is the company tracking where I am all day?
No. Location is checked at the moment you scan, to confirm you are inside the geofence of the site you are clocking into, set at 100 metres or less. The app records your location at the scan and at no other time, so there is no tracking between scans.
What happens to the photograph of me?
It is attached to that clock-in record as evidence of who was on site, held on UK servers in London and covered by the same retention and access rules as everything else. It is not published anywhere, and page-level access controls who in the firm can see it. See the privacy notice.
What if I forget to clock out?
The office can correct it, with a manual flag on the record so the correction is visible rather than silent. Every edit sits in an append-only audit trail with the person and the timestamp, which protects you as much as the firm, because a changed figure can always be traced back to who changed it.
Does this mean my hours get paid properly?
It means the hours reaching the office are the ones you actually worked, attributed to the right job, with a time nobody can back-date. The approved hours then export as CSV, XML or JSON straight into the payroll system your firm already uses.
The rest of the firm
Not the person who will use it most?
The same platform, described for the job each person actually does. Every one of them is a different set of pages switched on, granted per person, not a different product.
