Attendance that proves people were on site — replacing the paper muster roll
SitePulse is attendance and site operations for contractors and anyone with crews spread over several locations. A check-in only counts when the phone is inside the site's boundary, and the register builds itself from those check-ins.
The problem
The paper muster roll is signed at the gate and trusted only as far as the person holding the pen. It cannot be checked from the office, it has to be retyped to be totalled, and disputes about who was there come down to memory.
WhatsApp photos and selfie apps help a little, but a photo does not prove where it was taken. The job was to make presence a fact — tied to the site's boundary — and to make the register, the shifts and the follow-up happen without retyping.
Who it is for
- Contractors and builders
- Crews across several sites, paid by the day, where who was actually present is the number everything else depends on.
- Security and facility firms
- Guards and staff posted at client sites, where the client wants proof of presence.
- Site managers and supervisors
- The people who need to know about a missed check-in while it can still be fixed.

Decisions worth knowing
- The boundary decides
- A check-in is accepted or refused by the server against the site's geofence, not by the phone, so it cannot be faked by editing the app.
- Login protected at the edge
- nginx rate-limits the login and password-reset endpoints per address, on top of the application's own throttle.
- A PWA, not an app-store app
- Installs from the browser, updates without a store review, and runs on the phones site staff already have.
