One big button to start the day and one to end it. Works with no signal, picks the right job, asks about overtime at the end — and the office gets clean timesheets, real labour cost per job and the week's pay without chasing anyone.
✓ Each worker taps Start day when they arrive and End day when they leave. The week builds itself; the office only checks.
✓ An evening reminder to anyone still clocked in, forgotten days closed overnight and flagged, and a one-tap "what time did you leave?" to fix it.
✓ Hours × each person's rate land on the job they clocked into — live labour cost against the budget, not a guess at the end.
A big button and a live timer. Starting twice from two phones is refused, so days are never counted double.
Clock-ins are kept on the phone and sent when signal comes back — basements and new builds included.
Today's scheduled job is pre-selected; workers only see the jobs they're put on.
Sent to another job or an emergency call-out — even one not in the system yet — the morning stays on the first job, the afternoon goes on the new one.
After End day the worker says how much overtime they did; you can require a reason or photo before it counts.
Location is stamped only at the moment they tap Start or End — never tracked during the day. A warning if they're far from the job, never a block.
Missed a day? Add it for the office to approve. Holiday requests from the same app.
A week grid per person and job, odd days flagged, workers confirm their own week, and paid weeks can be locked.
Paste your crew from WhatsApp or Excel, send one join link, and a readiness check shows who can clock in before Monday.
Graftum's clock-in was built and hardened for a UK contractor putting twenty people on site in one week — the double clock-ins, the forgotten evenings, the man sent to an emergency at lunchtime. It's the same app on the App Store and Google Play.
No card. Then £3–£9 a month per company, not per person until the end of your first year — and a permanent founders' discount after that. Everything on this page is included; nothing to bolt on.
Create your company →Whatever your site calls it — a clock-in app, a time card app or digital timesheets — the job is the same: who was on which site, from when to when, and what that costs. In Graftum each person taps Start day and End day on their phone; that is the time card. The office sees the week per person and per job, approves it, and it becomes the pay run.
Paper time cards get lost and are filled in on Friday from memory. WhatsApp photos have to be typed up. Generic clock-in apps don't know your jobs, CIS or day rates. Graftum is built for UK construction: jobs, day rates, overtime, CIS at 20%, 30% or gross, and no GPS tracking during the day.
Yes. Each worker's Start day and End day taps are their time card. The office gets a weekly timesheet per person and per job, ready to approve and pay.
Yes. Employed and self-employed people clock in the same way; the pay run then applies each person's CIS rate (20%, 30% or gross) or no CIS for employees.
No. It works in any phone browser, and there are also apps on the App Store and Google Play.
No. The location is recorded only at the moment someone taps Start day or End day, to show they were at the job. Nothing is tracked in between.
Start and End day still work. They're stored on the phone and sent automatically when signal comes back.
iPhone and Android (App Store and Google Play), or any phone browser. The office uses the CRM on a computer or phone.
They can fix their own days, which go to the office to approve. They can never edit anyone else's day, and paid weeks can be locked.
Sign-up and the help guides are available in seven languages; the worker app itself is in English and Romanian today.
It's part of Graftum: first 3 months completely free, no card, then £3–£9 a month per company in the founding year — per company, not per worker.
