01 / The record Every capture. Every detail. Accounted for.
Evidence, not memory

Photos disappear.
The record doesn't.

Every photo, clip and note is stamped with who, where and when, filed against the job, and there in the office before the engineer is back in the van.

How it works

From site visit
to signed-off job.

One flow for every install. Film it, photograph it, mark it up, hand the office a report. No WhatsApp threads, no camera roll archaeology.

01

Survey

Film a walkthrough, scan the room, tap in the customer. The AI drafts the survey and the engineer's brief from the footage.

02

Capture

Photos, clips and voice notes straight to the job. Arrival and departure logged automatically from the site geofence.

03

Mark up

Arrows, circles, measurements and pipe routes on any photo or plan. Calibrate a plan once and every run is in metres.

04

Report

Commissioning sheets, F-Gas records, photo reports and customer updates, signed on the phone and sent as PDF.

Built for engineers

Everything the job needs,
in the engineer's pocket.

Built on real installs, not in a boardroom. Big buttons, few taps, works with gloves on and no signal.

Office + field

One job. One record.
Phone and office, live.

Engineers work from the phone. The office works from the browser. Same jobs, same photos, same chat, updated the second anything happens.

Shoot from inside the job. Unlimited walkthrough recording, captions by voice, tags and before/after pairs.

› stamped · queued offline · synced
Markups & plans

Draw on it. Measure it.

Pen, arrows, boxes, text, measure and pipe-route tools on photos and PDF plans. LiDAR room scans become to-scale plans.

› pipe run 7.4 m · trunking 3.2 m
Site log

Arrive. Leave. Logged.

Geofenced sites stamp arrival and departure automatically. Missed bookings get flagged the next morning.

› 08:12 arrived · 16:40 left · confirmed
Chat & customer updates

Job chat. Customer texts.

A chat per job with @mentions on photos. Customers get "we're on our way" and day-before reminders by SMS and email.

› reminder 17:00 · on-our-way · done
Plays nicely

Works with the tools you already pay for.

Invoices and receipts scanned into the job costs, customers looked up from Xero, PDFs shared anywhere.

Built for HVAC

Made for splits, VRF
and the paperwork that follows.

Generic job apps stop at photos. WorkProof knows what an F-Gas record is, what a commissioning sheet needs, and which unit is due a service.

Unit register with QR stickersEvery indoor and outdoor unit on record: make, model, serial, refrigerant, install date. Scan the sticker on site and the history opens.
F-Gas logCharge, recovery and leak-check events against the unit, with the engineer's cert number, ready for an audit.
Commissioning sheetsPressures, temperatures, vacuum, electrical readings and the customer's signature on the phone. PDF to the customer in one tap.
Breakdown & service visitsFault, cause, fix, parts. Service due dates roll forward on their own and remind the office.
Install kits & materialsAdd a standard single-split kit to the job in one tap, tick off what was used, scan the receipts into costs.
AI survey briefThe engineer's brief comes out of the walkthrough video: units, wall types, estimated pipe runs and difficulty, in bullet points.
For the office

The office sees it
as it happens.

Dashboard, dispatch board and jobs table in any browser. Drag a job to another day or engineer, and their phone updates.

Why it exists
I got tired of scrolling through 4,000 photos on a Sunday night to prove we'd done the job.

— The founder, an air-conditioning installer who still goes out on installs

WorkProof started as a tool for one installation company that had outgrown WhatsApp groups and camera rolls. Every feature was built on a real job, tested by real engineers, and thrown out if it needed more than a couple of taps. It runs a working HVAC business every day. Now it's opening up to yours.

Questions

Straight answers.

Does it work with no signal?

Yes. Photos, clips and notes queue on the phone and upload when you're back in range. Nothing is lost if the app closes or the phone restarts.

Which phones does it run on?

iPhone (iOS 16 or later) and Android 10 or later. LiDAR room scans need an iPhone Pro; other phones measure rooms by tapping corners on the floor.

Do the office staff need the app?

No. The office works from any browser at app.workproof.site with the same login. Phones for the field, browser for the desk.

Is our data ours?

Yes. Your jobs, photos and records belong to your company. Export PDFs at any time, and ask for a full export if you ever leave.

What happens to the price after early access?

Early-access companies keep the prices shown for 12 months from the day billing starts. You get a month's notice before that.

Can you import our existing jobs?

Company plans include an import from a spreadsheet or your current job system. Smaller teams can add jobs in a few taps each.
