How it works

From first launch to first submission.

01

Receive invite link

Your admin sends a unique invite link by text or email. Click it and install the app on iOS or Android. No app store account needed.

02

Set a PIN

On first launch, create a 4 or 6 digit PIN to access the app. That's it — no username or password. Optional: unlock with your fingerprint.

03

Select a project

See only the projects you've been invited to. Each project is separate — you'll only see work related to you.

04

Take a photo

Choose what you're capturing (Waste Ticket, Delivery Note, Receipt, or Other). Photograph the document with your phone camera or upload from your gallery.

05

Review the data

The app automatically reads the key numbers from your photo — weight, dates, supplier name. Check it's right and edit if needed.

06

Send it in (works offline)

Tap submit. The data is saved on your phone first. When you connect to WiFi or mobile data, it syncs automatically to your team.

Data extraction

What the app reads.

The app automatically identifies and extracts structured fields from photos of your documents. If the app is unsure about a value, it flags it for you to confirm manually.

Waste ticket

Weight, waste type, date, vehicle number, location

Delivery note

What was delivered, how much, where it went, who sent it, when it arrived

Fuel receipt

Fuel type, amount, vehicle number, date, cost

Other documents

Upload any document — the app will extract the text for you to categorize

Field worker data isolation.

A field_worker role has zero access to org dashboards, calculations, or other users' submissions. They see only the reporting periods they were invited to and the status of their own submissions. Access is enforced server-side on every API request, not from client-supplied headers.
