The full calculator
Choose your trade, punch in the measurements, and Pro does the rest — quantities with waste built in, a shopping list priced at real UK trade rates adjusted for your region, and the method written out step by step so you know the order of work before you start.
Quantities, not guesses
Bags, boards, litres and linear metres worked out from your dimensions, with typical waste allowances included.
A costed shopping list
Every material priced so you can budget the whole job, with a running total — copy or share it straight to your phone.
The method, in order
Step-by-step instructions for the job itself — prep, laying, finishing — so nothing catches you out halfway through.

Photo site check
Before you buy anything, photograph the work area and let Pro look at it. It reads what it can see — cracks, damp patches, uneven floors, loose plaster, drainage and more — and lists the preparation steps for your specific job, so problems surface on day zero instead of day three.
What it can see
Visible site considerations in your photo, each with a note on how likely it is to matter for the trade you've picked.
What to do about it
An ordered prep list for your project — what to sort first, what it might add to the job, and when to call a professional instead.
The photo check reads only the photo you upload, one job at a time — nothing is used to train anything.
Projects, saved and tracked
Every calculation can become a saved project. Come back days later — the inputs are kept, so the shopping list and method are exactly as you left them — and tick steps off as the job progresses from your dashboard.
Everything in one place
Trade, measurements, list, cost and progress on a single card per project.
Progress you can see
Tick off instructions as you go and watch the project move towards done.
PDF, ready for the merchant
Export quantities, the costed list and the method as a PDF — print it or keep it on your phone at the trade counter.
