Everything a tradesperson needs for one job
A room measured with the camera
Mark the corners at the floor, or under the ceiling when the room is full of things. The plan comes out with its real angles and the height at every corner, and the lean of the walls suggests the plaster layer. You can touch up the plan in your account on the site.
Tile layout plan
See where the cuts fall at the walls before you buy the tile, and how many full boxes you need.
Numbers your customer trusts
«How it’s calculated» shows each formula step by step, so nobody argues about where the figures come from.
Jobs and rooms
Every room with its sizes, windows and doors, and the work you will do in it. Floor and wall areas are counted for you.
An estimate that prices itself
Your own rates, markup on materials, discount and tax. Versions with «what changed», and cheaper or dearer options.
Works offline
