Ten tools in one
Type the sizes in: the answer comes first, big enough to read at arm’s length, then the drawing to scale. It opens where you left off.
- 01
Unit sizes
Doors, shelves, hanging rail and full height for a wardrobe or cupboard, from the outside sizes.
- 02
Door hinges
Hinge centres that miss every shelf, marked from the top or the bottom of the door.
- 03
Drawer runners
Where each pair of runners goes and the size of every drawer box and front.
- 04
Wall panelling
Picture frames on walls and up the stairs, or a batten grid: every mark, cut and mitre.
- 05
Flooring
Packs to order, the number of rows and how wide the last row comes out, room by room.
- 06
Stud wall
CLS, 2×3 or 2×4: studs, plates, noggins, the lengths to buy, plasterboard and insulation.
- 07
Spirit level
Set zero on any surface, flip check for true level, the mm to pack the low end, and a tone or a voice when your hands are full.
- 08

Both ways, to the nearest 1/8, 1/16 or 1/32, with timber lengths and door sizes ready to tap.

Questions
Is it really free?
Yes. Every tool, with no sign-up and no adverts. My kit links to the tools I use on Amazon: if you buy through one, I earn a small fee and it costs you nothing extra.
Does it work with no signal?
Yes, once it has been opened with signal. It keeps a copy of itself on the phone, so it opens in a basement, a loft or a new build with no reception.
Where are my saved jobs?
On your phone only. The app opens where you left off (Carry on, at the top of its home screen), and Save keeps a job with every number as you left it. Nothing is sent anywhere.
Why is it not in the App Store?
It is a web app: it goes on your home screen straight from the browser, opens full screen like any other app and updates by itself. No store, no download to wait for.
Who made it?
Me, Raf, a carpenter in London. These are the sums I do on every job, put where I can reach them on site.
