Square every slab, peg by peg

Draw the slab, tape the diagonals, and Site Square tells you which peg to move, which way, and by how many millimetres.

Then $10 a month or $100 a year (NZD in New Zealand, USD everywhere else). Cancel any time.

How it works

Three steps from pegs to square

1

Shape

Pick a rectangle, L or T, or tap out any shape on the grid. Type the side lengths off the plan and the shape fits itself to them.

2

Measure

The app shows which sides and diagonals to tape. Key in what you read. Lines go green once they’re in tolerance.

3

Fix

Get a move for every peg — how far, and toward which corner. Hold the pegs you trust, move the rest, then re-check.
