How It Works

Three steps.
That's it.

No learning curve. Open the app, pick your calculator, enter your numbers. Setout does the rest.

Pick from 15+ trade-specific calculators. Stairs, decking, framing, roofing, concrete and more.

Enter your numbers

Type in your measurements. Use voice input to keep your hands free while you're on the tools.

Get instant results

Results appear instantly with full working shown. Save to a job for your records or hand to an apprentice.

Features

Everything you need.
Nothing you don't.

Built by tradies, for tradies. Every feature exists because someone on site needed it.

Export & Share

Send any result as a PDF or share it straight to your team. No re-typing numbers into another app.

Apprentice Mode

Every calculation shows its full working step by step. Perfect for training or double-checking your numbers.

About

Built for the tools,
not the office.

Setout was built by people who've spent time on site and know what's missing from generic calculator apps.

Our mission

To give every tradie access to fast, accurate, standards-compliant calculations — without needing a degree in engineering or a slow website.

Built in Australia

We're based in Australia and build specifically for the AU and NZ construction industry. Every calculator reflects how the trade actually works here.

Always improving

More calculators are in the pipeline. Got a calculation that's missing? We want to hear about it. Reach out at hello@setout.app
