Check the numbers before you cut This app is a working aid, not a building authority. Timber sizes, spans, stair rules and concrete cover are set by the building code where you work, and those rules differ by country and by state. Always check a result against your local code and your own measurements before ordering material or making a cut.

Nothing happens when I press Calculate

There is no Calculate button. Results update as you type. If the results section is missing, one of the input boxes is still empty or holds something the app cannot read — a stray letter, or two dots in a number.

How do I switch between millimetres and feet?

Tap the mm or ft / in button in the top right of any calculator. It switches instantly, and it stays switched everywhere. You picked the starting one when you first opened the app.

How do I type feet and inches?

When you are in imperial, a small bar appears above the keyboard with ft, in, Space and /. Use it to build values like 8' 2 3/8". Plain decimals work too.

My results have too many decimal places

You chose this when you first opened the app. Whole numbers, one decimal place, or two. To change it, clear the app's data in Android Settings and the opening questions run again.

How do I send a result to someone?

Tap the share icon in the top right of the calculator. It stays greyed out until there is a result to send. Your phone's own share sheet opens and you pick where the text goes.

The measurements are not being read aloud

Running Measurements uses your phone's text-to-speech engine. Check the media volume is up and that a speech engine is installed under Android Settings, System, Languages and input.

Why does Concrete have two tabs?

Slab and Post holes are two different jobs, so they are two tabs on the same screen rather than a menu you have to go through. Dumpy Level and Raked Walls work the same way.

Is anything locked or paid?

No. All fourteen calculators are free. There is nothing to buy, no account and no sign-in.

Does it work with no signal?

Yes. The app has no internet permission at all. Everything runs on the phone, in a basement or out bush, with the phone in flight mode.

I think a calculation is wrong

Please tell us. Email the calculator name, every number you entered, the units you were in, and the answer you expected. That is enough to reproduce it. We take this seriously — a wrong number costs material.
