T2QCAL
the calculator
that quotes.
Ninety-two construction calculators for iPhone, each drawing the job as you type it. It signs in with your Tradies2Quote account, so a quantity worked out standing in the trench goes onto your quote list before you've got back to the ute.
The manuals you'd otherwise be googling — GIB, MiTek, James Hardie, Pryda, Concrete NZ — sit on the phone and read with no signal.
Tell me when it lands
Same login.
Same rates.
There is no second sign-up. T2QCAL authenticates against the same server Tradies2Quote does, so your email and password work in both — and your labour rate, markup, GST rate and currency are read from the same profile the website prices from. Change your markup in settings and the calculator quotes at the new one next time you open it. The two cannot drift apart, because there is only one copy.
Sign in once
Your Tradies2Quote email and password. No separate account, no extra subscription.
Your own numbers
Markup, GST rate, tax label and currency come off your profile — not a default someone else picked.
Signed out still works
Every calculator and the whole manual shelf run without an account. Signing in is only for sending a quote.
Measured.
Not guessed.
Work out the slab, tap Send to a quote, and the quantities go across as a draft on your quote list — described, measured and priced at your markup and your GST. Open it in Tradies2Quote to add labour, pick the client and send it.
Nothing goes across unseen
Every quantity is listed with a tick and every figure stays editable. You approve the list, not a black box.
It won't count the same concrete twice
On a slab, “order volume” is ticked and the “net volume” beside it isn't — they're the same pour, once with waste and once without. Cut lengths start unticked too: a rafter length is something you cut to, not something you order.
It won't re-ask what you just measured
The lines are marked as calculated, which is the flag Tradies2Quote uses to tell a measured quantity from an AI-guessed one. It doesn't make you confirm them again.
92 calculators.
Every one draws.
Not a list of formulas — each tool draws the thing you're building as you type: a measured sheet with the dimensions on it, a set-out detail, and a 3D assembly of the actual job. A rafter calculator draws the birdsmouth. A stair calculator draws the stringer.

72 manuals.
No signal needed.
Span tables, fixing schedules, bracing ratings, wet-area details — pulled down once over wifi and readable in a subfloor, a stairwell or a valley with no reception. Searchable, with the page count and match counter right there. The Building Code clauses are on the shelf too, linked rather than stored, because MBIE will not serve the files to an app.

62 download directly
The other 10 sit behind a bot check or a free registration, so the app opens the publisher's page rather than quietly saving an error page.
Always the current issue
Nothing is bundled into the app. Pull a manual again and you get whatever the publisher is issuing today.
The number,
and the clause behind it.
74 of the 92 calculators carry a link to the rule that governs them, and it opens the manual at the right search term — not the front cover, and not a search box on a website.
Set out joists and the GIB Site Guide opens at “fixing centres”; pour a slab and the CCANZ guide opens at “slab”. Work out a flight of stairs and MiTek's stair tread bracket sheet opens at “tread”, with D1 Access routes and F4 Safety from falling listed beside it — those two go to MBIE's own page, because the Building Code site blocks downloads and the app says so rather than saving you an error page.
The eighteen calculators that carry nothing are the ten converters and the eight printable templates. No clause governs a millimetres-to-inches conversion, and padding it with a plausible-looking reference would be worse than saying nothing.
Every one of those references is checked automatically against the library, so a link can't rot into a dead end.
Built and working.
Not on the App Store yet.
T2QCAL runs on real phones today, but it's in beta and there's no public download link to give you — putting one on the App Store is the next step. Leave your email and you'll get one message when it's installable. Not a newsletter.
- What does it cost?
- Nothing on top of Tradies2Quote. It's part of the same account, not a second subscription.
- Do I need an account to use the calculators?
- No. Every calculator and the whole manual shelf work signed out. The account is only what ties a quantity to your quote list.
- Android?
- Not yet — it's a native iPhone app. Tradies2Quote itself runs on Android through the browser.
- Does it store the manuals?
- It fetches each one from the publisher's own address onto your phone and keeps it for offline reading. They stay the publisher's files, and pulling one again gets whatever they're currently issuing — which for a span table is the difference that matters.
