Coming to the App Store, for iPhone

SiteCalc

Every material, one app, priced out.

SiteCalc works out how much concrete, block, brick, stone or soil a job needs, in yards, bags and tons, and with Pro it tells you what that'll cost at your own supplier's prices. It does the work of a shelf of single-purpose calculators in one place, and it shows the formula behind every answer so you can check it yourself.

SiteCalc's home screen, headed 'Every material. One app. Priced out.', with a feet-and-inches or metric switch and cards for concrete, fast-setting concrete, concrete block, brick, gravel and crushed stone, and sand.

Every calculator is free

An estimate you need standing on a job site shouldn't sit behind a paywall, so every calculator is free, with no ads:

Pro

Pro is for turning the numbers into a job and the job into a price.

Where the numbers come from

Bag yields, block counts and weights come from manufacturers' data sheets and from standards bodies, and every one is cited in the app. Where nobody publishes a single trustworthy figure, as with loose gravel, whose weight changes with the quarry, the size and how wet it is, SiteCalc asks for the number your supplier quotes instead of guessing.

Pricing

These are the prices we plan to launch Pro at, in US dollars; the App Store shows the final price in your own currency before you buy, and that's the one that counts.

SiteCalc Pro, planned launch prices
PlanPrice
Yearly, with a 7-day free trial$44.99 a year
Monthly$6.99 a month
Lifetime, paid once$99.99

SiteCalc brings up Pro only when you tap a Pro feature, and it never interrupts a calculation to sell you something.

Your data

There's no account, no ads and no tracking. Your jobs, prices, customer details and logo are stored on your iPhone and never sent to us, and estimates and exports go only where you send them. The privacy policy has the details.

A note on accuracy

Every result is an estimate built from the dimensions you enter and the published figures behind each material. Real sites vary, so allow for your ground and your forms, follow the manufacturer's directions, and check quantities with your supplier before you order.
