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.

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:
- concrete for slabs, footings, walls, columns, steps and curbs, and fast-setting mix for fence and deck posts;
- concrete block and brick, with the mortar and grout that go with them;
- gravel and crushed stone, asphalt, topsoil, mulch, sand, pavers and rebar;
- results in cubic yards, bags and tons, with a waste factor;
- feet and inches, or metric;
- the formula behind every result, one tap away.
Pro
Pro is for turning the numbers into a job and the job into a price.
- Material pricing. Your own prices per yard, bag, ton or piece, plus delivery, so every result shows its cost.
- Saved jobs. Every pour and every material for a job kept together, with running totals.
- A customer estimate PDF with your logo, line items, labor and markup, ready to send from the driveway.
- CSV export and backup, so the takeoff can go into your spreadsheet and your jobs and price lists can come with you to a new phone.
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.
| Plan | Price |
|---|---|
| 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.
