Construction Calculator Suite

Measure once, price it twice.

Most construction calculators hand you a number and stop there. This one keeps going: every calculation ends in a material list with your own prices on it, and a total you can show a client or take straight to the counter.

Five calculators, one app:

• Concrete calculator - slab, footing or column. Cubic yards or cubic metres, plus the exact bag count for 60 lb and 80 lb mixes.
• Paint calculator - walls and ceiling minus doors and windows, coats and coverage, rounded up to whole cans.
• Stair calculator - total rise in; riser count, riser height, treads and stringer length out, with a warning when a riser or tread falls outside code.
• Drywall calculator - sheets for 4 x 8 or 4 x 12, plus screws, joint compound and tape.
• Fence calculator - posts, rails, pickets and bags of mix from length, post spacing and picket width.

Then the part most calculators skip:

• A priced estimate, not just a quantity: material, quantity, unit, unit price, line total, grand total.
• Your prices. Edit any unit price right in the estimate and it is remembered for every job after that. Your own price list, your own currency.
• Saved jobs. Name an estimate and it comes back whole - dimensions and material list together.
• Visual input. A drawing of what you are measuring highlights the dimension you are typing, so you always know which number goes where.
• Imperial or metric, switched everywhere at once.
• A waste allowance on every calculation.

Built for contractors pricing a job on site, foremen checking a delivery, and homeowners who would rather buy the right amount the first time.

Works with no signal. All five calculators, the estimate, the price list and your saved jobs run fully offline from the first launch. No account, no sign-in, nothing to sync - your prices and your jobs stay on the device.

Free. The five calculators, priced estimates, your own price list and three saved jobs cost nothing; ads pay for the app. One short clip unlocks estimate export and extra saved jobs for a day.

Measure it, price it, buy it once.
