Construction Calculator: Rebar
Concrete Slab & Cost Estimator
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
19 construction calculators in one app. Concrete, rebar, gravel, tile and more — offline, metric or imperial, with PDF estimates.
The third trip to the builder's yard is never in the quote. SiteCalc turns the numbers you're juggling on site — slab, rebar, gravel, blocks — into exact quantities and bags in seconds, so you order once and pour once.
You know the routine: pacing out a slab with your phone calculator in one hand, converting inches in your head, scribbling bag counts on an offcut. Then the ready-mix truck arrives half a yard short. SiteCalc takes that weight off your shoulders.
EVERY SITE CALC IN ONE APP
• Concrete: slab, footing, column, form tubes, stairs, wall, post holes
• Rebar grids: bar counts, total length and steel weight
• Gravel, sand, asphalt and excavation with swell factors and truckloads
• Blocks and bricks with mortar bags, screed, drywall with screws and tape
• Paint, tile with adhesive and grout, pavers, soil and mulch, fence
METRIC OR IMPERIAL, INSTANTLY
• Flip the whole app — or a single field
• Mix meters and inches on the same job
• Regional bag, bar and block sizes built in
COST THE JOB. SEND THE PDF.
• Save any result into a job
• Add your unit prices — the total builds live
• Export a clean PDF estimate or CSV before you leave the site
BUILT FOR REAL LIFE
• Contractors quoting a garage slab off the tailgate
• Landscapers ordering gravel and pavers by the tonne
• Renovators tiling a bathroom over a weekend
• Fencers counting posts, rails and bags of post mix
• Anyone tired of ordering 10% short — or 30% over
PRIVATE BY DEFAULT
No account. No ads. No tracking. Everything runs on your phone and keeps working in a basement, behind a barn, or three floors underground.
