Slab turns the numbers on your tape measure into exactly how much material to order — and what it costs — fully offline, right on the jobsite. Pick what you're pouring, enter your dimensions in feet-and-inches (12' 6 1/2") or metric, set your waste %, and get a big, legible answer you can trust: cubic yards or cubic meters, bag counts for 40, 50, 60 and 80-lb bags, ready-mix trucks, rebar bar count and tonnage, block and mortar, gravel tons. Bag counts always round up to full bags, so you never come up short. WHY CREWS PAY ONCE FOR SLAB • A real dollar quote. Add your unit cost per bag, per yard, per ton or per foot of rebar and Slab gives you a line total and a project total — an estimate you can hand a client or text to the supplier. • Saved projects. Keep a whole job in one place — slab + footing + gravel base + rebar — with running material and cost totals across every area. • Every material a crew pours. Slab, footing, wall, columns (rectangular and round/Sonotube-style), stairs, rebar, CMU block + mortar, gravel and soil. • Feet-inches the way you read a tape — and clean metric for the rest of the world. • Results that never get cut off. Big tabular numbers that scale with your text size and never truncate. • Share a clean quote. Export a tidy PDF or text summary through the share sheet — generated offline. PAID ONCE. OWNED FOREVER. No subscription, ever. No ads. No account, no sign-up. Your projects stay on your device — data not collected. Works fully offline, in airplane mode, in a basement with no signal. EVERYTHING INCLUDED One price up front, every feature included: every material, dollar cost quotes, saved projects, and PDF/text export. No in-app purchases. Built for concrete, masonry and hardscape crews, owner-operators, foremen, and DIY-pros doing a pour.
