Store description excerpt
What does SlabKit do? SlabKit calculates rebar grid takeoffs, structural rebar design, wire mesh sheet counts, concrete volume, and a full set of jobsite estimators — all offline on your iPhone. Built for residential concrete contractors, framers, masons, estimators, and DIY pours. Is my data private? 100% offline. Nothing leaves your iPhone. No accounts, no analytics, no ads, no third-party tracking. How do I get started? 1. Open a tab: Slab, Mesh, or Concrete 2. Enter your dimensions in imperial or metric 3. Read the takeoff and save the project or export a PDF What can I do with it? - Lay out a rebar grid on any rectangular slab and get bar count, total linear length, weight, and number of standard-length sticks required (including lap overlap), with independent length/width spacing - Design structural rebar for columns, walls, and footings — bar size, spacing, and hook length from your load and dimensions - Estimate sheets of welded wire fabric (WWF) or rolls with adjustable overlap - Compute concrete volume for slabs, strip and pad footings, square columns, cylindrical tubes, walls, stairs, circular slabs, curbs, and post holes - Design a stairs run with code-compliance checks — riser/tread limits, stringer length, landing angle - Square up a layout with the 3-4-5 method, or plan a stepped-footing drop on sloped ground - Estimate formwork lumber, excavation volume, gravel base, block wall units and mortar, and asphalt tonnage - Count 40, 50, 60, and 80 lb (or 25 kg) bags of concrete mix, or ready-mix truckloads with short-load warnings - Design a concrete mix to US (ACI), UK/EU (BS/EN), or Indian (IS) standards - Save your local material and supplier prices in a reusable price library - Track curing with optional Day 1/3/7/28 reminders, and log test cylinders against a lab schedule - Add a waste factor and round up automatically - Save unlimited projects with custom names - Export a client quote or a formal Bill of Quantities (BOQ) as PDF for the jobsite or the supplier - Switch between imperial (#3-#8 bar, ft/in, cubic yards, lb) and metric (8-32mm bar, m/mm, cubic meters, kg) What standards does it cover? Rebar sizes follow ASTM A615 (US) and BS 4449 / EN 10080 (metric). Concrete mix design follows ACI 211, BS 8500 / EN 206, and IS 456. Stairs follow IRC tread/riser limits. All estimates are for planning — always confirm with your structural engineer or local building official. What languages does it support? English, German, French, Korean, and Japanese. How much does it cost? 3-day free trial, then $1.99/week, $4.99/month, $29.99/year, or $79.99 lifetime.
