SlabMate: Concrete Calculator

Custom bag sizes, prices and mix ratios are now free, so every estimate can use your merchant's real yields and rates. Premium remains saved jobs. Imperial measurements also read back the way you type them. Switch to feet and inches and the result, the inputs list and the estimate you share all use them, so there is no metric conversion to double-check. Also in this release: - Every bag size, price and mix ratio is editable and removable, including the ones SlabMate ships with - Small pours keep their figures instead of rounding away, and the notes restate the volume in millilitres - A premix result names what you buy, so the bag count and purchased weight are never read as the concrete required - Switching measurement system no longer leaves a converted value like "149.9997" sitting in a field - Unlocking premium now finishes the save or duplicate you asked for, instead of returning you empty-handed - The site mix ratio appears only when you are mixing on site - Saved jobs state their volume once, in the unit you chose - Site mix lists cement alongside sand, aggregate or ballast, and prices bulk bags when they work out cheaper - Ready-mix quotes your supplier's minimum load rather than a part load - Clearer warnings for shallow footings, oversized post holes, and pours that need one continuous go - Optional anonymous usage and issue reporting, switched off by default and controlled in Settings
