Concrete Calculator Tools

• Fixed the Slab Area calculator misreading typed areas — an entry like "12 m2" could be read as a far larger number. • Results now clear the moment you change an input, so you never read a figure that no longer matches what you typed. • Unlocking Pro now applies immediately to the calculator you are already using. • Recalling a saved calculation now restores its measurement units and mode, not just the numbers. • Errors now name the field that actually caused them instead of always pointing at Depth. • Unclear entries are now rejected with a clear message instead of showing a confident 0.00. • Removed the upper limits on slab, column, post hole and stair inputs — enter any size you need. • Fixed the depth cross-section being cut off in the Slab Area diagram. • Improved the imperial keyboard toolbar on iOS 26.
