What's New in CutOnce
1.9.0
July 7, 2026
• Four new calculators. Roofing Materials (shingles, bundles, squares, sheathing, underlayment, and drip edge), Concrete Blocks & Brick masonry (block and brick counts, mortar, course layout, and rebar/grout), Crown Moulding compound-miter (saw miter and bevel angles, with a nested in-position cutting mode), and Concrete Footings. • Total Cost estimating, everywhere. A new Total Cost calculator plus optional price rows you can add to Concrete Bags, Paint, Drywall, Deck, Board Feet, Masonry, Rake Wall, and Roofing — your material cost prints right on the tape and PDF. • Live diagrams on every calculator. Rafters, Arc, Deck, Rake Wall, Right Angle, and the new calculators now draw your work as you type, with cleaner, more legible labels across the board. • Sharper output. Tape and PDF strings wrap instead of clipping at the page edge, help tips scroll when they're long, and the new calculators surface any missing inputs before you cut. • New drywall sheet size. The Drywall calculator now includes the 4 x 9 ft US standard sheet, alongside 4 x 8, 4 x 10, 4 x 12, and 4 x 14. • Clearer live diagrams everywhere. Labels no longer overlap, the figure fills the full width of the card, and each calculator now shows a branded illustration before you start typing. On phones the diagrams are right-sized so nothing clips. • Roofing upgrades. Pitch now sits at the top of both Dimensions and Area modes, and on iPad you can pop the roof-plan diagram out into a larger sheet. • Reordered Toolbox. Calculators are grouped high-value-first, so the tools you reach for most are up top. • Sharper roof PDFs. Hip and Valley plans keep every angle label clear of the drawing, and the View PDF button appears only when your plan is ready to export.
