• Cleaner calculator layouts. Inputs in the Concrete, Masonry, Drywall, Paint, and Board Feet calculators are now grouped into clear, labeled sections, so it's easier to see what to enter and what the app gives back. • Know which cards to tap. Every value card now shows a pencil when it's an input you can edit and an = when it's calculated for you, with a quick tip the first time you see them. • A keypad you can feel. The number keypad now gives a light tap of feedback as you type. Turn it off anytime in Settings. • One consistent Clear key. The Clear key now works the same on every calculator: AC to start over, or C to clear just your current entry. • Better on tablets. Calculator layouts now sit centered on iPad and larger tablets instead of stretching edge to edge. • Safer stair plans. When a staircase is too tall to build as a single flight under code, CutOnce now flags it and shows how to split it into flights with an intermediate landing, instead of printing a plan you can't build. • Diagram and PDF fixes. Cleaned up overlapping labels on hip roof jack headers and on flush-mount deck stair callouts.
