• Pen lines snap to the ruler, even when you start slightly off the edge • Hold to complete shapes: circles, ellipses, parabolas, arrowheads, neat triangles and quadrilaterals • Math symbols palette, with a square root that stretches over the expression • Ask AI: select any area and send it as a picture to the AI app you choose • Write with the pen on a picture right after tapping it, plus an Edit button for pictures • Recording: pause and resume in one recording • Fixes and improvements

Inksound 1.2 brings the tools engineering students asked for: • Pages flow as one continuous sheet, with smooth momentum scrolling. Writing that crosses a page break stays whole. • Engineering paper at true scale: 5 mm grid, millimeter paper, engineering pad and isometric paper, in A4, Letter, A5 and A3. • Shapes: hold the pencil at the end of a line, arrow, box, circle or curve and it snaps into an editable shape with handles and fills. • Ready-made engineering items: axes, asymptotes, triangles, unit circle, free body diagram, beams, springs and circuit symbols. • A ruler you can move and rotate, with measurements in cm. • Favorites: up to 16 saved pens with widths in mm, dashed and dotted lines, and an eyedropper. • Lasso tools: copy and paste between notes, rotate, mirror, group and save items for reuse. • Image editing: crop, rotate, fix perspective and scan filters, always reversible. • One Import button for PDFs, pictures and Notability notes. Whole Notability libraries keep their folders, shapes and grid spacing. • Many fixes and performance improvements.
