MarkSpan: Spacing Layout Tool app analytics for August 31

Enter a length and a count. MarkSpan gives you every mark position measured from the edge — so you can hook your tape once and mark them all, with no stacking error. Most spacing calculators only give you the gap size, leaving you to add it up mark by mark. MarkSpan gives you the running dimensions: 300.0, 600.0, 900.0 — exactly what you mark with a tape. LAYOUT MODES - Even gaps (ends included) — shelf pins, fence boards - Marks at both ends — fence posts, railing balusters - Even centers — screws, handles, joists - Fixed pitch — studs and joists at 455 mm / 16 in, with the leftover shown SITE TOOLS - Circle divide: chord length you can step off with a compass — not just angles - Diagonal check: target diagonal for a square frame, and which corner to push - Slope length: true length along a slope from angle, rise/run, sun-gradient or pitch BUILT FOR THE JOB SITE - Big, monospaced numbers you can read at arm's length - Tap any row to copy that one number - mm and feet-inches with real fractions (1/2, 1/4, 1/8, 1/16) - Rounding you control, with the exact error always shown - Grid layout for tile and pegboard hole patterns - Works fully offline.
