ScaleTap: PDF Plan Measure

Fast Construction Takeoff

Free · In‑App Purchases

iPad

Measure PDF plans on iPad with reliable scale calibration, six takeoff tools, and live handle editing. Export XLSX, CSV, or annotated PDFs—fully offline. ScaleTap is the fastest way to measure construction plans on iPad. Import a PDF, set the scale, and pull takeoff quantities with Apple Pencil — on the jobsite, fully offline. Placing a measurement takes seconds. Now fixing one does too: drag a handle on any measurement and the value updates live as you move it. No tool switching, no fighting the app. MEASURE EVERYTHING ON THE PLAN • Lengths, areas with perimeter, multi-segment runs, counts, angles and arcs, and volumes • Dynamic Fill: switch Area to Fill and tap inside a room to trace its boundary into an area measurement — on scanned plans too • Find Similar: frame one symbol and ScaleTap finds matching instances on the page or across all pages, reviewed before they're added to your count • Deduct windows, doors, and voids from area measurements for accurate net-area takeoffs • Values appear live as you draw and as you edit • Snap to the drawing itself — endpoints, midpoints, intersections, centers — plus grid snap and orthogonal/45°/15° angle constraints • Numbered count marks grouped into named categories for fast tallying A SCALE YOU CAN TRUST A wrong scale means wrong numbers, so ScaleTap treats scale as a first-class tool: • Calibrate from a known dimension, pick a preset architectural/engineering/metric scale, or trace the printed scale bar • A verify prompt helps you sanity-check a new scale against a known dimension • Different scales on different pages — and scale regions for multi-scale sheets (plan at 1/8" and detail at 1/2" on the same page) EXPORTS YOUR OFFICE CAN USE • CSV and native Excel (XLSX) with groups, subtotals, grand totals, and scale provenance — ready for estimating • Flattened, annotated PDFs that open cleanly in the PDF tools your office already uses • Optional measurement summary report appended to the PDF • XFDF import/export for exchanging annotations with desktop PDF tools • Export the whole document, the current page, only pages with measurements, or a custom range like 1-3, 5, 9 BUILT FOR THE FIELD • Fully offline: no account, no cloud, no signal required • Autosave protects your work — even through a force quit • Pencil draws, finger pans; two-finger undo and three-finger redo work the way you expect • Hardware keyboard shortcuts for Magic Keyboard users • English, German, French, and Japanese, with VoiceOver and Dynamic Type support FREE AND PRO Viewing PDFs, markup (ink, highlights, arrows, shapes, text callouts), and XFDF annotation exchange are free. Measurement tools, calibration, and data/PDF exports are part of ScaleTap Pro — a simple monthly or yearly subscription that auto-renews until cancelled. Your documents always stay yours and always stay readable, subscribed or not.

• New: Dynamic Fill — switch the Area tool to Fill and tap inside a room. ScaleTap traces the walls into an ordinary area measurement, on vector and scanned plans alike. Close a gap with Add Boundary, and keep or deduct the openings it finds with one tap. • New: Find Similar — in the Count tool, frame one outlet, door, or fixture and ScaleTap finds matching symbols on the page or across all pages. Adjust the sensitivity, turn on More angles for rotated symbols, and review the matches before anything is added to your count. • New: Squeeze your Apple Pencil Pro to open a quick color palette for the tool you're using. Set Squeeze to the contextual palette in iPadOS Settings → Apple Pencil. • Fixed flattened PDF and XFDF exports placing measurements in the wrong position on rotated pages. If you exported XFDF from a rotated page in an earlier version, re-export it with this update before sharing or re-importing it. • Measurement values now display with your region's decimal separator, and every number field accepts a decimal comma. • Export fixes: labels near a page edge no longer overlap, text callouts and angle/volume labels stay on the sheet, workbooks with very long notes open in Excel, and documents calibrated only with scale regions export totals and scale provenance. • Replacing a document's PDF now keeps the original until the replacement is safely saved. • Restore Purchases reports clearly what happened, and you can opt out of usage analytics in Settings. Dynamic Fill and Find Similar are part of ScaleTap Pro.
