Length, area, count, angle, volume — placed with Apple Pencil, snapped to the drawing.

Why ScaleTap

Built around the result, not a crowded toolbox.

Every tool earns its place. Everything else stayed out.

Trust the scale

A wrong scale is a wrong bid. Calibration stays visible, per page or per region, so every number traces back to a scale you set.

  • Distance and scale-bar calibration
  • Presets and multiple scale regions

Stay on the drawing

Tools live at the edge of the screen, not on top of your plan. Pencil draws, finger pans — the way iPad should work.

  • Direct measurement placement with snapping
  • Markup and editing without modes or panels

Send proof, not screenshots

Flattened PDFs open cleanly anywhere. XLSX and CSV drop straight into your estimate. XFDF keeps annotations portable.

  • Flattened PDF, full set or selected pages
  • XLSX, CSV, and XFDF data
Built for the job

Made for the people who carry the plans.

Whether you're checking one dimension on site or taking off a whole bid.

Field verification

Check dimensions, document issues, and send marked-up proof before you leave the site.

Common questions

Know what to expect before you install.

Does ScaleTap work without an internet connection?

Yes. Opening PDFs, measuring, marking up, and exporting all work offline. Only purchases and restores need connectivity.

Can I try ScaleTap with my own construction plans?

Yes — that's the best way to judge it. The yearly plan includes a 7-day free trial, so you can run a real takeoff before paying anything.

Which export formats are available?

Flattened annotated PDFs (with an optional measurement summary), plus XLSX, CSV, and XFDF measurement data.

What happens if I don't subscribe?

Your PDFs stay yours. You can keep importing, opening, navigating, and marking up documents for free — Pro only gates measurement, calibration, and data export.

Do I need to create an account?

No. ScaleTap works without an app account or cloud workspace. Import a PDF from Files and start working on your iPad.

Do your next takeoff where you open the plan.
