iPad-first • Apple Pencil workflows • Built for AEC teams

Measure plan PDFs on iPad.

Built for AEC field teams: import a plan, calibrate scale, place linear measurements, and export a flattened PDF + CSV for fast handoffs.

The 60-second workflow your crew will actually use

ScaleTap is intentionally measurement-first. You don’t need a bloated toolset to get accurate numbers in the field.

1) Import

Bring a plan PDF in from Files and open it reliably.

Jobsite-ready Offline-friendly

2) Calibrate

Pick two points, enter a known distance, and lock scale for accurate measurements.

Per-page or default scale ft/in + m/mm

3) Measure + export

Tap → drag → done. Then export a flattened PDF and a measurement CSV.

Made for AEC: pencil-first, low-friction, dependable

When you’re walking a jobsite, the workflow has to be instant. ScaleTap keeps tools compact, keeps scale visible, and keeps your export predictable.

  • Measurements: linear tool + scale calibration (v1).
  • Markups: pen, highlighter, arrow, rectangle, and text callout.
  • Tool presets: save a few repeatable styles (minimal “tool chest”).
  • Exports: flattened PDF and CSV so anyone can open the results.

Measurement-first workflow on iPad: calibrate, place, review, export.

Built for the PDFs field teams actually open

ScaleTap is designed for scanned drawings, vector plans, and multi-page sets common in construction review. Actual speed depends on device model, PDF structure, page count, and embedded imagery.

Scenario Typical file range Best fit
Single trade review 10–75 pages • mixed vector/scanned sheets Fast field review, markup, and export
Multi-page field set 75–300 pages • larger drawing packages Best on recent iPad hardware with representative job PDFs

Trust and accuracy, by design

New app or not, the outputs have to be dependable for field workflows.

Calibration-first

Scale calibration is part of the core flow so measurements don’t become “guesswork.”

  • Calibrate per page when needed
  • Sanity-check with a known dimension

Predictable exports

Export a flattened PDF so markups and labels look consistent across viewers.

  • Great for email + print
  • Include CSV for quick totals

Offline-friendly workflow

Job sites are messy. Core workflows are designed to work without connectivity.

  • Open, measure, mark up, export
  • Purchases/restores require internet

macOS is next

We’re building ScaleTap iPad-first, and keeping the architecture macOS-ready. Join the waitlist to get early access when the Mac version is ready.
