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.
2) Calibrate
Pick two points, enter a known distance, and lock scale for accurate measurements.
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.
We’ll email only about the macOS launch. No spam.
