AccuScale vs TrueDim

AccuScale turns your iPhone or iPad into a professional measurement tool for construction plans, architectural blueprints, and job-site photos. Whether you're a contractor verifying room dimensions, an architect reviewing drawings on-site, or a designer estimating material quantities — AccuScale delivers precise real-world measurements in seconds. No tape measure. No scale bar math. No guessing. HOW IT WORKS: 1. OPEN — Import any JPG, PNG, or multi-page PDF blueprint from your files, or photograph a physical plan with your camera. 2. CALIBRATE — Tap two points on any element with a known length (a door, a wall, a standard feature). Enter the real measurement and AccuScale locks in your scale. 3. MEASURE — Tap any two points on the plan. AccuScale instantly calculates and displays the true real-world distance. 4. ANNOTATE & EXPORT — Label each measurement, color-code by area or trade, and export a finished image with all lines and dimensions drawn directly on the plan. KEY FEATURES: MULTI-FORMAT SUPPORT Open JPGs, PNGs, and multi-page PDFs. Navigate page by page through full blueprint sets. PRECISION CALIBRATION Calibrate against any known reference on the plan — no printed scale required. A clear CALIBRATED badge confirms you're ready to measure. INSTANT REAL-WORLD MEASUREMENTS Tap two points, get the answer. Every measurement is calculated automatically from your calibration. FOUR UNIT MODES Switch between feet, inches, meters, and centimetres at any time. All existing measurements convert automatically. COLOR-CODED ANNOTATIONS Organize measurements by room, trade, or category using 8+ color options and custom text labels. FULL PDF BLUEPRINT SUPPORT Open multi-page PDF documents and measure on any page. Pinch to zoom, pan to position.

Most PDF tools treat a sheet like a page of text. TrueDim treats it like what it is — linework at a scale, with a job riding on the numbers. DIMENSIONS WITH A SPINE • Witness legs with per-leg trims, five cap styles, and endpoint tags (VIF, AFF, CL and friends) • Multi-reading dimensions with a live readings table • Stable D-numbers and a dimension schedule that jumps to any dim on the sheet VERIFY AGAINST THE SHEET • Tap a printed scale note to adopt it • Tap a printed dimension to capture it as a live dimension • No text layer? Calibrate with two snapped clicks and a known length SNAPS TO THE REAL LINEWORK • Endpoints, intersections, and perpendicular tracking are read from the sheet's own vector geometry — the mark lands where the line actually is CHECK SETS THAT ROUTE THEMSELVES • Identity-locked ink for every reviewer • Move a set on and the work orders on that drawing follow the routing • Email notifications and the in-app Check Sets inbox keep the review moving without paper on anyone's desk ONE FILE, EVERY DEVICE • Marks live inside the PDF itself — a sheet marked on iPad opens live and editable on the desktop apps, and back again • Apple Handoff: an open review follows you between your devices THE ORIGINAL STAYS PRISTINE • Autosave writes to a verified working copy; the pristine sheet is never rewritten • Export flattened for the record, editable for the next reviewer, or clean Full markup kit: pen, highlighter, regions, polylines, polygons, clouds, callouts, text, photos, stamps, counts, and areas — with per-tool remembered styles and undo/redo everywhere.
