PlanMeasure
Read full descriptionHide full description
Turn any floor plan, blueprint, site map, or aerial photo into a precision measuring tool. Import a plan from Files, Photos, or directly from Apple Maps, set the scale with two taps on a known reference, and then measure every distance, area, and angle without leaving your iPad or iPhone. CALIBRATE ONCE, MEASURE FOREVER PlanMeasure works on any image. Drop in a PDF blueprint, a photo of a printed plan, or pull a satellite view straight from the map. Tap two points on a known reference (a door, a parking space, a property edge), enter the real-world length, and every following measurement is calibrated to the same scale. EVERYTHING YOU NEED TO MEASURE ⢠Ruler ā tap two points, see the distance instantly with unit-correct labels ⢠Polyline ā measure complex paths and chained distances point by point ⢠Area ā trace a polygon, get the total area with Shoelace-formula precision ⢠Angle ā tap three points to measure any angle, with live arc preview ⢠Protractor ā drop a draggable, rotatable protractor anywhere on the plan ⢠Apple Pencil ruler ā draw straight lines along the native iOS ruler ANNOTATE WITHOUT LEAVING THE PLAN Add lines, rectangles, ellipses, freehand sketches, and industry-standard symbols (furniture, machinery, solar arrays) directly on your plan. Organize them in layers ā show, hide, or fade individual layers as needed. The wipe-eraser carves through anything (drawings, symbols, measurements) with clean masking, not destructive deletes. BUILT FOR REAL WORK PlanMeasure is the tool architects, builders, solar installers, surveyors, landscapers, and real estate professionals use on site: ⢠Quick wall-to-wall checks during a survey ⢠Solar panel area calculations on satellite imagery ⢠Square footage estimates for offers and quotes ⢠Site distance planning for landscaping ⢠Furniture placement on existing floor plans EXPORT & SHARE Export your annotated plan as PDF or PNG with a clean footer showing scale, date, and project name. Send it via Mail, Files, AirDrop ā or feed it into your usual workflow. PRIVACY FIRST Your projects stay on your device by default. iCloud sync is opt-in during onboarding ā you decide whether your plans live only on this iPad/iPhone or sync between your devices via your private iCloud account.

TrueDim is the measurement-grade PDF markup app for people who work from drawings. REQUIRES A FETZER WORK ACCOUNT TrueDim is the field and shop tool for Fetzer Architectural Woodwork. Signing in with a Fetzer work email is required to use the app. Accounts are issued by the company ā there is no public sign-up, and the app cannot be used without one. Most PDF tools treat a sheet like a page of text. TrueDim treats it like what it is ā 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 ā 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 ā 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 ā with per-tool remembered styles and undo/redo everywhere. YOUR DRAWINGS STAY ON YOUR DEVICE Once you have signed in on a device, drawing and measuring keep working with no network. Your documents and marks are stored on the device; signing in carries only your name and work email. Built by Fetzer Architectural Woodwork ā for people who build from drawings.

Verdict
The clearest difference is in-app purchases: TrueDim at none against PlanMeasure's 1. TrueDim also leads on update cadence (every 4 days vs every 2 months) and iOS requirement (17.0 vs 26.2). On price, ads and device support there is nothing between them.
