ImageMeter puts measurements and notes directly into your photos. No more hand-drawn sketches that nobody understands: take a photo on site, draw the dimensions where they belong, add notes, detail images, or audio notes, and send a clear document to your clients and colleagues. ImageMeter is used by tradespeople, carpenters, kitchen and interior designers, property managers, sign makers, insurance assessors and many more. ENTER MEASUREMENTS YOUR WAY • Bluetooth laser meters: send measurements straight into the image. ImageMeter supports most laser distance meters with Bluetooth and, where the device allows it, triggers measurements remotely (https://imagemeter.com/manual/bluetooth/devices). • Measure in the image: set a reference, such as a known wall size, a sheet of paper or a known length, and ImageMeter calculates lengths and areas, even on surfaces seen in perspective. • Or simply type in the values from your tape measure. TOOLS FOR EVERY JOB • Lengths, areas, angles, circles and rectangles • Measurement strings and polylines • Counting tool • Text notes, freehand drawings and arrows • Audio notes and detail pictures inside the image • Line styles, colors, font sizes and arrowheads • Brightness, contrast and saturation for poorly lit photos PDF PLANS AND FORMS Import floor plans and drawings from PDF files. ImageMeter takes the scale of the drawing into account, so you can measure right on the plan. Fill your PDF forms directly in the app. EXPORT AND SHARE • Images as JPEG or PNG, annotated PDF documents and PDF reports • Data tables for bills of materials or measurement logs, ready for your spreadsheet • Editable image files for other ImageMeter users YOUR CLOUD, YOUR DATA Sync your images with the cloud storage of your choice: OneDrive, Dropbox, Google Drive, your own Nextcloud/WebDAV server or SFTP. Continue working on your office computer with ImageMeter for macOS, Windows and Linux. FREE, PRO AND BUSINESS ImageMeter is free to download and try. The free version has a limited number of measurements per image, and exported images carry a watermark. Pro (one-time purchase) adds: unlimited measurements, no watermarks, PDF import and annotation, subfolders, unlimited range for Bluetooth laser meters, circles and rectangles, measurement strings, counting tool, perspective length measurement and audio notes. Business (monthly or yearly subscription) includes everything in Pro, plus image sync between your devices and backup to your own cloud storage, your company logo on images, data table export and layers.

Calque
Read full descriptionHide full description
Calque draws precise floor plans of your house and gives every room its exact area, measured the way a notary, an architect or a planning office will ask for it. Drag out walls with your finger, then set any length, thickness or position to the millimetre. Calque finds the rooms between the walls by itself: you never draw a room, so its area can never disagree with the walls around it. Free to download, with no limit on levels or rooms: every tool and every area standard are yours. Calque Pro is one purchase, with no subscription, for what you hand on: the PDF to scale, the area schedule as CSV and flooring quantities. Whatever joins Pro later is included. AREAS YOU CAN HAND OVER • Net floor area, surface habitable (loi Boutin), surface Carrez and surface de plancher, per room, per level and for the whole house • Rooms measured to the finished face of each wall, linings included • Give each room a type, from bedroom to laundry, garage or terrace, or just a name: call it “Landing” and it counts as a corridor • A wall that stops a few millimetres short leaves its room open. Calque marks the gap and closes it in one tap • Each room's floor in its doorways and its skirting length, for a flooring quote (Pro) WALLS THAT BEHAVE LIKE WALLS • Wall kinds, each with its own thickness, and a build-up on each side, such as plaster or insulation, counted into the rooms • Corners shared by the walls that meet there: drag a wall and its neighbours follow • Curved walls for a bay or a round tower • Chimney breasts, pilasters and niches, and railings round a terrace or a stairwell • Doors, windows, columns, stairs and steel beams by profile, with their bearings and span • Furniture for the kitchen, bedroom and bathroom, with its clearances drawn DIMENSIONS THAT HOLD • An automatic dimension ladder along the walls, plus chains you place yourself • Freeze a dimension and the plan keeps it: type 3.40 m and the wall moves to match LEVELS AND BUILDINGS • Ground floor, upstairs, cellar, and a garage or an annex as a building of its own • Show the level below as a ghost while you draw, and align a level onto it • Draw a floor opening as any shape: the stair shows through it, and it comes off that floor's area • Set north from one facade, and see which way each window and room faces EXISTING AND PROPOSALS • Keep the house as surveyed and redraw any number of proposals beside it, in the same file • Compare a proposal with Existing: what to demolish in yellow, what to build in red, and the change in every area THE PLOT AND THE PLU (FRANCE) • Draw the parcel, terraces, pool, trees, drains and supply lines around the house • Type your commune's PLU limits, and Calque checks setbacks, emprise au sol, pleine terre and borehole distances as you draw TRACE WHAT YOU ALREADY HAVE • Import a scanned plan, a photo or a PDF, set its scale from one length you know, and draw over it • Photographed at an angle? Tap the four corners of a rectangle on the sheet and Calque straightens it flat EXPORT TO SCALE (PRO) • A PDF at 1:50, 1:100 or your own scale, with a live preview and a title block filled in for you • The screen and the PDF come from the same renderer, so the print matches what you drew ON YOUR IPHONE, YOUR IPAD AND YOUR MAC A plan is one document in iCloud Drive, open on every device. Pinch to zoom, drag with two fingers to pan, and pick up on the Mac where you left off. PRIVATE BY DESIGN No account, no subscription, no tracking. Your plans stay in your own files. Calque is available in English and French.

Verdict
The clearest difference is update cadence: Calque at daily against ImageMeter's every 5 days. ImageMeter's advantage is iOS requirement (16.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
