Scales HD vs ArchitectScaler

Scales HD puts a real architect's and engineer's scale rule in your pocket, drawn at true physical size on every iPhone and iPad, so a millimetre on screen is a millimetre on your drawing. Around it: a CAD, Room Scan, a PDF blueprint reader, a construction calculator, notes and more. TRUE SIZE ON EVERY DEVICE • Exact screen density for every iPhone, iPad and iPhone Duo model • Zero at the screen edge or the device edge; optional calibration TRIANGULAR SCALES, JUST LIKE THE REAL ONE • Turn the scale to its other sides; all four edges on each, the original artwork's grooves and faces • One tap prints the US ↔ metric equivalent beside every scale: 1:48 next to 1/4" = 1'-0" • Two measuring lines read in both edge scales at once, with snapping EVERY SCALE YOU USE • US architectural 1/32" to 12" = 1'-0"; engineering 1" = 10' to 120' • Metric 1:1 to 1:10000, civil and survey; mechanical; UK and Japanese rules • Enlargements, maps 1:24000 to 1:250000, model rail and kits; read any edge at ×10 or ×100 • Your own scales, any ratio, in your own color CAD • Walls, doors, windows, furniture and dimensions at real size; freehand too • Booleans, trim, extend, fillet, offset, arrays, layers, edit in place • About 700 templates: full project sets, homes, interiors, ADA, landscape, sections, details, MEP • Export true-scale PDF or SVG, PNG, DXF and DWG; open DWG and DXF drawings ROOM SCAN (LiDAR iPhone and iPad) • Scan rooms into floor plans, elevations, a room schedule and 3D models • Stitch rooms, set a measured length, export USDZ, OBJ, glTF, IFC and DXF, or open as a CAD drawing BLUEPRINTS • PDF drawing sets as sheets you can search and bookmark • Set the sheet's scale and measure lengths, areas and counts; mark up with clouds, callouts and stamps • Compare revisions; stand a plan in the room at 1:1 in AR CONSTRUCTION CALCULATOR • Feet-inch-fraction and metric, mixed freely: 5'-3 1/2" + 80 cm • Areas, volumes, diagonal, pitch, stairs, circles; a tape of your calculations NOTES THAT SKETCH • Lists, checklists and a full row of symbols, fractions and units over the keyboard • Drop in pictures, PDF pages and CAD drawings, then move and size them; text flows around • Quick sketch stickies: draw with a finger or Apple Pencil in any color and pen VOICE • A microphone on every screen: "use 1 to 50", "3 feet 4 inches plus 2 feet", "place a queen bed against the north wall". Understood on the device MORE TOOLS • Unit converter: 11 families, 94 units • Scale converter: drawing ↔ real size, redraw at another scale, find a drawing's scale • Protractor: read an angle on paper at true size, between two surfaces by tilt, or on the iPhone Duo's hinge, with the supplement, the miter and the saw setting • Spirit level with the original bubble, compass, tape, cutting board, haptics MADE FOR iPHONE DUO • Closed, every tool fits the outer screen around the camera; open, the big screen; half open, the calculator, level, compass, protractor and blueprints keep off the fold; the hinge itself is a protractor iPhone and iPad, iCloud sync between your devices.

ArchitectScaler turns your iPhone and iPad into a scale ruler, a drafting calculator, and the small toolbox of conversions architects, designers, and students actually reach for. No triangular ruler, no clunky calculator, no "calculate" button - you type, and the answer is already there. Version 2.0 opens on a Home screen of tools. Tap one and you are working. THE CONVERTER Set a scale once, then keep a live ledger of dimensions. Type a real-world length to get the drawing length, or type a drawing measurement to get the real thing - both directions, instantly. Name any row ("North wall", "Door", "Site") so a list of numbers reads as a list of things. Your rows, scale, and units are saved between launches. FEET AND INCHES, PROPERLY Type 12'-6 1/2" the way you would write it. Scales like 1/4" = 1'-0" are first-class, and a keyboard row puts the ' " - and / marks one tap away. Change a unit and the app converts the value rather than re-reading the same digits. THE TOOLS Find scale from a drawing - measure any labeled dimension on a print and get the ratio back, with the nearest named scale offered as a one-tap match. Slope and pitch - convert between 1:20, percent, degrees, and roof pitch, and get the fall over a run. Area and volume - scale squared and cubed, from square millimeters through hectares and square inches through acres, plus cubic meters, feet, and yards. Rescale and print - the copier percentage that takes a drawing from one scale to another, and what a line measures after the change. Sheet fit - whether a plan fits a sheet inside its margins, and the largest named scale that would. ISO A0 to A4, ANSI A to E, and Arch A to E1. Feet and inches - add and subtract lengths in drafting notation without converting to decimal first. Scale bar - generate a printable graphic scale and share it straight into a drawing. Model making - turn a real wall thickness into the nearest card, foam board, or acrylic sheet, and see how far off that substitution puts you. BUILT FOR THE WAY YOU WORK Metric and imperial: mm, cm, m, km, in, ft. Metric, architect, and engineering scale presets, or type any ratio you like - 1:48 and 1:37.5 are both fine. iPhone and iPad. Light and dark, following your system appearance. No account, no ads, no tracking, no data collection. Every calculation stays on your device. Built by an architect, for architects, interior designers, engineers, students, model makers, and anyone who works from a scaled drawing.
