PatternPlot vs patanQ

PatternPlot turns a paper sewing pattern into an editable, true-scale vector on your iPad — then grades it into a full size run you define, deterministically. Tracing a pattern got easy years ago. Grading — turning one size into a trustworthy run of sizes — is still the hard, trust-sensitive job. PatternPlot is built around that job, on device, with geometry you can audit. FREE — real work, no subscription • Photograph or import a paper pattern and trace it with Apple Pencil (or finger + numeric entry). • Import your own vector artwork (SVG) at true scale — free, because it is how you get your work in. • Edit true-scale vector pieces: add seam allowance per edge, notches, and grainlines. • Export true-scale tiled PDFs and A0 — with a 50 mm calibration square and registration marks so your print is exactly to scale. • Grade YOUR piece: mark a reference point and an axis, type how much each size grows, and see the whole run nested on screen. • A quality report on every graded size: drift beyond the safe grade range, collapsed edges, and self-intersections. • Export the base size — the size you drafted — at any time. No purchase is required to do any of this. Basic export is never locked behind a paywall. PRO GRADING — the paid tier • A tiled PDF for every size in your run. • A vector outline of every piece at every size. • A nest of the whole run on one sheet. • Every piece of the garment in each file, not just one. • A spreadsheet of what every declared seam measured, size by size. • Your grade corrections saved to a file, so another garment can use them. The vector files carry the stitching outline only — no seam allowance, notches or grainline. Reading a saved corrections file back into a pattern is free; only writing one is Pro. HONEST BY DESIGN The grade is deterministic geometry computed on your device. AI never touches your measurements: no coordinate, seam allowance, notch position, or graded measurement is ever produced by a model. PatternPlot also tells you when a size drifts beyond a safe grade range, so you can re-check proportions before cutting fabric. We describe this as garment-aware grading — not a fit guarantee. REQUIRES: iPad on iPadOS 17 or later. Apple Pencil recommended but not required. — Pro Grading subscription: $79.99/year after a 7-day free trial. Payment is charged to your Apple ID at confirmation of purchase. It renews automatically unless turned off at least 24 hours before the end of the period; manage or cancel anytime in your Apple ID Account Settings. Trace, vector edit, seam allowance, notches, grainline, and tiled/A0 PDF export are free and do not require a subscription.

Draft real sewing patterns right on your phone. Making patterns for sewing and handmade projects usually means spreading out large sheets of paper and measuring everything by hand. patanQ lets you do it all on your iPhone or iPad screen instead. Combine a wide range of shape tools to draft exactly the pattern you need, quickly and easily. --- **Shape Tools** 7 shape tools let you draw anything from simple pieces to complex parts. - Rectangle: sharp corners, no rounding - Trapezoid: automatically generates a clean, symmetrical trapezoid - Circle & Ellipse: adjust width and height independently - Triangle: tap 3 points to draw any triangle - Line: use for seam allowances or guide lines - Curve (Bezier): draw smooth curved pieces **Editing Shapes** - Drag to move any shape freely - Pull the handles to resize - Use the rotation handle to adjust the angle - Flip horizontally or vertically - Duplicate a shape to quickly reuse a piece **Paper Sizes** 10 sizes — A1–A5 and B1–B5 (JIS) — in either portrait or landscape. Draft patterns at true size, ready to print exactly as designed. **Dimension Lines** Shows the length of every edge (in mm) right on the canvas, so you can check your measurements as you draft and avoid sizing mistakes. **Print & Export** Export any pattern as a PDF. - AirPrint: print wirelessly to your printer at home - Convenience store printing: upload the PDF to a Japanese network print service and save the QR code it issues — a handy way to print large sizes (available when using the app in Japanese) - Share PDF: send the file however you like — AirDrop, email, cloud storage, and more **Manage Multiple Patterns** Save and organize as many patterns as you like. Renaming and deleting are just as easy. Reopen an unfinished pattern anytime and pick up right where you left off. --- Serious pattern drafting, made simple. Bring it into your everyday handmade projects.
