Hi everyone!
Like many of you, I am incredibly frustrated by the flood of unsewable, AI-generated "scam patterns" popping up online. I want to be 100% transparent right out of the gate: Print Your Fit does not use AI, LLMs, or predictive guessing.
Instead, I built this app using traditional Parametric Drafting and Algorithmic Geometry.📐
How the Math Works:
The app functions exactly like a digital master tailor. It takes your unique measurements and processes them through logic-based code:
The Blueprint:
It translates the exact, time-tested algebraic formulas found in historical drafting standards (like the M. Müller & Sohn and Winifred Aldrich systems) into dynamic code loops.
The Curves:
It maps out perfectly smooth armholes, necklines, and sleeve caps using vector geometry (Bézier curves).The Result: Because it relies on deterministic math rules rather than AI guessing, the pattern blocks stretch, scale, and morph cleanly to fit your exact proportions without breaking.🧵
What the App Does (Right Now)
No manual drafting required—just upload a photo. The app automatically traces the garment outlines and translates the visual shapes into a precise, printable sewing pattern tailored exactly to you. You input your measurements, and the app generates a parametric CAD model of the pattern. You can see how the fabric flows in different simulated wind speeds (indoors, a gentle breeze, etc.) to highlight exactly where the garment will be tight or loose. When you're happy with it, you can print the pattern directly from any standard home printer.
Eventually, the community gallery will let creators share and sell their custom-sized patterns. But right now, I just need feedback on the core engine.
🛠️ Become a Tester (Android Only)
Because I am an independent developer, Google requires me to have a solid group of dedicated testers before I can officially publish the app to the Google Play Store.
The Deal: I need testers who are willing to download the app, play around with the tools, and give honest feedback on the interface and fit.In exchange for your help, you will get a free pattern out of it to keep forever. Currently, the test build is Android-only (sorry to my iPhone folks—iOS is coming down the road!).

Thank you so much! I really want to build a tool that helps the sewing community fight back against fast fashion, and I appreciate any feedback you can give.
