LeatherPulse: Craft Studio is an artisan leatherworking suite for leathercrafters, cordwainers and hobbyists. Pattern geometry, stitch pitch, thread ratios and project costs, all offline.
Explore the benchTry the thread labWork out rounded edge allowances, seam margins for leather from 1.0 mm to 4.0 mm, and the total square feet or square decimeters any project demands.
Pick 3.0, 3.38, 3.85 or 4.0 mm spacing, add your layer thickness, and get the exact thread length for hand saddle stitching, so the thread lasts the whole seam.
Convert ounces to millimeters, check temper classifications and balance burnishing mixes of Tokonole, beeswax and gum tragacanth.
Track build timelines, keep step-by-step notes, cost out hardware and materials per item, and save your custom pattern dimensions for the next run.
Fully offline with local storage, no permissions requested, no background tracking, no subscriptions and no paywalls.
🪡 We are a small crew of leatherworkers and app builders who got tired of scribbling thread math on scrap hide. LeatherPulse grew out of real workshop frustration.
📐 Our mission is simple: give every leathercrafter, from cordwainers to weekend hobbyists, precise tools that respect the craft and the material.
🐂 You get a pattern calculator, a stitch pitch and thread lab, a weight and edge finishing guide, and a project log with cost estimates, all in one app that works fully offline.
🧵 It matters because every mistake in leather is permanent. Accurate numbers save hide, thread, money and the heartbreak of a seam that ends early.
Cut clean. Stitch true. Pulse with the craft.
