WarpRun Loom Planner

WarpRun is an offline production planner for handweavers who want the numbers settled before yarn reaches the warping board. It bridges the gap between a finished-cloth idea and a dressed loom without trying to replace your weaving draft software. Enter finished width and length, piece count, sett, loom capacity, reed, shafts, draw-in, shrinkage, take-up, loom waste, sampling, fringe, and winding-bout size. WarpRun converts them into on-loom width, exact warp ends, warp length per end, total warp yardage, estimated weft yardage, winding bouts, and approximate heddle demand per shaft. Build a color allocation for the warp with percentage, yarn on hand, and cost per 100 yards. WarpRun reconciles the final end count by color, estimates yardage and material cost, and flags shortages before you start winding. It also checks loom width, color allocation, fringe allowance, and oversized bouts. The Reed view generates an easy-to-follow dent repeat from your target EPI and reed dents. The Production Brief collects finished size, warp chain, reed repeat, winding plan, color requirements, checks, and bench notes. Export a named PDF or CSV through Apple's system share sheet for the studio, class, or collaborator. Projects stay on your device. WarpRun has no account, subscription, advertising, analytics, tracking, cloud service, social feed, marketplace, or Gobling Company server upload. It is a one-time purchase. WarpRun is a planning aid. Yarn behavior, structure, finishing, tension, and loom setup can change actual take-up and shrinkage. Weave and finish a representative sample, verify yarn quantities and loom limits, and use your own weaving judgment before committing a production warp.
