About SkeinCheck: Yarn Planner
What can you make with the yarn you already have? SkeinCheck helps you plan crochet and knitting projects around your remaining yarn, without an account or an app cloud service. START WITH YOUR YARN Add only the colors and quantities you want to use now. There is no need to catalog your entire stash. Your own measured yarn use provides the basis for planning. WILL YOUR YARN BE ENOUGH? Estimate how far your yarn will go using weighed rows or matching sample squares. See the amount needed for each color, your reserve and any shortages. Results are estimates based on your inputs. DESIGN STRIPES AND SQUARES Create color layouts for striped rectangles or grids of single-color granny squares. Planning takes your available quantities into account. The output is a material and color plan, not a complete pattern for arbitrary garments. REPLAN WITHOUT STARTING OVER Mark finished rows and squares. After weighing your yarn again, replan the unfinished portion while keeping completed work unchanged. KEEP YOUR PROJECTS WITH YOU Save projects locally and export your plan as a PDF. File backup and restore remain free. Automatic cross-device synchronization is not included. START FOR FREE Use one active project with up to three colors and one saved layout. Calculators, progress tracking, replanning and file backup are included. PLAN MORE WITH SKEINCHECK PLUS An optional non-consumable, one-time in-app purchase unlocks multiple active projects, up to twelve colors per project and additional saved layouts. No subscription and no ads. The app shows the current price before purchase. Core features work offline. Purchases and purchase restoration require a store connection. Restoration works within the same store and store account. Optional error diagnostics are explained in the privacy information. Yarn use varies with materials, technique, tension and finishing. Include a reserve and check your measurements as you work. EXPLORE PLUS BEFORE BUYING Open the read-only six-color example and compare a material plan before and after a new weighing, without changing your projects or yarn stock. Completed and locked pieces are preserved. Plus allows up to twelve colors and twenty saved layouts; existing work stays editable and exportable without Plus.
