Spool: For Knitters
Smart Patterns & Row Counters
Free · In‑App Purchases
Made to support the creative process from cast on to cast off.
Spool was built by a knitter who was tired of scribbling row counts on PDFs, circling sizes in every step, and constantly losing track of progress within patterns.
Upload your knitting pattern, create a project, and work through it step-by-step, section-by-section — just hit 'Next Row' and keep knitting.
Anywhere there's a repeat, there's a built-in row counter integrated with the full project. Size-specific instructions, stitch counts, and repeat tracking are all handled. See all your WIPs in one place, track your knitting hours, and finally put that yarn stash to work.
FEATURES
Step-by-step interactive patterns — work through your project row by row, with built-in row counters & repeat tracking and your size pulled through to every step
Colorwork & cable charts — your pattern charts directly in the app. Customize colorwork with your actual yarn colors, and track your place with automatic highlighting on your current row
Knitworthy: add your measurements (and those of the people you knit for), all that data in one place — plus we'll recommend a size based on the project's recommended ease
Standalone row counter — for quick projects and one-off needs
Materials: Needles and Yarn Stash — catalog your yarn and materials so you can finally utilize that stash
Yarn substitutions: want to use a different yarn than the recommended? We'll give you a starting point for your needle size, based on Ravelry data
Time tracking — find out exactly how long your sweater actually took
Ruler — measure your ribbing without hunting for a tape measure
Widgets and Live Activities: work your project from your home screen or lock screen
Glossary — definitions and tutorials linked directly to terms in your pattern

Terms of Use: https://spoolhq.co/terms
- Pattern library improvements: Sort your Pattern library by recently knit, name, designer, or date imported, or use the new search bar to search by name or designer. Pattern cards now carry their designers too!
- Reference instructions: In patterns that have instructions that reference past steps (e.g. “Work the second sleeve in the same way”), the app will show the past steps inline and enable knitters to advance through them as they did with the original steps.
- Misc fixes: Charts written top-down are now displayed in the correct orientation in the interactive viewer. Needles are correctly removed from “in use” when a project is completed. When the app detects a long session without progress, it now gives an option to pause the session at the time of the last row change.
- Performance updates & iOS version compatibility: Scrolling on pages like Patterns and Project instructions is smoother. Log in for iOS versions lower than 26 is far more stable. Some main UI elements that rendered incorrectly on iOS 27 have been fixed.
