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?

About

Knitting Row Counter

Features
Read full description

You put the needles down. When you pick them up, which row were you on? Guess wrong and you rip back to find out. Purlmark holds the row — and it holds what the row says, because it reads the pattern you already bought. Paste it in, or open the PDF. Purlmark finds the rows, the repeats and the nested repeats, then tells you what to knit on the row you're on. No re-typing, no counting in your head, no losing your place when the phone locks. MADE FOR THE ROW YOU'RE ON • Tap anywhere on the screen to count. One hand, needles in the other. • The instruction for this row sits under the number, so you stop flipping back. • Repeats are walked for you — "Rows 9–40: repeat rows 1–8 four more times" becomes "1–8 · 2/5" and it counts down. • Undo is one tap. Nothing is lost because you tapped twice. BEFORE YOU CAST ON • A gauge calculator that tells you how many stitches to cast on for your hands, not the designer's. • Log the yarn you have and Purlmark says whether a pattern is covered, or how many skeins short you are — before you start, not halfway up a sleeve. YOUR OWN PATTERNS • Open a PDF you bought. A ruler sits under the row you're on and follows you down the page. • Photograph a paper pattern and Purlmark reads the rows off it. • Written for several sizes? Pick yours and every row reads in your size only. ON YOUR WRIST • Count from the Apple Watch and the row is on your phone when you pick it up. YOURS, ON YOUR DEVICE • No account. No server. Nothing is uploaded — not your patterns, not your photos. • Make a copy of everything in one file, and put it back on a new phone. Purlmark Pro is a single purchase, not a subscription. The free app counts one project and reads patterns you paste, with no time limit and no advertising. What you already counted stays open either way.
