A row counter that follows your crochet and knitting patterns

Bring in the PDF and photo patterns you already own. Yarnstep splits them into rows, keeps only your size, and moves the counter each time you tap Next row.

From a PDF to the row you are on

Three steps, then you only look at one row at a time. Your original pattern stays one tap away.

  1. 1

    Import a pattern you own

    A PDF from Files, a photo of a printed page, or a share from Safari.

  2. 2

    Pick your size

    “36 (40, 44) sts” becomes 40 sts everywhere if you knit the middle size.

  3. 3

    Follow it row by row

    Each row shows its steps, the stitch count to end on, and the line it came from.

What sits next to your yarn

The parts of a pattern you usually track on paper, kept on one screen.

Counters you never pay for

As many row, stitch and repeat counters as you like. Count from the Lock Screen widget, a Live Activity, or the volume buttons when your hands are full.

Abbreviations explained on tap

Tap sc2tog or ssk for a plain definition and a stitch diagram. Switch between US and UK terms.

Repeats laid out in order

“Rep rows 3 to 6 four times” turns into the sixteen rows you will actually work, and the counter keeps track.

Patterns stay with the person who bought them

Yarnstep has no sharing button for imported patterns, does not scrape designer sites, and never trains anything on your files. Each pattern keeps its designer's name and a link to buy it.

Questions about Yarnstep

Which patterns can I bring into Yarnstep?

Patterns you own as PDFs or photos. You can import from Files, from your photo library, or share a PDF straight from Safari. Yarnstep has no pattern store and never fetches patterns from designer sites.

What happens with size brackets like 36 (40, 44) sts?

You pick your size once. Yarnstep keeps only your numbers in every bracket, so each row shows the one stitch count you need.

Does it understand repeats?

Yes. Lines such as “rep rows 3 to 6 four times” become real rows in order, and the counter moves through them as you tap Next row.

What if a step is read wrong?

Every step shows the original line from your pattern page next to it. Steps Yarnstep is unsure about are flagged, and you can edit any step.

What do I get without paying?

Unlimited row and stitch counters, the PDF viewer with highlighter and row ruler, the abbreviation dictionary, your yarn stash, and 3 guided pattern imports. Pro is $4.99 a month or $29.99 a year.

Does it work on iPad?

Yes. Yarnstep runs on iPhone and iPad. With Pro, your library, counters and place in each pattern sync between them through iCloud.
