Paste in a pattern, tell Pearl your swatch, and she works out every stitch and row so it comes out your size — at your tension, in your yarn. No frogging. No notebook full of sums.




Knit a small swatch and pop in the stitches and rows you get over 10 cm. That's all she needs to start — metric or imperial, your call.
Paste the pattern in and Pearl reads it for you, filling in the numbers herself. You just glance over and check she's got them right.
She re-knits every count to your tension — cast-on, rows, shaping and all — and shows you exactly what changed. Then the needles are yours.
Watched Pearl work? She's ready when you are — free to regauge, no account needed.
Regauging is the heart of Slowspun, and it stays free for good.
Pro opens the rest of Pearl's workshop.

Paste a knitting pattern or open a PDF, add your swatch, and Pearl re-knits every count to your gauge —
cast-on, rows, shaping and all.
As many as you like, for nothing.

Join the testSlowspun is a knitting companion app for iOS and Android. Its main job is regauging — recalculating a knitting pattern's stitch and row counts so the finished piece matches your own gauge — along with tools to organize your gauges, needles, yarns, measurements, and patterns.
Regauging is adjusting a knitting pattern to your personal gauge — how many stitches and rows you knit per inch or centimeter. Because every knitter's tension is a little different, working a pattern at your own gauge is what keeps the finished garment the intended size. Slowspun does that recalculation for you.

Slowspun is a small, unhurried app made by a solo designer and a very relaxed sloth named Pearl. It began with a frustration every maker knows: the math. Every pattern is written for someone else's gauge, and fixing that by hand means a notebook full of arithmetic and the occasional ruined sweater.
So Pearl took over the sums. You bring the yarn and the patience; she'll keep the numbers straight, at her own gentle pace.
"Hand me a pattern and your swatch, and I'll quietly redo the arithmetic — so a column of numbers is never the reason a project goes back in the basket. Come knit at your own pace. I'll keep the counts."— Pearl
