A cozy knitting companion

Knitting your patterns to your gauge.

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.

We sweat the small stitches so you don't have to.

Built by a designer for a knitter who hated the math.

Three steps, then you knit.

1

Tell Pearl your gauge

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.

2

Hand over the pattern

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.

3

Knit at your gauge

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.

FAQ

Questions, answered.

What is Slowspun?

Slowspun 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.

What does "regauging" mean?

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.

Does Slowspun work offline?

Yes. Slowspun works fully offline and needs no internet connection to use. The only time it reaches the network is a quick check with the app store to confirm your purchase status — it uses no server of its own and sends no personal information.

Does Slowspun collect my data or require an account?

No. There are no accounts and no sign-up. Everything you enter — gauges, measurements, setups, yarns, any photos you add, and saved patterns — stays on your device. Slowspun has no analytics, no tracking, and no advertising.

Is Slowspun free? Is it a subscription?

Slowspun is free to download and use, with an optional one-time purchase to unlock the full version. It is a single one-time unlock, not a subscription. Payments and refunds are handled by the App Store or Google Play.

What platforms is Slowspun available on?

Slowspun is a mobile app for iOS (iPhone and iPad) and Android. It is not available as a website or a desktop program.

Is Slowspun for knitting or crochet?

Slowspun is built for knitting — it works with knitting gauge, needles, and patterns.

Can Slowspun read PDF knitting patterns?

Yes. You can import and read PDF knitting patterns in the app, and you can also paste in pattern text.

If I reinstall Slowspun or get a new phone, do I keep the full version?

Yes. Your unlock is tied to your app-store account, so after a reinstall or on a new device Slowspun restores it automatically once you're online, and there is a “Restore purchase” option if you ever need it.

How do I get a refund?

Refunds are handled by the app store you bought from — the Apple App Store or Google Play — following their refund policies. If your purchase is refunded, the full version turns back off.

Made by a passionate designer

Slow down. Let Pearl do the math.

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
