SkeinSense estimating 1,600 yards for a medium knit sweater SkeinSense explaining why to buy 10 skeins: 8 needed plus a 15% dye-lot buffer

Never guess in the yarn aisle again

📷

Scan any label

Point your camera at a ball band. SkeinSense reads the brand, yardage, weight and fiber in one shot — no typing in the store.

🧮

An answer that explains itself

Not just "10 skeins" — the math, the safety buffer, and the dye-lot advice, in plain English. Tap "show the math" any time.

🧺

Knows what you own

If your stash already holds 4 skeins of that yarn, SkeinSense says "buy 6 more" — and warns you to blend the dye lots.

📄

Reads your pattern too

Photograph the pattern page and its stated yardage and gauge drive the estimate. Pattern says 1,350 yds? That's what we use.

How it works

Scan the label — or type two numbers off the ball band (yards per skein, grams).
Pick your project — sweater, blanket, socks… or your own saved template, knit or crochet.
Buy with confidence — an exact skein count, the why, and a dye-lot reminder at checkout.

Questions stitchers ask

Is SkeinSense free?

Yes — the estimator, three Smart Scans a month, and a starter stash are free forever. SkeinSense Pro unlocks unlimited scanning, unlimited stash, and the cost & dye-lot tools.

Does it work for crochet?

Fully. Crochet uses roughly 25% more yarn than knitting, and SkeinSense applies that automatically — and shows the adjustment in the explanation.

What if I knit tighter or looser than average?

Every estimate says which gauge it assumes and flags when a swatch matters. Scanned pattern gauges are used directly.

Do I need the app store version?

No — the web app runs in any browser today and does everything the phone apps do. The iOS and Android apps add camera scanning that feels quicker in a shop; both are in closed beta and open to testers now.

How do I join the beta?

Email info@skeinsense.com with the account you'd like added — a Google account for Android, an Apple Account for iOS — and we'll send you in. See the beta section for what to expect.

Beta

Test SkeinSense on your phone

The native apps are in closed testing before public release. Both tracks are invitation-only — send us a note and we'll add your address, usually the same day. Everything is unlocked and free for testers.

Android

Google Play · internal testing

Once your Google account is on the list, open this link on your Android phone and accept the invitation. The app then installs from the Play Store as normal.

iPhone & iPad

Apple TestFlight

TestFlight invitations go out by email, so there's no public link. Send us the Apple Account address you use on your device and you'll get an invite from Apple.

Request an iOS invite →

Not on the list yet? Email info@skeinsense.com with the address you'd like added — a Google account for Android, an Apple Account for iOS.
Two things to expect. The Android link only works for accounts we've added, so it will say the item can't be found until you're on the list — and you must be signed into the Play Store with that exact account. Until Google finishes reviewing the app, it appears under its package name com.liquidmonks.skeinsense rather than "SkeinSense".

Your next project starts with the right number

Free to use, nothing to install, works on your phone in the yarn shop.
