The in-store buying copilot for knitters and crocheters. Scan any ball band, pick your project, and get a confident skein count — with the reasoning behind every number.
Point your camera at a ball band. SkeinSense reads the brand, yardage, weight and fiber in one shot — no typing in the store.
Not just "10 skeins" — the math, the safety buffer, and the dye-lot advice, in plain English. Tap "show the math" any time.
If your stash already holds 4 skeins of that yarn, SkeinSense says "buy 6 more" — and warns you to blend the dye lots.
Photograph the pattern page and its stated yardage and gauge drive the estimate. Pattern says 1,350 yds? That's what we use.
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.
Fully. Crochet uses roughly 25% more yarn than knitting, and SkeinSense applies that automatically — and shows the adjustment in the explanation.
Every estimate says which gauge it assumes and flags when a swatch matters. Scanned pattern gauges are used directly.
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.
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.
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.

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