Type a serial or scan the plate to date any vintage Singer in seconds. Pro unlocks dollar value estimates and live eBay listings, and Lifetime exports PDF appraisals.
You see it across the room. An old Singer in the corner of an estate sale, price tag flipped face-down. Featherweight? Common treadle? The difference is hundreds of dollars. You have sixty seconds to decide, and the next picker is already walking over.
SewSnap turns your iPhone into an instant expert. Frame the serial plate and the camera reads the engraved digits, or just type the serial number yourself. SewSnap cross-references official ISMACS production records and returns the exact year of manufacture, factory of origin, and model family, usually in seconds. No spreadsheets, no rabbit holes, no guessing.
Brands supported: Singer (exact year via ISMACS records 1900 to 1971), plus Bernina, Pfaff, Husqvarna, Husqvarna Viking, White, New Home, Elna, and Brother at decade-level precision.
WHAT YOU LEARN IN SECONDS
Exact manufacture year, decoded from official serial-number production records, not crowdsourced estimates. Know whether your machine rolled off the line in 1923 or 1953.
Factory of origin. Elizabethport, Clydebank, Kilbowie, Bridgeport, and the other major facilities in the production tables. Provenance in one tap.
Model family. From the workhorse 66 to the precision 201 to the beloved 15. SewSnap maps serial ranges to the models that actually shipped.
The machine's story. A short, plain-language history of your model, free on every identification.
Featherweight alert. SewSnap auto-detects Singer 221s and other cult collectibles the moment a scan completes. Because finding one deserves a moment.
WHAT PRO ADDS
Dollar value estimates, and the factors that move them: condition, variant, accessories. Price with data, not hope.
Live eBay listings for your exact model, one tap away, so you can sanity-check the current market yourself.
Your full collection. Save every machine you identify, track its estimated value over time, and on Lifetime, export a clean PDF appraisal for your records, your insurer, or your buyer.
