SpecScan tells you what a car is actually worth — instantly, from its VIN, priced against the live market instead of generic book values. Enter any VIN (or scan the door-jamb barcode) and SpecScan decodes the exact year, make, model, trim, and factory options, then values it against real dealer listings for the same car — the way a seasoned dealer prices inventory. Built by an exotic and performance car dealer, SpecScan is tuned for the vehicles mainstream valuation tools get wrong: Porsche, Ferrari, Lamborghini, McLaren, Corvette, Shelby and other performance and collector cars, where options, mileage, and trim can swing value by tens of thousands of dollars. WHAT YOU GET • Real market value with a confidence-rated price range • Comparable listings — actual cars for sale now, with prices, mileage, and links • Deal analysis — enter an asking price and see if it's a good, fair, or over-market deal • What to offer — accept / target / aggressive price points, plus a red-flag "too cheap" line • Options that matter — factory options decoded from the VIN, with resale impact • Buyer guidance — mileage context, history checks, and negotiation tips WHO IT'S FOR • Buyers who don't want to overpay • Sellers pricing a car to move • Enthusiasts and collectors tracking what their car is worth • Dealers sizing up trades and acquisitions Free to download, with complimentary scans every month.

Verdict
The clearest difference is ads: SpecScan VIN Decoder at none against Calculator·'s shown. SpecScan VIN Decoder also leads on update cadence (every 5 days vs every 3 months) and monetization model (free vs free with in-app purchases). Calculator·'s advantage is ratings volume (34K vs 1) and device support (4 vs 2). On price, rating, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Calculator· sells 3 in-app purchases, starting at $0.99 per month and SpecScan VIN Decoder sells 3 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.9 for Calculator· against 5.0 for SpecScan VIN Decoder. That said, the two scores are not equally well evidenced: Calculator· has 34K ratings behind it against 1, so its average is the more settled of the two.
