For collectors who care about the details

Know exactly which pressing you own. And whether it's worth keeping.

Point your camera at a barcode, an OBI strip or a catalog number. OBI Scanner finds the exact release on Discogs, shows what it sells for and ranks it against every other known edition, from Japanese SHM-CDs to audiophile SACD reissues.

Collection of 98 discs with an estimated value of 2,935 US$
The walkthrough

Not another barcode app.

A generic scanner tells you the album. OBI Scanner tells you which of its twenty pressings is sitting on your shelf.

Scan

Barcode, OBI strip or catalog number.

Take a photo of the disc and on-device Vision reads the barcode and every catalog number it can find, including the tiny print on Japanese OBI strips. Scan a whole shelf in batch mode, open an image from Files, or search by hand when the disc isn't in front of you.

Identify

The exact release, not just the album.

Label, catalog number, country, year and format, straight from Discogs. Swipe through the Discogs photos next to your own to confirm it's the same pressing, then see the lowest price, copies for sale and how many collectors want it.

How it works

Read the obi. Find the pressing. Rank it.

An OBI strip is full of text that isn't a catalog number: format logos, prices, disc counts. OBI Scanner reads all of it, works out which code is the real one and only accepts Discogs matches whose catalog number actually agrees.

  • 01 READ On-device text and barcode recognition. EAN-13, UPC and catalog numbers in any orientation, straight from the camera or a photo.
  • 02 MATCH Barcode first, then catalog numbers ranked by how much they look like a real label code. Fuzzy lookalikes from other labels are thrown out.
  • 03 RANK Every known version of the album scored out of 100 on format, dynamic range, mastering engineer, country, era and collector demand.

A real scan. The obi's format text reads like a catalog number, and a naive search would return a Mike Oldfield compilation.

What's inside

Made for the shelf, not the playlist.

Built for collectors who know the difference between a 1985 Denon pressing and the 2011 remaster, and want their phone to know it too.

  • Built for OBI strips

    Japanese label codes like POCS, UICY, SICP and WPCR are recognised and searched first. SHM-CD, Blu-spec, SACD, mini-LP sleeves, K2 remasters: all fair game.

  • Every version ranked

    See all known pressings of an album side by side, scored out of 100, with yours highlighted. Find out whether you own the one to keep or the one to replace.

  • Dynamic range data

    DR values from the Loudness War database for each version, so the brickwalled remaster stops hiding behind nice packaging. Measured it yourself? Enter your own.

  • Market value

    Lowest Discogs Marketplace price, copies for sale and how many collectors want it, for the exact edition, plus the estimated value of your whole collection.

  • Forum consensus

    Optionally pulls in what the Steve Hoffman Forums say about each mastering and which engineers they recommend.

  • Batch scanning

    Working through a shelf? Batch mode scans disc after disc and saves unique matches automatically, only stopping when it needs you to pick.

  • Private by design

    Text recognition runs on your device. No account, no analytics, no ads. Your collection lives on your device and in your own iCloud.

  • iPhone, iPad and Mac

    One purchase, every device. Your collection syncs through iCloud, and the Mac version works with your webcam or with images from Finder.

  • Play it on MPD

    Run a Music Player Daemon at home? OBI Scanner can show a play button on releases that are already in your library.
