At the record store wondering "Do I already own this?" Digging through crates at the record convention and feeling paranoid about opening up Discogs on your phone? VinylCheck instantly helps you search your collection to see if you own something, and which version it is. Scan a barcode or search by artist and album to check your Discogs collection and wantlist in seconds. Avoid the awkward gaze of record store owners who don’t like customers using Discogs while shopping (it happens). SCAN BARCODES 
Point your camera at any record's barcode for instant lookup. Works with UPC and EAN codes. CHECK YOUR COLLECTION 
See immediately whether you own it, want it, or haven't logged it. Color-coded badges make status clear at a glance. SEE PRICING 
View Discogs marketplace pricing — low, median, and high — to know if you're getting a fair deal. SEARCH MANUALLY 
No barcode? Search by artist or album title. Results group different pressings so you can find the exact version. MANAGE YOUR WANTLIST 
Add or remove records from your Discogs wantlist directly from search results. WORKS OFFLINE 
Your collection syncs locally, so you can check ownership even without signal in a basement record shop. This app requires a free Discogs account.
