Your shelf · at a glance
Every cover. Every pressing. One private library.
Browse the whole collection, then open the exact pressing without losing the warmth of the artwork.
How it works
Three moves, and your shelf lives in your pocket.
No spreadsheet, no data entry marathon. Add a record, make it yours, and never forget what to spin.
1
Add in seconds
Scan a barcode, paste a Discogs or eBay link, import your whole Discogs collection — or just hear a record playing and let Krat13 recognise it.
2
Make it yours
Browse in Grid, Vinyl, List, or a full-bleed Wall of every cover. Smart filters, custom tags, and your own drag-to-sort order.
3
Rediscover what to spin
Log a play with one tap. A daily “Today’s Spin” pulls a forgotten record back off the shelf and into your hands.
Signature features
Two things that make Krat13 different.
Free
Tap the sleeve. Log the play.
Stick an NFC tag on a sleeve once. From then on, tap it with your iPhone and Krat13 opens Quick Log for that exact copy — confirm, and the play is logged. No searching, no typing.
Free
Listen & Identify
Hear something you love at a friend’s place or in a shop? Tap Listen — Krat13 recognises the song, finds the album, and lets you review a vinyl release before adding it to your Want List.
Everything on one shelf
A real collection tool, not a note in your phone.
Add any way
Barcode, cover, a store link, Discogs, CSV, or by hand — whatever’s fastest for the record in front of you.
Grid · Vinyl · List · Wall
Four ways to browse, from practical Grid and List to tactile Vinyl and a full-bleed, shareable Wall.
Play history & Now Spinning
Log plays, get a daily forgotten-record pick, and share a polished Now Spinning card.
Smart filters & tags
Find what’s missing — cover, condition, price, value, shelf — plus custom tags like “gift from Mom” or “shop finds.”
Want List & Hunt Board
List, Grid, or a decision-focused Hunt Board — with priorities, target prices, owned warnings, and sharing.
Quick Log
Log a play from Control Center, the Action Button, Siri, or an NFC-tagged sleeve — without opening your Collection first.
Siri & Shortcuts
“Log Blue in Krat13.” “Pick a record in Krat13.” Krat13 answers, hands-free.
Widgets & Live Activity
Today’s Spin, Recently Added, and Vinyl Shelf widgets for Home, Lock Screen, and StandBy — plus Now Spinning in the Dynamic Island.
Stats & achievements
See what you play, where your collection is growing, and the milestones you’ve reached across genres, decades, and shelves.
Market value & Discogs sync
Per-record value from Discogs, and two-way Collection and Want List sync — free, powered by your Discogs account.
Inside Krat13
The app, from shelf to share.
The collection stays visual. The details stay close. Nothing gets between you and the next record.
Today’s Spin
A reason to pull one more record.
Krat13 brings a forgotten sleeve forward, keeps your listening history one tap away, and turns a spin into a card worth sharing.
At the record shop
Know the hunt before you walk in.
Priorities, target prices, and owned-record warnings keep the want list useful in the aisle.

Krat13 Pro
Go deeper with Pro.
The whole catalogue is free — no record-count cap, and that includes Discogs import, two-way sync, and market value. Pro adds the tools Krat13 builds on top: smarter organisation, deeper insight, personalised widgets, and PDF catalog export run on your device; Premium Cover Scan uses Krat13’s disclosed vision backend.
Premium cover scan
Photograph both sides and let Krat13’s visual recognition rank likely pressings for you to confirm.
Smart Collections
Dynamic views that organise your library automatically — Never Played, Rediscover, By Decade — and stay current as it grows.
Collection Insights
See what needs attention — forgotten records, missing details, and duplicate editions — each a tap from the records.
Deep analytics
Go beyond the basic stats: spending, listening, and how your collection breaks down and grows over time.
Advanced Widgets
A Home Screen widget you tune to your collection and listening habits — rediscover a record, longest unplayed, and more.
PDF catalog
A polished, formatted report of your whole collection — for archiving, insurance, or resale.
A monthly or yearly subscription; the current price is shown in the App Store before you buy. See the Terms for details.
