Puckive

A private, local-first iOS app for audiophiles and music collectors. Catalog every pressing in your vinyl and CD collection with complete data sovereignty.

Where the name comes from

The idea behind Puckive

Development is underway — here's an early look at the actual sign-in screen, styled after the walnut, brushed steel, and brass of the precision turntable stabilizer weight that gave the app its name.

No compromises on privacy, speed, or pressing accuracy

🛡️

Data Sovereignty

All data persists locally in SwiftData and syncs securely via your private iCloud container (CloudKit). Zero third-party trackers, servers, or analytics.

👁️

Cover OCR Scanning

Leverages Apple's native Vision framework to scan barcodes and sleeve text, automatically building rich search terms for instant lookup.

⏱️

MusicBrainz Lookup

Enrich details from global databases with a built-in rate-limiting system that prevents IP blocking, maintaining high retrieval success rates.

💿

Pressing Variant Analytics

A specialized duplicate detector that groups identical matches while calling out distinct regional pressings, remasters, or formats.

Built for Big Collections

A dedicated dual-image pipeline downsamples covers to lightweight thumbnails, keeping scrolling fast and memory light even at 1,000+ records.

📂

Backup & Export

Export your entire library as a clean tab-separated (.tsv) sheet using iOS document pickers or native share sheets.
