I've been lurking and buying in this sub for a while. And I kept running into the same problems over and over. Couldn't quickly check if I already owned a pressing someone listed. Couldn't track which records on my wishlist had dropped to a price I'd actually pay. Couldn't compare pressings on the spot without opening six Discogs tabs. Had to rely on memory to know what I was missing from a discography when someone posted a [For Sale] lot.
I'm an iOS developer and a collector. So I built an app that solves all of this. It's called Spinstack, it syncs with your Discogs account, and it runs on iPhone, iPad, Mac, and Apple TV.
I know this sub is primarily for buying, selling, and trading. I'm not here to post a feature list. I want to show you specifically how this app helps with the things you do in this community every day.
Never buy a duplicate again
This happens to everyone here. Someone posts a [For Sale] list. You see a title you recognize. You think you own it but you're not sure. Or you own a different pressing and you're trying to remember which one.
Spinstack syncs your entire Discogs collection and caches it locally. Search is instant. But the faster path is the Barcode Scanner. If you're at a shop or a record fair, scan the barcode. Spinstack checks against your local collection in milliseconds and tells you if you already own it. No network needed. It works in airplane mode.
Bulk Scan lets you work through an entire stack without stopping. Point, scan, flip, repeat. At the end, you review everything at once and add what you want.
Track prices on records you actually want
Every week in this sub, someone posts a record you've been hunting. The price is either right or it isn't. Most of us keep a mental list of what we'd pay. That doesn't scale.
Price Watchdog tracks market value on every record in your collection and wishlist. Per-release sparklines show how the price has moved over time. Set a target-price alert on any wishlist item and Spinstack notifies you when the market hits your number. You stop checking. It checks for you.
Biggest movers shows which records in your collection have gained or lost the most value recently. Useful when you're deciding what to sell.
Compare pressings before you commit
Someone lists an album you want. They mention the pressing but not the catalog number. Or they list three pressings of the same album and you need to know which one matters.
Other Pressings shows every pressing of a release with marketplace prices, OG badges, format tags, and community have/want counts. You can compare the $15 reissue against the $80 original pressing and see the have/want ratio that tells you how hard each one is to find.
Know your collection cold
When you're browsing [For Sale] threads, you need to know what you own and what you're missing. Spinstack gives you that.
Full collection sync with folders, condition grades, custom fields, and sort by artist, title, year, date added, or decade. Decade sort with an era-jumping scrubber so you can land in the '70s or '90s section instantly. Artist and label discography browsing so you can see every release by an artist you collect and know which ones you're still missing.
Friends lets you browse any Discogs user's collection. Useful for checking what someone in a trade thread actually owns before you propose a swap.
What's coming in 1.4: Marketplace
This is the one that matters most for this community. Marketplace integration is coming in version 1.4. Buy and sell within Spinstack, powered by Discogs. I'm building it right now. The goal is to make listing, browsing, and purchasing feel native instead of fighting the Discogs mobile web experience.
The rest of the app (quick version)
Spinstack isn't just a buying/selling tool. It's a full collection manager. Some highlights for context:
Spin Log. Log every listening session with date, rating, mood, and tracks. Your full listening history, searchable and synced across devices.
3D Cover Flow. Swipe through your collection with depth blur and reflections.
Crate Dig. A swipeable surprise from your own shelves. Just went free in 1.3.
NFC Tags. Write tags, stick them on your sleeves, tap to view or log. Batch Tag mode for your full collection.
Last.fm Scrobbling. Automatic scrobbles from every spin. Discogs dropped Last.fm support. Spinstack has it.
Vinyl DNA. A generative mandala computed from the mathematical fingerprint of your collection.
Apple TV and Mac. Your collection on the big screen. One purchase covers every device.
Full feature list at spinstackios.app.
Pricing
$9.99 once. No subscription. 30-day free trial with everything unlocked. No credit card.
I'm one developer. iOS only. No Android, no web. If you're on iPhone and your records live on Discogs, this was built for exactly what you do.
Happy to answer questions. And if you have ideas for how the Marketplace feature should work in 1.4, I'm all ears. You're the people who'll use it most.
