At least so far, it pulls your collection from discogs and lets you flip through it as if you're thumbing through the bins. But it only pulled about a third of my collection. It's a nice visualization to see what you've got that is better than discogs which is so clunky if you have a big collection.
I assume this is an app and not something that is web based? Which is a deal breaker for me. I use my phone, but not when I'm spinning records because I'm right near my PC.
Become a Patron for life for $100. Or get exclusive things for $5 a month. Or be basic with free which gives 1 Discogs sync per week. Or pay for automated sync.
Got my collection loaded up to it. I flipped some record art. I think some website can use the Discogs API to make a better Discogs, but I also like having those minutiae details like runouts. This and others try to simplify it a bit too much. At the very least let me sort by album title, so I can see my scores/soundtracks by movie title rather than a composer I don't know off the top of my head.
