Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureThis app connects your CircaOS system to your Shopify store. When you process second-hand or consignment items in CircaOS, you can push product listings — including photos, metadata, SKUs, and descriptions — directly to Shopify. The app gives you control over which items publish online, so your storefront stays accurate without manual data entry.
Independent record stores often have limited online discovery, and collectors usually cannot tell what a store stocks without visiting in person. Spindig is not a marketplace but a discovery app where collectors search for nearby record stores and specific titles.
- Push inventory listings from CircaOS to Shopify in one click.
- Sync product photos, metadata and descriptions automatically.
- Seamlessly capture product data for effortless resale inventory management.
- Your Shopify product catalog appears on Spindig and stays up to date
