## Public app portfolio sample
| App | Category | Detected stores | Detection as of | Markdown profile |
| --- | --- | --- | --- | --- |
| QX ‑ Quantity Discount Price | Discounts | 146 | 2026-10-24 | https://shoplist.co/shopify-apps/quantity-x-quantity-breaks.md |
| MBC Bundle Builder BYOB | Product bundles | 68 | 2026-10-24 | https://shoplist.co/shopify-apps/mbc-bundle-builder.md |

This profile displays 2 apps, bounded to twelve. Detection counts describe storefront evidence per app, not unique customers across the portfolio. A store using several apps is counted once for each app; adding these counts does not produce a unique store total. Missing counts or dates mean unavailable evidence.
