| App | Category | Detected stores | Detection as of | Markdown profile |
| --- | --- | --- | --- | --- |
| Tiergain GCR Google Reviews | Shipping & Fulfillment | 1 | 2026-11-09 | https://shoplist.co/shopify-apps/tiergain-gcr-google-reviews.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.
