From one changeto the first conversation.

A real account, start to finish: what Shoplist showed when Liquida Sport removed Smile, and what you do next.

  1. Catch the change.

    Sonar stopped seeing Smile on Liquida Sport on Oct 22, 3 months after it first appeared. If you sell a loyalty app, that is the week to call.

  2. See what’s left.

    12 apps still run there, 404/301 SC Easy URL Redirects and Affirm pay‑over‑time messaging among them. No loyalty and subscriptions app is detected. That’s the shape of the opening, and of your pitch.

  3. Save it. Hear when it moves.

    Add the brand to a list with the reason attached, follow it, and get a Slack or email alert the next time its stack changes. Export the list when you’re ready to reach out.

If Shoplist shows an app on a store,it’s there.

Sonar, Shoplist’s crawler, reads Shopify storefronts and records the apps actually running on them. A detection is an observed install, not a probability, and every brand page shows when it was last checked.
