We build an app for RedTrack.io which is itself a paid SaaS product. The app itself is fee as the only thing it does - it helps embed our 1st party data based tracking script into Shopify theme properly. Of course it does not make any sense to add this unless you are a RedTrack.io user.
Shopify user adds app and pastes the tracking script he generated in his RedTrack.io account inside the app and thats it.
How we properly position the app so we can keep it as simple as it is and free as it is?
