Usually one. Supermetrics if you are feeding your own stack. Polar if you want managed Shopify dashboards.

Does The Ad Spend replace them?

No. They centralize data. The Ad Spend records and explains ad-account changes and acts on approval. If that is the actual need, it is the better buy.

Infrastructure teams pick Supermetrics. Lean DTC teams who do not want to build BI pick Polar.

Is there an alternative when you need the interpretation?

The Ad Spend, in the web app and Slack, with the timeline underneath and no BI stack required.
