The Performance tab is app-growth analytics: revenue (or MRR), downloads, store impressions, product-page views, conversion rate, active subscribers, churn, and ARPU: with a comparison chart, unit-economics strip, and per-channel breakdown.
The conversion funnel runs Impressions → Page views → Downloads → Free trials → Paying, each stage fed by a real source (App Store Connect for store metrics, your subscription platform for trials and revenue).
One rule everywhere: the tab never fabricates a number. A metric with no connected source shows a Connect button instead of a made-up value, and unconnected funnel stages are excluded from conversion math.
Content metrics (views, posts, engagement) live with your campaigns: Performance is about what that attention converts into.
