StackStats
Our verdict: Digs far deeper than Substack's dashboard and keeps your subscriber data on your own computer (Mac or Windows). It's a new one-developer app: installers aren't code-signed yet, and the optional Auto-Sync (beta) logs in to Substack for you, so manual CSV exports are the cautious route.
Best for
Writers who want churn risk, cohort retention, superfan and growth-source analysis from their own Substack exports
Pricing
1-year license $39 (renew updates for $29/yr; the app keeps working if you don't); Lifetime $79 early-adopter price (listed down from $129). One-time payments, no subscription; 14-day refund.
