The four numbers a studio reviews on Monday.

Stipple derives them from raw screen and purchase events the moment a build reports in. Nobody writes a query, and nobody waits on a dashboard sprint.

Funnels drawn from the screens you already built.

The SDK names screens and purchase events on its own, so the path from install to paid exists the moment your first build reports. Rename a step later and its history follows.

  • Screen names read from view controllers and composables
  • StoreKit 2 and Play Billing purchases matched automatically
  • Every step split by build, so a bad release shows on day one

Seven lines in AppDelegate. That is the whole install.

No event schema to agree on and no analyst in the loop. The SDK batches on the device, strips identifiers before anything leaves the phone, and waits for Wi-Fi when the queue is large.

Also ships for Kotlin, React Native, Flutter and Unity.

Studios that stopped building their own dashboards.

We shipped the SDK on a Thursday and argued about the paywall with real numbers by Monday. Our old setup took a quarter to answer that question.

Our privacy counsel read the data sheet once and signed off. That has never happened with an analytics vendor.

The build split caught a crash-driven drop in onboarding six hours after release. We pulled the build before the weekend.

Priced by monthly users, never by event.

Every plan keeps data in US data centers, includes unlimited seats, and never samples. Move up a tier when an app outgrows its plan; history stays put.
