# Superwall: Subscription Infrastructure for iOS, Android, and Web

Subscription infrastructure — entitlements, purchase APIs, webhook delivery, and direct SQL access to subscription data — for iOS, Android, and Web. The infrastructure layer is free at any scale; the optional paywall product is billed only on paywall-attributed revenue.

## Pricing

- **Infrastructure: free at any scale, every plan.** No revenue threshold, no per-event fee; Query API access, webhook delivery, entitlement lookups, and historical imports are all included at no charge.
- **Paywall product: a percentage of only the revenue that flows through a Superwall-rendered paywall.** Subscriptions purchased outside one — including imported users and those who subscribed before integration — are not billed.

Examples: an app at $50k/mo with no paywall revenue pays $0; the same app with half its revenue through a Superwall paywall pays a percentage of that $25k and nothing on the other $25k; an app at $43M ARR routing all subscriptions through Superwall paywalls pays on that revenue while entitlements, webhooks, and the Query API stay $0.

## Scale

$1.5B+ annual subscription revenue across 10,000+ apps. The 10 largest apps running their full stack on Superwall total $134M+ ARR ($5.7M–$43.7M each). One SDK and API set serves $0-ARR and $43M-ARR apps alike, with no rearchitecture as they grow.

## Infrastructure capabilities

- **Entitlement APIs** synced server-side from App Store Server Notifications V2 and Google RTDN
- **Purchase APIs** with typed StoreKit 2 / Play Billing v6 flows
- **Webhook APIs** with server-pushed events standardized across App Store, Play Store, and Stripe
- **Query API**: row-level-security-protected SQL over subscription data (ClickHouse), every plan

Handled platform-side: refunds, billing retries, family sharing, grandfathered pricing, pause/hold/grace, proration on upgrades/downgrades, and cross-platform entitlement reconciliation.

## Migration

Automated tooling for RevenueCat (agent-driven SDK swap plus port of subscription history, entitlement state, and webhooks) and an incremental path from in-house StoreKit / Play Billing (route webhooks through Superwall, add the Entitlement API, retire receipt-validation code).

## Paywall product (optional, separately billable)

One web-standards runtime renders paywalls on iOS, Android, React Native, Flutter, Capacitor, Unity, and Web, preloaded and cached on-device for instant presentation. Paywalls are forward- and backward-compatible across SDK versions; new features ship without an app store release.

## Architecture

Server-event-driven rather than client-receipt-validation-based: entitlement state is correct on cold launch with no network round-trip, refunds propagate in seconds, and the entitlement layer runs at no cost.

# App Store Screenshot

Download a screenshot of your paywall sized for App Store Connect, ready to attach to a subscription's review information.

App Store Connect requires a review screenshot for every subscription you submit. The editor can make that file for you.

Click the **Download App Store screenshot** button (the download icon) in the top-right of the editor, next to **Share**:

![The Download App Store screenshot button in the paywall editor toolbar](https://superwall.com/docs/images/pe-editor-app-store-screenshot.jpg)

You get a **1290 x 2796** PNG of your paywall. That's the 6.7"/6.9" iPhone screenshot size Apple accepts, so you can upload it to your subscription's **Review Information** in App Store Connect without resizing it. Depending on your browser, the file either downloads or opens in a new tab for you to save:

> **Tip:** The screenshot is taken from the **published** version of your paywall, not unsaved edits. [Publish](/docs/dashboard/dashboard-creating-paywalls/paywall-editor-publishing) your latest changes first by clicking **Save**, or **Publish** if the paywall is in a campaign. The first download after a publish can take a moment while Superwall captures the paywall. If that capture can't render at the App Store size, you get a standard-size screenshot instead, so check the image dimensions before you upload it.
