# 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.

# Install the SDK

Install the Superwall React Native SDK via your favorite package manager.

This guide is for Expo projects that want to integrate Superwall using our Expo SDK.

> **Note:** **This doesn't sound like you?**- **React Native app, new to Superwall** → See our [installation guide for bare React Native apps](/docs/expo/guides/using-expo-sdk-in-bare-react-native)
> - **React Native app with existing Superwall SDK** → See our [migration guide](/docs/expo/guides/migrating-react-native)

> **Warning:** **Important: Expo SDK 53+ Required**This SDK is exclusively compatible with Expo SDK version 53 and newer. For projects using older Expo versions, please use our [legacy React Native SDK](https://github.com/superwall/react-native-superwall).

> **Warning:** **Expo Go is Not Supported**The Superwall SDK uses native modules that are not available in Expo Go. You must use an [Expo Development Build](https://docs.expo.dev/develop/development-builds/introduction/) to run your app with Superwall.To create a development build:```bash
> npx expo run:ios
> # or
> npx expo run:android
> ```If you see the error `Cannot find native module 'SuperwallExpo'`, see our [Debugging guide](/docs/expo/guides/debugging) for solutions.

To see the latest release, check out the [Superwall Expo SDK repo](https://github.com/superwall/expo-superwall).

## Version Targeting

> **Warning:** Superwall requires iOS 15.1 or higher, as well as Android SDK 21 or higher. Your iOS deployment target must also meet the minimum required by your installed Expo SDK. For Expo SDK 56 and newer, use iOS 16.4 or higher.

First, install the `expo-build-properties` config plugin if your Expo project hasn’t yet:

```bash
npx expo install expo-build-properties
```

Then, add the following to your `app.json` or `app.config.js` file:

```json
{
  "expo": {
    "plugins": [
      ...
      [
        "expo-build-properties",
        {
          "android": {
            "minSdkVersion": 21
          },
          "ios": {
              "deploymentTarget": "15.1" // Use 16.4 or higher for Expo SDK 56+
          }
        }
      ]
    ]
  }
}
```
