# 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.

# watchOS and tvOS Support

Track purchases, subscription status and entitlements on Apple Watch and Apple TV with SuperwallKit, and handle placements without paywall presentation.

SuperwallKit supports watchOS and tvOS apps that need purchases, subscription status, entitlements, user attributes and events. Neither platform can show Superwall paywalls. Use your own purchase UI and the same configuration and identity APIs as on iOS.

## Requirements

* SuperwallKit 4.19.1 or later, installed through Swift Package Manager. CocoaPods does not support these platforms.
* watchOS 8 or later, or tvOS 15 or later, and Xcode 26 (Swift 6.2) or later.
* App Store products and signing configured for the app when using StoreKit purchases.

## Set Up the SDK

[Install SuperwallKit with Swift Package Manager](/docs/ios/quickstart/install#install-via-swift-package-manager), selecting version 4.19.1 or later and adding it to your watchOS or tvOS app target. Configure it at launch. To observe purchases made through your own purchase flow:

```swift
import SuperwallKit

let options = SuperwallOptions()
options.shouldObservePurchases = true
Superwall.configure(apiKey: "YOUR_PUBLIC_API_KEY", options: options)
```

You can identify users, set attributes, track placements, purchase and restore, use observer mode, read subscription status, entitlements and `CustomerInfo`, redeem web checkout purchases, and use `SuperwallDelegate` as on iOS. See [Direct Purchasing](/docs/ios/guides/direct-purchasing) and [Observer Mode](/docs/ios/guides/advanced/observer-mode).

## Placements Without Paywalls

`register(placement:)` still evaluates campaign audience filters:

* A holdout or a placement with no matching audience is skipped and runs the feature block.
* If a paywall matches and can be fetched, a non-gated paywall runs the feature. A gated paywall does not run the feature and calls the handler's `onError` instead.
* If the matched paywall cannot be fetched, `onError` receives that error and the feature does not run.
* `onPresent` and `onDismiss` are not called because nothing is shown.

Use [`PaywallPresentationHandler`](/docs/ios/sdk-reference/PaywallPresentationHandler) to handle skips and errors. [`getPresentationResult(forPlacement:)`](/docs/ios/sdk-reference/getPresentationResult) reports which paywall the user would see without loading its UI. Implicit placements such as `app_launch` do not trigger paywalls on these platforms.

## Limitations

* Paywalls, the debugger, Test Mode and Customer Center are unavailable. `getPaywall`, `PaywallView` and other APIs that require paywall UI are not available.
* Paywall preloading does nothing. `latestPaywallInfo` is always `nil`, and `isPaywallPresented` is always `false`.
* MMP install matching and Apple Search Ads attribution do not run on either platform.
* tvOS does not schedule local notifications such as free-trial reminders.
* watchOS reports connection type as `Unknown` and device interface type as `watch`.
