# 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.

# Understanding Experiment Results

To view the results of any paywall experiment that's running, **click** the **Results** tab in the campaign details view:

![](https://2a2314a4-superwall-docs.staffbar.workers.dev/docs/images/campaigns-exp-results.jpeg)

There are three main sections: **Paywalls**, **Placements**, and &#x2A;*Graphs (defaults to Proceeds Per User)**. Each section has a toggle at the top right to change associated metrics.

### Paywalls

Here, you'll see each paywall being used (or that was used) in an experiment. Superwall will show you metrics such as proceeds, users and much more. There are several metric to explore, and you can hover over any of them to get more details about what each metric represents:

![](https://2a2314a4-superwall-docs.staffbar.workers.dev/docs/images/campaigns-exp-hover.png)

> **Note:** Subscription lifecycle events (i.e. renewals, cancellations, etc) are matched to paywall
> conversions using unique identifiers provided by the platform at checkout and via webhook events.

You can also filter results per paywall. Click the checkbox next to one to have the results page only show data for that specific paywall:

### Placements

Here, you can get a detailed breakdown of each placement associated with the campaign. This helps you form a clear picture of what features or actions are leading to conversions.

### Graphs

Finally, the last section has several graphs to explore campaign performance. It defaults to Proceeds Per User.

### Setting up revenue tracking

Before any metrics based on revenue will display, you need to set up revenue tracking. To set up revenue tracking:

1. **Click** on **Settings** in the dashboard.
2. **Click** on **Revenue Tracking**.
3. Use the guides to follow any of the revenue tracking methods. For more details, check out our [docs](/docs/dashboard/dashboard-settings/overview-settings-revenue-tracking).

![](https://2a2314a4-superwall-docs.staffbar.workers.dev/docs/images/campaign-exp-rev-tracking.png)

If you don't have revenue tracking setup, you will see a banner on your dashboard:

### A note on conversions, trial starts, and subscription starts

Each experiment will notably report **conversions**, **trials starts** and **subscription starts**. In some cases, it may seem like these numbers don't match up quite how you'd expect. That could be due to a few different reasons:

1. **Reporting methods:** Conversions are an *SDK reported* event, while trial and subscription starts are *server reported* events. Sometimes, the server events might be a little behind on their reporting — whereas SDK events are usually instantaneous.
2. **Understanding Resubscriptions and Cancellations:** When someone resubscribes or restarts a paused subscription through a paywall, it *won't* be considered a new trial or a new subscription start. However, it *will* be counted as a **conversion**. As such, any revenue generated will be linked to that paywall. If they later decide to cancel the subscription, the cancellation will also be linked to the same paywall.
3. **Attribution:** And finally, attribution can sometimes be a complicated metric to track. If something doesn't look right on your end, please feel free to reach out to us and we'll always export your data so you can exactly where our numbers are coming from.

### Confidence intervals

Use confidence intervals to gauge how each paywall is performing against the other ones in your experiments. Hover over a specific metric to view the confience interval (i.e. Conversion Rate, Proceeds Per User, etc.):

![](https://2a2314a4-superwall-docs.staffbar.workers.dev/docs/images/campaign-exp-interval.png)

Keep in mind that these intervals represent the percentage of users converted, it doesn't take into account revenue. Put differently, paywall A could have a higher conversion rate, but with a much cheaper offering than paywall B. Paywall B could still be making more money, but at a lower conversion rate with the higher-priced product.

### Identifiers and cohorting with 3rd party analytics

If you scroll to the end of the experiment results table, you'll find some useful identifiers which you can use to interface with third-party tools you may be using:

![](https://2a2314a4-superwall-docs.staffbar.workers.dev/docs/images/campaign-exp-cohorting.png)

1. **Experiment id:** The identifier of the experiment that the paywall is a part of.
2. **Variant id:** The identifier representing the variant the paywall represented in the experiment.
3. **Paywall id:** The identifier for the paywall in the experiment, which associates back to the variant.
