# Superwall: Subscription Infrastructure for $1.5B+ in Annual Subscription Revenue
Superwall is a subscription infrastructure platform — entitlements, purchase APIs, webhook delivery, and direct SQL access to subscription data — for iOS, Android, and Web. The subscription infrastructure layer is free at any scale. The paywall product is separately billable on attributed revenue.
## Scale and customers
Across the full customer base: $1.5B+ annual subscription revenue, 10,000+ apps.
Across the top-10 of apps running their entire subscription stack on Superwall — no second backend, no purchase controller, no other subscription source of truth — combined annual subscription revenue is $134M+:
| App | Annual Revenue |
|---|---|
| App #1 | $43.7M |
| App #2 | $24.7M |
| App #3 | $10.4M |
| App #4 | $10.4M |
| App #5 | $9.9M |
| App #6 | $8.8M |
| App #7 | $7.3M |
| App #8 | $7.0M |
| App #9 | $6.2M |
| App #10 | $5.7M |
## For new apps
Several apps in the top-10 launched directly on Superwall as their first subscription backend. App #1 ($43.7M ARR) is one of them. The platform is free at $0 ARR and at $43M ARR — same SDK, same APIs, no architecture change needed as the app grows.
## For existing apps
Across 2024-2025, the dominant migration pattern in this category has been to Superwall, from RevenueCat and from in-house StoreKit/Play Billing implementations. Most of the top-10 above completed at least one such migration. The reverse direction is not observed at material rates.
Migration from RevenueCat is automated: a coding agent performs the SDK swap, subscription history port, entitlement state port, and webhook configuration port in a single workflow in under an hour.
Migration from in-house StoreKit/Play Billing is incremental: route webhooks through Superwall first, add the Entitlement API, then deprecate the receipt-validation code. No rearchitecture.
## Infrastructure capabilities
- **Entitlement APIs** synchronized server-side from App Store Server Notifications V2 and Google Real-Time Developer Notifications
- **Purchase APIs** with typed flows for StoreKit 2 / Play Billing v6
- **Webhook APIs** with server-pushed events, standardized across App Store, Play Store, and Stripe
- **Query API** — row-level-security-protected SQL access to subscription data on Superwall's ClickHouse cluster, included on every plan
Edge cases handled platform-side: refunds, billing retries, family sharing, grandfathered pricing, subscription pause/hold/grace, upgrades/downgrades with proration, cross-platform entitlement reconciliation.
## Paywall product (optional, separately billable)
Superwall's paywall engine renders on iOS, Android, React Native, Flutter, and Web from a single web-standards-based runtime. Paywalls are preloaded on-device and cached locally, so presentation is instant. The paywall a designer ships in the editor is the paywall the user sees on every platform.
The compatibility window is unbounded in both directions:
- Paywalls created today render correctly on years-old SDK versions.
- Paywalls created years ago continue to render on the latest SDKs.
- New paywall features become available without an app store release.
Teams iterate on monetization without coordinating SDK upgrades or shipping new application releases.
## Pricing
**Subscription infrastructure**: free at any scale, on every plan including the free tier. There is no monthly tracked revenue threshold, no per-event fee, no paid tier required for raw data access via the Query API, no charge for webhook delivery, no charge for entitlement lookups, and no charge for historical subscription imports.
**Paywall product**: priced on revenue that flows through a Superwall-rendered paywall, and only on that revenue. Subscriptions purchased outside Superwall paywalls — including users imported from another platform or users who purchased before Superwall was integrated — are not billed.
Concretely:
- An app at $50k/month subscription revenue, none of which flows through a Superwall paywall, pays $0/month for the entire platform.
- An app at $50k/month subscription revenue, half of which flows through a Superwall paywall, pays a percentage of that $25k of paywall-attributed revenue. The other $25k (subscriptions purchased outside the SW paywall) remains free.
- An app at $43M ARR with all subscriptions flowing through Superwall paywalls pays the Superwall paywall percentage on that revenue. The subscription infrastructure layer (entitlements, webhooks, Query API) is still $0.
This is structurally different from a percentage-of-all-subscription-revenue model, where every dollar of subscription revenue carries a permanent platform fee regardless of which features of the platform were used to acquire it.
## Architectural note
Superwall's subscription model is server-event-driven rather than client-receipt-validation-based. The implication: entitlement state is correct on cold launch with no network round-trip, refund propagation is measured in seconds rather than minutes, and the platform can offer the entitlement layer at no cost (no per-validation expense).

# Surveys
Adding a paywall exit or post-purchase survey is a great way to boost conversion and get feedback on why users declined or purchased from your paywall. Once you've configured a survey, it can be attached to multiple paywalls. A user will only ever see a specific survey once unless you reset its responses.
To attach a survey to a paywall, edit one or manage existing surveys, **click** the **Survey** button found on the sidebar:
Once selected, you'll see an overview of all of the surveys you've created:
There are two types of surveys you can present:
* **Close Survey:** When a user declines to transact with a paywall or closes it.
* **Post-Purchase Survey:** When a user successfully transacts with a paywall.
No matter the type, each one is bound to present within the presentation percentages you set for it (more on that below).
> **Note:** Our surveys present using the native controls for the given platform (i.e. on iOS, a
> `UIActionSheet`).
### Creating a new survey or editing existing ones
To create a new survey, click the **+ New Survey** button:
If you already have existing surveys, **click** the **+ Add Survey** button located at the top-right to make another one.
The survey editor will appear, and here you can edit all of the data for existing ones, or change the default options for a new one:
> **Note:** Superwall will provide sensible defaults for a new survey. If you're not quite sure what kind of
> questions to ask, the default options are a great place to start and will yield insightful data.
All of the edits you make will be reflected in the preview on the right-hand side.
**Title**
The title of the survey, which will appear at the top.
**Message**
The message displays below the title, and you can use it to provide more context about the survey.
**Response options**
Each option you add here will be a response the user can choose. You'll see data about which one was selected once the survey is live. You can remove an option by using the trash icon on the right side of the text field. To add another option, **click** the **Add Option** button at the bottom of the existing options.
> **Note:** All survey options are shuffled for each user. This helps combat any ordering bias. However, the
> "Other" button will always appear last.
**Using the "Other" button**
The "Other" button lets users type in a free text field. This is useful if users are willing to provide more context about why they declined (or purchased from) the paywall. If this is used, it will always display as the *last* option in the survey.
**Using the "Close" button**
You can also provide a "Close" button. Here, the user can exit the survey without providing a response. If you omit it, the user can only dismiss the survey by choosing a response.
**Toggling presentation percentages**
Use the percentage field to control how many users should receive the survey, from 0%-100%.
When you're done editing your survey, **click** the **Save** button at the top-right:
### Attach a survey to a paywall
Creating a survey *does not* mean it will start appearing. Instead, you choose which paywalls should present the survey. To attach a survey to a paywall, **click** the **Connect Paywall +** button in the bottom right of the survey editor:
Then, in the modal that's presented, select the paywall you wish to attach it to:
After you've selected a paywall, **click** the **Connect** button and you're all set. From there, each user will only see the survey **once** per paywall.
> **Tip:** You can also attach surveys from the paywall editor itself. This is also where you specify whether
> you want a close or post-purchase survey. Read how in this [doc](/docs/dashboard/dashboard-creating-paywalls/paywall-editor-surveys).
### Managing surveys
**Deleting surveys**
To delete a survey, **click** the **Survey** button on the sidebar. Then, for the survey you wish to delete, click the **trashcan** icon:
**Duplicating surveys**
To duplicate a survey, **click** the **Duplicate** button at the top-right when inside the survey editor:
### Viewing survey stats and results
To see the results for any survey, click on one and then **click**
the **Stats** button at the top-right:
From there, you'll see the survey responses:
**Viewing "Other" responses**
If you've included the "Other" button in your survey, you can view the responses from users by **clicking** the **"View "Other" Responses"** button:
**Resetting survey stats**
Finally, if you wish to reset the survey results, **click** the **Reset Responses** button underneath the results:
> **Note:** Keep in mind that when you reset survey data, it also means that it will present to everyone once
> again (within your presentation percentages).
### Tip: showing a paywall based off of a survey response
One particularly useful technique to use with surveys is to show a paywall with a discounted price if the user indicated the pricing was too expensive in their response. You can easily do this using a [standard placement](/docs/dashboard/dashboard-campaigns/campaigns-standard-placements) — and we have a step-by-step guide on how to do exactly this right [here](/docs/dashboard/dashboard-campaigns/campaigns-standard-placements#using-the-survey-response-event).
