Everything your web‑to‑app funnel needs, out of the box. Sessions, payments, routing, attribution, analytics, and experiments -so you can focus on the UI while we handle the backend.

Sessions

Automatic session management with cross-device restoration. Anonymous users become identified customers seamlessly.

Payments

Stripe and Paddle out of the box. Subscriptions, trials, one-time purchases, upsells, and order bumps -all handled.

Routing

Conditional page flows based on quiz answers, variables, and custom logic. Build skip logic without writing code.

100% Attribution

Deterministic tracking from ad click to purchase. Server-side Meta CAPI with automatic hashing. No ATT prompts.

Analytics

Real-time dashboards with conversion funnels, ARPU, cohort analysis, and drop-off tracking across every step.

Experiments

A/B test entire funnels or individual pages with automatic traffic splitting and statistical confidence.

A reliable web2app backend takes weeks. Even with AI coding. And building is just 20% of the work -the rest is maintaining it, debugging edge cases, and keeping up with every API change.

Then you maintain it. Forever.

Stripe changes their webhook format -your payments break. Meta updates CAPI requirements -your attribution goes dark. Analytics queries slow down at scale -your dashboards time out. Every hour spent firefighting infrastructure is an hour not spent on what actually makes you money.

From ad click to paying subscriber. AppFunnel sits between your ads and your app, converting traffic into revenue on the web before users ever download.

1. Ad Click

User clicks your ad on Meta, TikTok, or Google.

2. Web Funnel

They land on a personalized onboarding flow.

AppFunnel

3. Web Paywall

They subscribe via Stripe or Paddle. No 30% App Store fee.

AppFunnel

4. Download App

They download your app, already subscribed.

Why not just use in‑app paywalls? RevenueCat and Superwall are great for in‑app monetization. Web funnels solve a different problem - they let you convert users before the download.

In-app paywalls

The problem: Requiring a download before showing value creates friction. Many users drop off before ever seeing your offer.

The advantage: Qualify and convert users before the download. They arrive in your app already committed.

Billing Issues

fewer chargebacks & failed payments

The problem

They were spending over 30% of revenue on App Store fees with zero visibility into which ad campaigns drove paying users. Attribution was broken post-ATT, and trial-to-paid conversion sat well below industry average.

The solution

They moved their paywall to the web with AppFunnel, capturing payments via Stripe before users ever hit the App Store. A personalized quiz funnel pre-qualified users, and server-side attribution gave them full visibility into every dollar spent on ads.

“AppFunnel showed us exactly where users were dropping off in our onboarding. We restructured three screens based on the data and saw trial starts jump 47% in the first week.”

Web‑to‑app funnel FAQ

Users subscribe on the web via Stripe or Paddle before downloading your app. Since the transaction happens outside the App Store, Apple's 30% commission doesn't apply. Users then download your app and are already subscribed -no in-app purchase needed.

No. Apple allows apps that don't offer in-app purchases -the subscription simply isn't initiated inside the app. Many major apps (Spotify, Netflix, etc.) use this exact model. Your app recognizes the user's existing subscription via your backend.

We integrate with Stripe and Paddle out of the box. Both support subscriptions, free trials, and one-time payments. You can use your existing Stripe account -we just handle the funnel and checkout flow on top of it.

Since the entire conversion happens on the web (ad click → quiz → payment), you get deterministic, first-party attribution data. No IDFA needed. We fire server-side events (Meta CAPI, Google Ads, TikTok) so you know exactly which campaign drove each paying subscriber.

Yes. Every funnel runs on your custom domain with automatic SSL. Users see your brand throughout the entire experience -from ad click to payment confirmation.

Most teams have their first funnel live within a day. If you're using the headless SDK, your AI coding agent can scaffold the entire UI from your existing in-app onboarding -AppFunnel handles all the backend complexity.

Yes. You can test different quiz flows, paywall designs, pricing, and trial lengths. Split traffic by percentage and measure by revenue, not just clicks. Results are available in real-time in the analytics dashboard.

A web-to-app funnel (also called web2app) is a web-based onboarding and payment flow that sits between your ads and your mobile app. Users click an ad, land on a personalized quiz or onboarding experience on the web, subscribe via Stripe or Paddle, and then download your app already paid. This lets you bypass the 30% App Store fee and get deterministic attribution on every conversion.

They use web2app funnels. Instead of monetizing inside the app (where Apple takes 15–30%), they run ads that send users to a web-based quiz and paywall. The user subscribes on the web via Stripe, then downloads the app already logged in and paid. Apple allows this because the purchase happens outside the app. AppFunnel gives every team this same infrastructure.

FunnelFox and Web2wave are no-code-only funnel builders. AppFunnel is fundamentally different: it’s headless infrastructure. You get a full React SDK so your team (or an AI coding agent like Claude) owns the UI completely — no template constraints. AppFunnel handles the backend: sessions, payments, routing, attribution, and experiments. If you need pixel-perfect control or want AI agents to build your funnels, AppFunnel is the right fit.

Yes. The headless SDK is built for React. You get typed hooks for navigation, responses, payments, and user data. You can also use the no-code visual editor if you prefer not to write code — both approaches use the same backend infrastructure.

Yes. You connect your own Stripe account and AppFunnel handles the checkout flow, subscription lifecycle, webhooks, and retry logic on top of it. Revenue goes directly to your Stripe account — we never touch your funds.

Stop giving 30% to the App Store. Start capturing revenue on the web.
