App2Web for iOS in the US: how to start today

Distributing your app into the US? 

App2Web can boost net proceeds by 35 - 40% – and give you more control over pricing, checkout, and the entire customer relationship.

But here’s the thing: making that opportunity work takes more than adding a payment link.

You need a compliant paywall, a handoff that feels trustworthy, and a subscription lifecycle that keeps working after checkout. 

In this guide we uncover exactly what that looks like:

• the compliance rules
• how the hybrid model works
• how to build effective conversion and lifecycle systems
• which implementation path fits your app and stage.

The three key rules that keep you compliant

In April 2026, Apple removed Cal AI from the App Store because of how the app structured its App2Web flow. 

Here are the rules they broke, and how to avoid doing the same 

1. They didn’t offer IAP alongside their external payment link: External checkout adds a route, it does not replace Apple's required payment option. Non-reader apps must offer IAP alongside any external payment option.
2. Billing was unclear: Before users leave the app, show the actual price, trial terms, renewal amount, timing, and where the payment will be processed.
3. They used post-decline pressure: If someone dismisses the external offer, don’t immediately serve a second, different subscription flow. Keep the journey clear and consistent.

Our take: This case makes Apple's red lines clearer than ever.

Set up a paywall your customers actually understand

Your paywall is where the App2Web motion starts. It is also where compliance and conversion meet, so show both options clearly: the standard in-app purchase and the external web checkout.

The copy matters. Users who have always paid through Apple aren't used to being sent elsewhere. And clarity is key. At this stage, it can prevent confusion and chargebacks later down the line. 

Every app is different, so what works for a meditation app may not work for a fitness app. But here’s a few first-principles worth sticking to:

• Start with transparency
• Handle objections up top
• Convert with retention in mind
• Create an emotional connection
• Think about pricing and packaging together
• Test multimedia
• Reinforce progress

Below, Phil Carter breaks down an industry leading paywall flow:

Rolling out App2Web: five steps

The web paywall is only one part of the experience. Don’t forget: everything between the paywall and a completed web checkout matters too. 

Here's what we suggest:

1. Start with one path

Once compliance is covered, it’s tempting to open everything up at once. Resist that urge. Pick one paywall, one plan, and one route to the web. This means you get a clear signal – instead of five funnels' worth of noise.

2. Nail the handoff messaging

The biggest drop-off can happen before web checkout, when users realise they are being sent somewhere else. Explain what is happening, why it is happening, and what comes next.

3. Treat speed as a KPI

Measure every handoff: paywall tap to web landing, landing to checkout, checkout to payment, payment to success, and success back into the app. That means you can spot where the friction lies before you start changing the experience.

4. Keep Apple Pay on web – and increase conversions by 5.4%

Familiar payment methods mean customers are more comfortable with the web experience – and you gain trust, particularly for iOS users who already understand Apple Pay. 

5. Design for identity and the return to app

Connect the whole journey: a unique checkout session ID, identity bridging, universal links, and a fallback success page. Users should know what they bought, see their subscription activate, and get back into the app without guesswork.

Remember: App2Web is a hybrid motion, not a migration

Here’s the reality: For most apps, App2Web means running a second revenue channel alongside IAP, rather than leaving the App Store behind. 

Existing Apple subscribers can’t simply be moved to web billing: they need to cancel and resubscribe – and many will stay on Apple permanently.

Build your model around that. Some teams use discounts or feature benefits to encourage switching. But the goal is not to force every customer onto the web, it’s to give customers a clear choice – and build a channel that compounds over time.

Don't forget the subscription lifecycle

Apple handles much of the subscription lifecycle invisibly, so when you move payments to the web, more of that responsibility becomes yours. It's also where a lot of the opportunity sits.

Trial to paid: A failed authorization at the end of a trial doesn’t automatically mean a churned subscriber. Give customers a way to update payment details, and make sure your team are thinking about retention as a key growth metric. 

Learn how Paddle helps apps cut churn by 25-30%. 

Failed payments: On the web, you control retry timing and recovery messaging. Adapt the journey for declined cards, expired payment methods, and insufficient funds.

Cancellations: A web cancellation flow can offer a pause, downgrade, or targeted save offer before the subscription ends.

Chargebacks and tax: Clear billing communication helps prevent chargebacks. As a Merchant of Record, we also handle dispute management, tax, and compliance so you do not have to build that operational layer alone.

AI-app portfolio Codeway was running Web2App and App2Web in the US and cut more than $500,000 in failed payment revenue across its portfolio, with a 36% recovery rate on failed transactions.

The lesson is simple: conversion is only the beginning.

Start with the right support

Most App2Web implementations underperform for the same reason: teams solve one side of the problem, and leave the other unresolved. 

The paywall converts, but payment recovery is patchy. Or the billing infrastructure is solid, but the handoff loses users.

Paddle and Helium cover both sides. 

Helium helps you build and test paywalls, onboarding, pricing, offers, and conversion. As a Merchant of Record, Paddle handles checkout, subscription billing, tax, failed payment recovery, chargebacks, and cancellation intervention. 

Together, it means you obsess, while we handle the rest.

Ready to start?

Kick off with one market or one acquisition funnel, and before you expand, learn from the results.

1. Complete Paddle onboarding and set up Hosted Checkout for the US
2. Update your paywall to show both IAP and web checkout options
3. Confirm entitlement provisioning works, from payment through to the app
4. Track authorization rate, trial-to-paid conversion, and payment recovery separately from App Store metrics
5. Once conversion is stable, move to the Starter Kit for a more branded experience, then expand.
