Manage Subscriptions Across iOS & Web for Base44

    Quick answer

    Base44 apps can ship to the Apple App Store with real Cross-Platform Subscriptions — Wanilla wraps the existing Base44 web app in a native iOS shell and wires up the native framework, so nothing has to be rebuilt in Swift.

    • Apple rejects thin web wrappers under Guideline 4.2 — native Cross-Platform Subscriptions is what clears review.
    • Most apps are submitted to Apple within 24 hours of kickoff; review typically takes another 24–48 hours.
    • Digital subscriptions must run through Apple in-app purchase (StoreKit 2), not web-only Stripe billing.

    The Limits of Base44 for Mobile Monetization

    If your Base44 app is available on web and iOS, managing subscriptions across platforms is complex. Users expect to subscribe once and access everywhere, but Apple and Stripe have different billing systems, receipt formats, and webhook structures.

    How to Implement Cross-Platform Subscriptions in Base44 using Wanilla

    Wanilla unifies subscription management across iOS and web. Your Base44 users can subscribe on either platform and access their subscription everywhere — Wanilla handles receipt validation, entitlement syncing, and cross-platform restore. Android support is coming soon.

    How Wanilla converts your Base44 web app into a native app with Cross-Platform Subscriptions

    Code Integration Example

    Wanilla's cross-platform subscription system works seamlessly:

    • Unified entitlements — a single source of truth for subscription status across iOS, Android, and web
    • Receipt validation — server-side validation for App Store, Google Play, and Stripe receipts
    • Graceful downgrades — handle expiration, cancellation, and billing issues across platforms
    • Migration support — users switching platforms keep their subscription status

    No SDK integration required — Wanilla manages the complexity at the native layer.

    One subscriber, two billing systems

    Most Base44 founders already sell on the web through Stripe before they ever think about iOS. The moment an iPhone app exists, the same person can pay through Apple instead, and you now have two sources of truth for one customer. Getting that wrong produces double charges and support tickets.

    1. Entitlement lives in your Base44 database, not in Stripe and not in Apple. Both providers write to it; your app only ever reads one field.
    2. Apple's server notifications and Stripe's webhooks both feed that field, so a renewal, downgrade, cancellation or failed payment updates access within seconds regardless of where it happened.
    3. Existing web subscribers see no paywall on iOS. They sign in with the same Base44 account and the app unlocks.
    4. New iOS subscribers get full access on the web too, using the same account, which is what Apple's rules expect.

    The pricing decision to make first

    • Apple takes 15% under the Small Business Program versus roughly 3% for Stripe, so many founders price the iOS plan slightly higher or steer new signups to the web before install.
    • Apple does not allow you to tell users inside the app to go and pay on your website, so any steering has to happen before download — in email, on your landing page, in your onboarding.
    • Cancellation is handled by Apple for Apple subscribers; your Base44 account page needs to link to the iOS subscription settings rather than try to cancel it itself.
