Google Play Billing vs Superwall

Google Play Billing lets developers sell digital products and content in Android apps through one-time purchases or subscriptions. It is for digital items; developers selling physical goods or services are directed to the Google Pay SDK. One-time products may be consumable for repeat purchases or non-consumable for a lasting benefit, and can grant permanent access or a particular non-renewable use. Subscriptions grant defined benefits for a set period and support base plans, offers, prepaid plans, and add-on entitlements. The Play Billing Library connects an Android app with Google Play Services to retrieve localized offerings and launch purchase flows. Google recommends a secure backend using the Play Developer API for purchase verification and subscription management. That API can check purchase status and modify or cancel recurring purchases. Cloud Pub/Sub delivers notifications about changes to Google Play-managed subscriptions. Purchases that are not acknowledged within three days are automatically refunded. Google says service fees vary by developer and transaction; its overview says 97% of developers distribute apps and use Google Play at no charge, and 99% of developers subject to a service fee are eligible for a fee of 15% or less through available programs. The listed plan is free.

Superwall is an AI-powered monetization stack for subscription and mobile apps that helps teams build, test, and optimize paywalls. Its paywall engine serves iOS, Android, React Native, Flutter, and Web from one web-standards-based runtime, with SDKs for Swift, Kotlin, React Native, Expo, and Flutter. Entitlement APIs, purchase APIs, webhook delivery, direct SQL access to subscription data, and integrations are free on every plan. Paywall revenue is billed at 1% when attributed to Superwall-rendered paywalls; subscriptions purchased outside Superwall are free. The service includes campaigns, audiences, templates, charts, in-app purchase and subscription support, and A/B testing. Superwall AI can use documentation, SDK source, account data, and analytics queries without a usage limit. App-to-Web Checkout sends U.S. iOS users to Stripe Checkout in Safari and links purchases back to the app. Startup costs $49 a month plus 1% of MAR; Scale costs $199 a month plus 1% of MAR.
