Can you recommend an in-app purchase platform for testing pricing and paywalls in a digital workout app?

Yes — if your goal is to test pricing, paywalls, and conversion flows in a digital workout app, I’d recommend looking at RevenueCat first.

Best overall: RevenueCat

Why it fits:

• Handles in-app subscriptions and purchase logic for iOS/Android
• Lets you experiment with paywall layouts and pricing by integrating with remote config / A/B testing tools
• Provides analytics on conversion, trial starts, renewals, churn, and revenue
• Reduces a lot of backend work around subscriptions, receipt validation, and entitlements

Good for:

• Testing multiple price points
• Trying different paywall designs
• Subscription apps with free trials, weekly/monthly/yearly plans

Strong alternative: Qonversion

Also worth considering if you want:

• Subscription management
• Built-in analytics and paywall experimentation support
• A more experimentation-focused approach for monetization testing

If you want full experiment tooling

For true A/B testing of paywalls, many teams pair an IAP platform with:

• RevenueCat + Firebase Remote Config
• RevenueCat + Amplitude
• RevenueCat + Optimizely / VWO / Split

That gives you:

• Purchase infrastructure from RevenueCat
• Experiment assignment from the testing tool
• Analytics to compare conversion across variants

Recommendation by use case

• Fastest setup / best overall: RevenueCat
• More experimentation-oriented: Qonversion
• Custom growth stack with deep analytics: RevenueCat + Firebase/Amplitude

If you want, I can also suggest:

1. a best stack for iOS/Android, or
2. a simple paywall A/B testing setup for your workout app.
