About this gig
Stuck on In-App Purchases or Subscriptions? I'll Get Them Working Fast.
Adding in-app purchases shouldn't be the reason your app launch gets delayed. I specialize in seamless IAP and subscription integration for iOS and Android StoreKit, Google Play Billing, and RevenueCat so you can start generating revenue without the technical headaches.
Whether you need a single one-time purchase, a full subscription paywall, or a complete freemium monetization system, I build clean, tested, and App Store/Play Store-compliant integrations that just work.
- iOS (StoreKit/StoreKit 2) & Android (Google Play Billing).
- Subscription tiers, free trials & promotional offers.
- RevenueCat integration for cross-platform management.
- Receipt validation & restore purchases.
- Clear communication, on-time delivery.
Let's turn your app into a revenue-generating product. Message me before ordering if you have a custom setup happy to advise on the best approach for your project.

FAQ
Do you work with both iOS and Android apps?
Yes, I handle in-app purchase and subscription integration for both platforms — using StoreKit/StoreKit 2 for iOS and Google Play Billing for Android. I also work with cross-platform frameworks like Flutter and React Native.
What is RevenueCat, and do I need it?
RevenueCat is a subscription management platform that simplifies handling purchases across iOS and Android from one backend. It's not required, but I recommend it if you want easier analytics, entitlement management, and reduced maintenance long-term.
Will my app pass App Store/Play Store review with the IAP setup?
Yes, I follow Apple and Google's current guidelines for in-app purchases to help ensure a smooth review process. I also test purchase flows using sandbox/test accounts before delivery.
What do you need from me to get started?
Ideally your app's source code (or repo access), App Store Connect / Google Play Console access, and details on the products/subscription tiers you want to offer.
