Simplify In-App Subscriptions with RevenueCat — One SDK, Zero Headaches

Tired of wrestling with App Store receipts and Play Store quirks? Let RevenueCat handle your subscription backend so you can focus on building your app.

🚀 What is RevenueCat?
RevenueCat is a subscription management platform for mobile apps. It acts as a backend-as-a-service for in-app purchases (IAP), allowing you to:

Implement subscriptions across iOS, Android, and web with a single SDK.

Automatically handle purchase validation, renewals, cancellations, and restorations.

Gain deep analytics into your app’s recurring revenue.

💡 Think Firebase, but for in-app subscriptions.

🧩 Problems RevenueCat Solves
Without RevenueCat, you'd need to:

Validate receipts from App Store & Play Store manually.

Write custom logic for subscription renewals.

Sync subscription status between platforms.

Deal with edge cases like billing retries, refunds, user switching devices, etc.

That’s a full-time job. With RevenueCat, it’s 2 lines of code.

import 'package:purchases_flutter/purchases_flutter.dart';

void main() async {
await Purchases.configure(PurchasesConfiguration("your_api_key"));

// Fetch available packages
Offerings offerings = await Purchases.getOfferings();
if (offerings.current != null) {
await Purchases.purchasePackage(offerings.current!.availablePackages[0]);
